Arm cores are designed by Arm Holdings and licensed to semiconductor manufacturers for integration into their products. I fully agree with your PSoC assessment — if you can’t make use of the virtual peripheral and touch sense capabilities, it’s far less interesting. Old-timers associate the 8051 with “old and slow” because the original was a 12T microcontroller — each machine cycle took 12 clock cycles to complete. Thanks, I am looking forward to reading more of your website and updates! The Infineon XMC1000 family extends up to the XMC1400, with 200 KB of flash, 16 K of RAM, a slightly-faster 48 MHz core clock, and a 64-pin package. Doubling-up on UARTs was a popular decision overall: the other 8051s — the EFM8 and the N76 — bring a second UART, as do the PIC16 and PIC32MM, along with the LPC811. Last word, the STM8S003F3 has been so successful that Nuvoton has now its pin-to-pin compatible SSOP-20 chip N76E003. All Microchip PIC parts, Atmel SAM D10, and the RL-78 all support bit-addressable register access. Though its not a $1 part TI have a special offer($4.30) on the new FR2433 Launchpad if you want to grab some, I just got 2. So…https://danchouzhou.blogspot.com/2018/06/sdccn76e003-1t-8051.html – you can look here for start with N76E003 (use option Translate in Chrome, advise by Cap.). Their header files are little more than register names attached to addresses. My only real bug-bears on the PIC MPLABX IDE is the removal of the optimization on the non-paid for C Compilers which happens to the 32 bit and 24 bit compilers as well as the 8 bit ones! All other vendors copy-and-paste the same newlib and newlib-nano options. I love the nearly-stock Eclipse-based environment that System Workbench for STM32 provides, and the ST-Link and excellent Discovery/Nucleo boards seals the deal for me. Holtek has a wide range of application-specific MCUs that integrate this core with HV power and other goodies. The newer MPLABX was a tough pill to swallow. This tool handles communication callbacks particularly effectively — the code generator creates an interrupt that handles the underlying ISR details, but then directly invokes a statically-declared callback function that’s stubbed out conveniently for the user. What this tests: Memory and 16-bit math performance per microamp, essentially. Header files should come chock-full of documentation, so you can keep your focus on your code — instead of having to jump around inside PDFs. It was also designed for C compilers, too — with 32 registers available at all times, compilers can efficiently juggle around many operands concurrently; the 8051, by comparison, has four banks of eight registers that are only easily switched between within interrupt contexts (which is actually quite useful). And I see from this article that there is a lot more! I think every hacker and advanced hobbyist really ought to throw $10 at AliExpress/Taobao and get some STC15 and STC8 parts — just for fun. And that’s what I want people to think about as they walk away from this microcontroller review. Processor Expert provides a unique development experience for rapid-prototyping, which may be enough to lure some developers away from newer parts. The STM32F0 was the lowest-power Arm microcontroller in the round-up, and also one of the easiest to use. Great work and very much appreciated. In the end, consider µVision as nothing more than the free editor you get when you download C51 or MDK-ARM. The peripheral register view will break down each register into the bits that are set and cleared — but I would have preferred hover-over descriptions of the registers and the bits they command. Swedish IAR has a really really good IDE and compiler, all for free (as long as the code doesn’t exceed 8kB). What results is an IDE that is extremely easy to use — great for students and hobbyists who many find the Eclipse project properties pane to be… well, a pain. Cypress and Microchip’s SAM D10 went with CMSIS-DAP debuggers on their boards, while the Nuvoton used their proprietary NuLink for both their Arm and 8051 controllers. Kudos ! Now the bad: Atmel START is extremely clunky to use. Let’s dig in a bit: I’ve plotted a cycle-count cumulative distribution above — I’ve included the STC15, an older part closely related to the STC8 (and mentioned extensively in the STC8 review). Oxygen (4.7.0) was just released in June, so the newest IDEs — System Workbench, MCUXpresso, and Code Composer Studio — and are still on Neon (4.5). In my opinion, the peripheral register viewer is one of the most important debug windows — even more important than the disassembly view. Peripheral configuration and bring-up is generally a drop in the bucket when compared to the time required to implement an entire commercial embedded project — but if you’re working on tiny projects (either hobbyist stuff, or simple proof-of-concept engineering demos), having a code-gen tool can noticeably speed up the development cycle. The schematics were clearly documented, and I consider these changes to be completely routine — just the price of admission of trying to do low-power development. It would be a massive undertaking to go over every single peripheral on these MCUs, but I’ll focus on the ones that all MCUs have in common, and point out fine-print “gotchas” that datasheets always seem to glance over. Low-cost tools, a free cross-platform Eclipse-based IDE, and a slew of easy-to-program peripherals should get both professionals and hobbyists interested in exploring this platform. Bringing together all of this information is absolutely great! I spent several minutes in front of my bench grinder cleaning up all the snap-apart boards so they could accept standard 0.1” headers and jumpers. I’m actually less worried about the Holtek HT66; it’s efficient peripheral library essentially uses no RAM, and 256 bytes of user data is plenty of space for an ultra-low-power MCU that’s designed for only the most basic duties. IntelliSense with most AVR is available from VisualGDB 2. You can get a quite full featured (a/d, dma, multiplier etc) part in the family for $1.10. I miss the parts from ZILOG. On the other end of the spectrum, among the 8051, only Silicon Labs maintains their own IDE for the EFM8 — both the N76 and STC8 only support µVision. Really Great! Silicon Labs has a full EFM8 peripheral library, but Simplicity Configurator does not call into it nor include it automatically — it just initializes peripherals, using raw register manipulation. Prefeitura Municipal de Primavera do Leste / MT Todos os Direitos Reservados. But I’d really like to see Microchip provide a PicKit-priced debugger with UPDI support — and allow off-board debugging the way their PIC Curiosity Boards do. The tool managed to generate extremely compact code — the best in the round-up of code configurator tool (though this is also just a product of the PIC16 architecture), and, like Atmel START’s 8-bit code, read like something a human would write. I’m wondering if Microchip has slashed prices on these AT89 parts recently — if I remember right, at the time of the review, these parts were all more than $1 @ 100 qty. Raisonance conducted a benchmark a few years ago that confirms everything I’ve written on the strengths and weaknesses of GCC.9Full disclosure: Raisonance has a stake in GCC, as they use it in their Ride7 proprietary IDE.jQuery("#footnote_plugin_tooltip_9").tooltip({tip:"#footnote_plugin_tooltip_text_9",tipClass:"footnote_tooltip",effect:"fade",fadeOutSpeed:100,predelay:400,position:"top right",relative:true,offset:[10,10]}); One minor annoyance with GCC is that its backend considers SFR accesses as an “optimization” — so with the optimizer off, it uses fairly slow code for accessing peripherals. You have to place everything on the schematic — even pins and clock sources. Nuvoton provided a code configurator tool for their M0, but I mention it here only to dissuade you from thinking it has absolutely any value at all, in case you see an advertisement for it. Before committing to higher-speed PIC32MX devices, I’d have to investigate the flash caching. Again, a multi-byte FIFO helped immensely. 33. Microchip produces microcontrollers of three basic designs: an 8-bit, a 16-bit, and a 32-bit. Still driven by a sluggish core that clambers along at one-fourth its clock speed, the PIC16 has always been best-suited for peripheral-heavy workloads. But because the tool is intelligent enough to ignore strategically-placed user code, it’s easy to customize the generated code to suit your purposes. To handle this shortcoming, XC8 can create a software stack on PIC18 devices, which have enough indirect addressing operators to support this. Part: LC87F1M16 There’s not much to like in the LC-87. And I’d have suggestion to make another review of ‘under fiver’ wireless SoC’s. The entire IDE’s scale is much more dense than NetBeans. Keil’s fame ensues from their acclaimed 8051 compiler, C51, introduced in 1988 — but since 1997, their compilers have also shipped with their in-house IDE, Keil µVision. As a plus, the tool can generate project formats that target all popular development ecosystems — and not just their official System Workbench for STM32. Atmel code generator is still god-awful (IMO), and the code bloat it generates really turns me off the SAMD10; a great shame as the chip is very good. I’ve had good luck with the relatively new STM32L0 series. St-link is low low cost ($2) and personally I have used the same st-link to program/debug msp432, stm32, and mkl03. 16. The online community is massive, and as clunky as I find Atmel START to be, I have to applaud its support for Makefile-based project generation. Actually, there is a standalone tool for loading code into this part. It is great to see creative score keeping and a homogenized analysis among different micro variants. Even though NetBeans has a lot of the same features, the UI is sparsely populated with the bare minimum of buttons you need to get your job done. I assume this is why they don’t pre-define user callback function stubs, as these would get overwritten on subsequent regenerations of the code. All dev boards tested have built-in on-board debuggers, but they varied widely in capabilities. Both these parts are capable of 20 MHz operation, so it’s a little silly to have to down-clock them because Atmel doesn’t build these parts on a modern process allowing 1.8-3.6V operation at full speed, like most other parts tested. And unlike Processor Expert, DAVE designers appear to have designed the generated code (as well as XMClib in general) for better optimization than Processor Expert, where even a single bit-toggle function ends up nearly completely unoptimized — taking 40 cycles to complete. DAVE makes setting up these complex peripherals painless, and the 38-pin TSSOP chips will be substantially easier to solder than the 0.5mm QFNs and QFPs you usually end up with in these pin counts. Cypress PSoC Creator is the official — and only — development environment available for Cypress’s line of PSoC devices, and encompasses a project management system, text editor, schematic capture tool, code generator, and debugger. This part has terrible power consumption, few peripherals, and the worst development environment I saw in this review. This system seems like it would be popular among people with an electronics — not programming — background. Extreemly core efficient and <1USD as well. The STM8 has a Harvard architecture, but uses a unified address space. The tool supports initializing almost all peripherals of almost all STM32 devices — an impressive feat on its own. Oddly, Atmel can’t seem to combine these specs — there is no 100-pin, 256 KB flash, 16 KB RAM megaAVR that is in current production. I have used everything from 8 pin PIC12F’s to 144 pin PIC32MZ parts and found that the upgrade paths are rather easy as the pinouts rarely change within the same package, and once you get used to the IDE and have a good code base to work from I can develop new designs fairly quickly. Renesas RL-78 extends up to the R5F101SLAFB, with 128-pin package, 512 KB of flash, 32 KB of RAM, and a slightly-faster 32 MHz clock speed. The ARM7TDMI-S didn’t come with any GPIO designs, or provisions for UARTs or ADCs or timers — it was designed as a microprocessor. Are there other options? The code editor in Eclipse is definitely a stand-out among IDEs tested — especially if you’re coming from other IDEs. Should be called Atmel STOP. Do they even have a list of which shields are compatible, and which ones are incompatible with various boards? These parts also had the most inconsistent speeds — sometimes if I restarted my computer, they would be significantly slower or faster. As an example, I have no idea how to show the excellent Macro Expansion view in NetBeans, other than pressing Ctrl-Alt and clicking on a macro. What this tests: This gives some good intuition for how the platform works — because it is so low-level, we’ll be able to easily look at the assembly code and individual instruction timing. At the bottom of the pack are the 4T and 3T architectures — the Holtek HT66, the Microchip PIC16, and the Sanyo LC87,  These 8-bit architectures must essentially load the working register with the toggle bit, XOR it into the port latches, and then jump back to the top. Memory? Yes, I know you can disable these extensions with the NOEXTEND compiler directive… but obviously then you can’t use these directives. Part: ATSAMD10D14A Atmel is positioning their least-expensive ARM Cortex-M0 offering — the new SAM D10 — to kill off all but the smallest TinyAVR MCUs with its performance numbers, peripherals, and price. https://www.digikey.com/product-detail/en/stmicroelectronics/STM32F318K8U6/STM32F318K8U6-ND/5268270 1.3$ with FPU. Whatever usable for sensor apps etc. It has the fastest debug speeds, supports any target voltage, and has unlimited software breakpoints. I got burned by the function documentation a bit — but was able to get it working after quite a bit of reading. It’s time for a good ol’ microcontroller shoot-out. This uses SVD, a standardized set of tools for generating header files and descriptions of such. But most of the things I look at cost much more than $1. Thank you for sharing your valuable experience. And if you let that number creep then you get thousands of parts. There’s a hover-over break-down of the register into its individual bits, but these use the same short-form datasheet names, don’t provide descriptions, and don’t contain enumeration values for multi-bit fields (or any explanation at all). Excellent low-power consumption, arrayed comms and timer peripherals, plus a good code-gen tool built into the free Eclipse IDE makes this part a strong competitor against the PIC24 and MSP430. I wish I have saw this eariler which will save my a couple hundard parts buying debuggers and wrong chips. But I still can’t believe that you can get a powerful machine like this for only a dollar. Eclipse — across nearly all vendors — provided the best out-of-the-box experience out of all the IDEs I tested. Filling flash up to 16 KB took 10.84 seconds. I am enjoying these series of articles, please when you can add more to STM32F4 controllers. I’ll focus on manufacturer-provided or manufacturer-suggested IDEs and compilers (and these will be what I use to benchmark the MCU). I cannot imagine how much time and effort you put into it! Arm, especially, has seen a mass migration to GCC — even Arm Holdings (who own MDK-ARM) take part in GCC’s upkeep, and distribute binary releases of it on their site. Other vendors turned in results hovering in the 500-800 ksps range. The Silicon Labs EFM8LB1 is the top-of-the-line part in the EFM8 family — these top out at 64 KB of flash, 4.25 KB of RAM, and a relatively-small 32-pin package. I was glad to see information about Renasas – that’s one brand I’ve wondered about but thought it was kind of out of reach. Other Eclipse-based IDEs are on older versions — with Kinetis Design Studio and DAVE being on the oldest release (Luna SR2 — 4.4.2). Your review here covers nearly everything I would have done and then some. I’ll minimize power consumption by lowering the frequency of the CPU as much as possible, using interrupt-based UART receiver routines, and halting or sleeping the CPU. Anyone who complains about IDE bloat and download registration walls should immediately check out Holtek HT-IDE3000 (yes, that’s what it’s called). For speed, the EFM8 brings 900 ksps to the table — beat out only by ST and Infineon whose ADCs can clock at up to 1 Msps. I ended up forcing it to generate code in a “generated” folder inside an existing MCUXpresso project. Thank you for the good job you made !!!!! These are the sorts of things I’ll be exploring while evaluating the software for the MCU architecture. Well i believe every experienced engineer finds it’s way to work effectively with mcu weaknesses after crossing the 8 bit gap and moving to 32 bits .As to what is the best to use the most important thing is “Second source ” or compatible chip.
