STMicro STM32F7x0 & H7x0 Value Line Microcontrollers Deliver Cortex-M7 Performance at Lower Cost

STMicro introduces their first Arm Cortex-M7 microcontrollers in 2014 with STM32F7 series clocked up to 200 MHz. The next year, Atmel – now Microchip – announced SAM S70 & SAM E70 Cortex-M7 MCU families clocked at up to 300 MHz, STMicro up the ante to 400 MHz with their STM32H7 family in 2016, and more recently NXP launched their i.MX RT series “crossover” processor with the Cortex-M7 reaching up to 600 MHz. AFAIK, nobody has tried to push the clock speeds higher, but STMicroelectronics most recently unveiled STM32F7x0 & H7x0 Value Line microcontrollers with the same performance level as their earlier STM32F7 and STM32H7 MCUs, but with a lower price by reducing the amount of internal flash. Three Cortex-M7 value line families have been introduced: STM32F730 entry-level MCU @ 216MHz with 64KB flash, 8KB data / instructions cache, 256KB RAM and 16KB+64KB TCM (Tightly Coupled Memory). The microcontroller also includes […]

GAPUINO GAP8 is a $229 RISC-V MCU Developer Kit for A.I. Applications

GreenWaves GAP8 is a low power RISC-V “MCU class” processor with eight compute cores optimized for artificial intelligence applications, and its main selling point is the ability to do tasks like computer vision or audio processing at very low power, even good enough to run on batteries. When we first covered GAP8 RISC-V processor at the beginning of the year, the company also mentioned a development kit comprised of GAPDUINO Arduino compatible board, a sensor board, and a QVGA camera module to experiment with the solution. The board and development kit are now easier to purchase as the devkit is sold on SeeedStudio for $229. GAPuino board specifications: SoC – GAP8 IoT Application Processor with 8x RISC-V compute cores, 1x RISC-V fabric controller core delivering up to 200 MOPS at 1mW and >8 GOPS at a few tens of mW Memory / Storage – HyperBus combo DRAM/Flash with 512 Mbit […]

LAPIS ML62Q1622 is a General Purpose 16-bit MCU with an LCD Driver

So this morning I received an email about some seminar & workshop about LAPIS microcontroller, including a free ML62Q1622 evaluation board. OK, good. But wait. Who is LAPIS? I have certainly never seen any projects with Lapis MCUs, and probably have never heard of them. It turns out OKI SEMICONDUCTOR Co.,Ltd. established in 2008 from a spin-off of Oki Electric Industry Co., Ltd, changed the company name in to LAPIS Semiconductor Co.,Ltd in 2011. LAPIS is also part of ROHM Semiconductor group. Anyway, it was a good opportunity to find out more about ML62Q1622 micro-controller, and related evaluation boards & tools. Lapis Semi ML62Q1622 is part of ML62Q1600 group of 16-bit microcontrollers whose block diagram is shown above. ML62Q1622 MCU key features & specifications: CPU – 16-bit RISC CPU (CPU name: nX-U16/100) clocked @ up to 32 MHz Coprocessor for multiplication and division Program Memory – 64Kbyte Data Memory – […]

Microsoft Introduces Azure Sphere OS Linux Operating System for Certified Microcontrollers (MediaTek MT3620 for now)

Last year, Microsoft announced they were working with Mediatek on Project Sopris Secure WiFi MCU, based on Mediatek MT7687 MIPS microcontroller with 7 properties enhancing security (Hardware-based Root of Trust, failure reporting etc…). The company has now unveiled a complete secure IoT solution with Azure Sphere comprised of three main components: Azure Sphere certified secured MCUs which combine real-time and application cores with built-in Microsoft security technology and connectivity. The first compatible MCU will be Mediatek MT3620, which differs from MIPS based Project Sopris, as it features one Cortex A7 and two Cortex M4 cores as well as WiFi connectivity. Azure Sphere OS that provides four layers on top of the hardware: security monitor, custom Linux kernel, on-chip connectivity services to Azure Sphere Security Service, and app containers for computer (A7 core) or/and real-time I/Os (M4 cores). Azure Sphere Security Service, a secure cloud service for Azure Sphere device that […]
