Nuvoton’s NuMicro M091 Arm Cortex-M0 microcontroller targets industrial sensors

nuvoton NuMicro M091 Smart Industrial Sensors Series

Nuvoton recently launched the NuMicro M091 Series of microcontrollers, these are 32-bit MCUs based on the Arm Cortex-M0 core, featuring 4 sets of operational amplifiers with 8 MHz gain bandwidth (GBW), 4 sets of 12-bit DAC, up to 16 channels of 2 MSPS 12-bit SAR ADC, a temperature sensor, and extensive I/O options. The MCU supports the NuMaker evaluation board and various third-party IDEs making this an ideal device for industrial sensing, smart sensors, and precision instrumentation applications. Previously we have seen Nuvoton release MA35H0 and MA35D1 both MPUs are based on Cortex-A35 cores, feel free to check those out if you are interested in the topic. Nuvoton NuMicro M091 MCU specifications: Processor ARM Cortex-M0 core Maximum clock speed: 72 MHz Memory Flash – Up to 64 KB SRAM – 8 KB LDROM – 2 KB (for user program loader) SPROM – 512 Bytes (for security protection) Analog Features 4x […]

600 MHz STM32H7R/S Cortex-M7 MCUs feature 620KB SRAM, 64KB boot flash, optional NeoChrom GPU

STMicro STM32H7RS

STMicro has launched the high-performance 600 MHz STM32H7R/S Arm Cortex-M7 microcontrollers: the STM32H7R3/S3 General-purpose MCU lines, and STM32H7R7/S7 graphics MCU lines adding a NeoChrom 2.5D GPU. Both ship with a large 620KB SRAM and a small 64KB boot flash. The reason for the small boot flash is to have the application code and data stored off-chip memory ICs to provide more flexibility to customers when it comes to the choice of memory type and capacity to fulfill the application requirements and lower the BoM cost. The “S” in the STM32H7S microcontrollers stands for Security with a crypto/hash engine that can help the final product achieve SESIP Level 3 and/or PSA Certified Level 3 certifications. Many of the specifications are similar to the STM32H7 microcontrollers, but performance is better going slightly faster than the 550MHz STM32H7 MCUs added in 2020, and the STM32H7R/S adds some new features: 200 MHz Hexadeca SPI […]

AMD announces the Spartan UltraScale+ FPGA family for cost-sensitive and IO-intensive applications

amd spartan ultrascale+

The Spartan UltraScale+ FPGA family is the latest inclusion to AMD’s Cost-Optimized portfolio, a series of FPGAs designed to balance cost, power, and form factor with affordability. The UltraScale+ FPGA family is designed for cost-sensitive, low-power applications requiring high I/O count and substantial security. Devices in the Spartan UltraScale+ family offer a high I/O to logic cell ratio for FPGAs built in 28nm and lower process technology (the highest in the industry, according to AMD), consume up to 30% less power than compared to the previous generation, and feature robust security features that outclass the rest of the Cost-Optimized portfolio. This FPGA family is built on the same UltraScale+ architecture as previous Artix and Zynq products. They are the first AMD UltraScale+ FPGAs to feature a hardened DDR memory controller and PCIe Gen4 x8 support, “providing both power efficiency and future-ready capabilities for customers.” AMD Spartan UltraScale+ specifications: System Logic […]

Embedded Open Source Summit 2024 schedule – Embedded Linux, Zephyr OS, and Real-time Linux

Embedded Open Source Summit 2024

The Embedded Open Source Summit 2024 (EOSS 2024) will take place on April 16-18 and the Linux Foundation has already announced the schedule with conference sessions, lightning talks, and birds of a feather (BoF) sessions covering embedded Linux, Zephyr OS, and real-time (RT) Linux. While I won’t be attending in person, I still find it interesting to check out the schedule as we may learn more about the current status of embedded Linux. So I’ve created my own little virtual schedule out of the available talks. Tuesday, April 16 – Day 1, Embedded Open Source Summit 2024 9:05 – 9:45 – No, It’s (Still) Never Too Late to Upstream Your Legacy Linux-Based Platforms by Neil Armstrong, Linaro Nearly 7 years ago, Neil already spoke about this subject in Berlin, and it’s still very true. Do you maintain or used to maintain a Linux-based board or SoC off-tree? Then there are […]

Waveshare ESP32-H2-DEV-KIT-N4-M – A Low-cost ESP32-H2 development board going for $6.65

Waveshare ESP32 H2 DEV KIT N4 M Dev Board

The Waveshare ESP32-H2-DEV-KIT-N4-M is a development board based on the ESP32-H2, available for only $6.65 on Aliexpress, but you’ll also find it on Amazon and Waveshare’s official store. This is a significant price drop compared to last year’s official Espressif ESP32-H2-DevKitM-1 board, which was priced at $10 without including shipping costs and with a similar design. In 2021, Espressif Systems introduced the ESP32-H2 to the world. However, it wasn’t until 2023 that they released their first development board. Since then, there haven’t been many products built around this new module. Some exceptions include the Olimex ESP32-H2-DevKit-LiPo, LILYGO T-Panel, and the ESP Thread Border Router/Zigbee Gateway board, all of which feature the ESP32-H2 chip. Waveshare ESP32-H2-DEV-KIT-N4-M specifications: Wireless module – ESP32-H2-MINI-1 MCU – Espressif Systems ESP32-H2 32-bit RISC-V microcontroller at up to 96 MHz with 320 KB SRAM, 128 KB ROM, 4 KB LP memory, Bluetooth 5.2 LE/Mesh, and 802.15.4 (Zigbee/Thread/Matter) radios.
