Mouser Electronics, the industry leader in New Product Introduction (NPI), is now stocking the STM32C5 Arm Cortex-M33-based microcontrollers from STMicroelectronics. This product is designed to support the development of smart home appliances, consumer products, industrial equipment, robotics, wearables, and computer peripherals that are cost-effective and easy to implement.
The STMicroelectronics STM32C5 series available at Mouser utilizes an Arm Cortex-M33 core running at 144MHz (with FPU, achieving 593 CoreMark) and standard DSP instructions. Its design eliminates the need for external accelerators, bringing performance improvements to low-cost microcontrollers. The product delivers up to 3x the performance of standard Cortex-M0+ products, with improved RAM/Flash ratios, featuring up to 1MB of Flash memory and 256KB of RAM. It also includes a dedicated flash region for EEPROM software emulation.
Furthermore, based on ST’s proprietary 40nm manufacturing process, the design improvements realize space-saving while suppressing dynamic power consumption. It incorporates latest features for sensing performance, smoother control, and superior user experience. It comes with one Ethernet interface, octoSPI peripheral, and up to two FDCAN ports, along with hardware encryption capabilities for SAES, SPKA, and HUK. Packages range from 20 pins to 144 pins.
Mouser also stocks STMicroelectronics development boards including the NUCLEO-C5A3ZG (for STM32C55x/STM32C562 and STM32C59x/5A3) and the NUCLEO-C542RE (for STM32C53x/542). The NUCLEO-C5A3ZG, supported by the STM32Cube software ecosystem, provides a flexible and low-cost environment for prototype development. It allows easy expansion through multiple connectors for dedicated shields, leveraging the Nucleo open development platform. The NUCLEO-C5A3ZG integrates an ST-LINK debugger/programmer, eliminating the need for external probes. The NUCLEO-C562RE utilizes the STM32 Nucleo-64 platform with compatibility for Arduino Uno V3 connectors and ST morpho headers, allowing for easy functional expansion with various shields.
