STM32C5 Arm® Cortex®-M33 Core Mainstream MCUs

STMicroelectronics STM32C5 Arm^® Cortex^®-M33 Core Mainstream Microcontrollers (MCUs) are designed to support the development of cost-effective applications. This family offers up to 1MB of Flash memory and 256KB of RAM as well as one Ethernet port, octoSPI peripherals, and up to two FDCAN. These MCUs include hardware crypto for SAES, SPKA, and HUK features, and the lines are available in several packages ranging from 20 to 144 pins. For quick prototyping, the user can use either the STMicroelectronics NUCLEO-C5A3ZG (for the STM32C55x/STM32C562 and STM32C59x/5A3) or NUCLEO-C542RE (for the STM32C53x/542) development tools alongside the STM32Cube software ecosystem.
