Mouser Electronics has begun supplying STMicroelectronics (ST)'s Arm Cortex-M33-based mainstream MCU 'STM32C5' series. The STM32C5 targets entry-level embedded applications while offering enhanced connectivity, security, and processing performance, aiming to meet development demands in the industrial, smart home, and robotics sectors.

Mouser announced on the 2nd that it is supplying the STM32C5 series. The product is designed for applications requiring both cost efficiency and functional expansion, such as smart homes, consumer electronics, industrial equipment, robotics, wearables, and computer peripherals.

The STM32C5 is based on an Arm Cortex-M33 core operating at 144 MHz and supports a Floating-Point Unit (FPU) and DSP instructions. According to ST, this product delivers a CoreMark score of 593, achieving three times higher performance than typical Cortex-M0+ products.

Memory supports up to 1MB flash and 256KB RAM. It also provides a dedicated flash area for EEPROM software emulation. ST explained that through a design based on a 40nm manufacturing process, it lowered dynamic power consumption while implementing sensing, control, and user interface functions even in limited space.

Communication and security features are also included. The STM32C5 supports one Ethernet interface, octoSPI peripherals, and up to two FDCANs. It also features hardware encryption capabilities for SAES, SPKA, and HUK, and packages are available from 20 pins to 144 pins.

Mouser also supplies ST’s NUCLEO-C5A3ZG and NUCLEO-C542RE development boards along with the STM32C5 series. Both development boards are based on the STM32Cube software ecosystem and support prototype development and verification through expansion connectors, an ST-LINK debugger, and an Arduino Uno V3 compatible environment.

In the MCU market, there is a growing demand to integrate connectivity, security, and real-time processing capabilities beyond simple control functions. The expanded supply of the STM32C5 is expected to broaden the options for developers who need to consider network and security features even in entry-level designs.
