STM32C5 Arm Cortex-M33 MCU
STMicroelectronics MCUs set performance standards for cost-sensitive devices in mainstream embedded applications while ensuring design simplicity for developers
The STMicroelectronics STM32C59x/5A3 series provides up to 1 MB of Flash memory, 256 KB of RAM, an Ethernet interface, octo‑SPI support, and as many as two FDCAN peripherals. It includes hardware security features such as SAES, SPKA, and HUK, and is available in package options ranging from 32 pins to 144 pins. Prototyping is straightforward with the NUCLEO‑C5A3ZG board and the STM32Cube development ecosystem.
Features
- Built on an Arm® Cortex®-M33 core running at 144 MHz with FPU, featuring standardized DSP instructions
- 3x the performance of a typical Cortex-M0+ product on the market
- Higher RAM/Flash ratio than typical entry-level products
- Dedicated Flash area for E²PROM software emulation
- RRP starting at 0.64 cts 10 ku
- Reduced BOM cost
- Exceptional value/price compared to typical M0+-based MCUs
- First STM32 MCU to leverage the evolution of the STM32Cube ecosystem, always for free
- Low dynamic consumption with < 80 μA/MHz
- 1% calibrated RCI oscillator at a temperature of -20°C to +105°C
- Full performance at full temperature range
- Wide packages offer from 32 pins to 144 pins starting at 3 mm x 3 mm
- Up to three ADCs, two COMPs, a high analog content, and one OPAMP
- Ethernet 10/100, 2 FDCAN, USB, and OCTOSPI
- Secure PKA, SHA, HUK, SCA, and SESIP3 & PSA Certified Level 3 target certifications
