Summary of STM32C0: The Most Affordable 32-Bit MCU That Will Change the Way You Design
The STM32C0 series from STMicroelectronics democratizes 32-bit technology by offering affordable microcontrollers ranging from 16 KB to a planned 256 KB of flash memory. Powered by the Arm Cortex-M0+ processor at up to 48 MHz, these devices bridge the gap between low-cost 8/16-bit MCUs and high-performance 32-bit solutions. By expanding package sizes to include 64-pin options, the portfolio aims to deliver enhanced memory and peripherals while maintaining cost efficiency for a broader range of applications.
Parts used in the STM32C0 Microcontroller Series:
- STM32C0 microcontrollers
- Arm Cortex-M0+ processor
- On-chip flash memory (16 KB to 256 KB)
- 8-pin packages
- 48-pin packages
- 64-pin packages
- Peripherals
The STM32C0 microcontroller series from ST aims to bring the benefits of 32-bit technology within reach of all developers.
Currently the STM32C0 offers options with as little as 16 KB flash memory available in small 8-pin packages, up to 32 KB flash in devices with 48 pins. However, by 2024 ST plans to expand the STM32C0 portfolio significantly.
Newer STM32C0 microcontrollers will provide up to 256 KB of on-chip flash memory, more than an eightfold increase from current capacities. Package sizes will also increase, with 64-pin options joining the lineup.
By continuing to drive down costs while increasing memory and peripheral capabilities, ST hopes the STM32C0 can make the performance and functionality of 32-bit MCUs accessible for an even wider range of applications and budgets. Developers stand to gain powerful, full-featured 32-bit solutions at prices previously only affordable with 8-bit microcontrollers.
