STM32C0 Series MCU
STM32C0
The STM32C0, ST's most affordable 32-bit microcontroller, makes 32-bit capabilities accessible to all developers.
Today, the STM32C0 series offers microcontrollers providing from 16 to 32 Kbytes of flash memory and packages ranging from 8 to 48 pins. In 2024, the STM32C0 will provide microcontrollers with up to 256 Kbytes of flash memory, available in packages with up to 64 pins.
Why Choose STM32C0?
Enter the STM32C0, a revolutionary microcontroller designed for entry-level applications, offering a price and packages that compete with those of 8-bit MCUs. With an expected upgrade memory configuration of up to 256 KB of flash and 32 KB of RAM in 2024, the STM32C0 goes beyond traditional 8-bit capabilities. Notably, it will incorporate a crystal-less USB controller for efficient power delivery via USB. The internal clock feature eliminates the need for an external crystal, reducing the bill of materials and simplifying PCB layout complexity. ST ensures a wide range of packages, allowing PCBs relying on small 8-bit microcontrollers to retain their form factor.
The following table highlights the value proposition for designers switching from their current 8-bit microcontroller solutions to the new 32-bit architecture of the STM32C0, (further details in the following link): New STM32C0: More memory and lower prices will convert more systems to 32-bit
