Product details

48 MHz Cortex-M0 with USB and CAN in a 20-pin TSSOP

It packs a USB 2.0 full-speed device controller and a CAN 2.0B interface into a 20-pin TSSOP package, which is unusual for this pin count — most 20-pin MCUs in this class omit CAN or USB.

Peripheral set and memory sizing for the BOM

The 6 KB SRAM handles a couple of 1 KB DMA buffers plus stack and global data; if your application needs a large frame buffer or a TCP/IP stack, step up to the 8 KB or 16 KB SRAM variants in the STM32F042 family.

STMicroelectronics continues to manufacture the STM32F0 series, and the base product number STM32F042 spans multiple density and package options that share the same peripheral set, easing a future density migration without a board respin.

What is the difference between STM32F042F6P7 and STM32F042C6?

The STM32F042F6P7 comes in a 20-pin TSSOP package with 16 I/Os, while the STM32F042C6 is in a 48-pin LQFP with 38 I/Os. Both share the same 48 MHz Cortex-M0 core, 32 KB Flash, 6 KB SRAM, and USB+CAN peripherals. The C6 variant gives you more GPIO for parallel interfaces or additional sensors; the F6P7 is the space-constrained choice.
