Product details

50 MHz Cortex-M0 with 8 KB Flash — what it means for the BOM

Industrial temperature range and supply flexibility

Rated for -40°C to 85°C. Supply range is 1.8 V to 3.6 V. Internal oscillator is included.

I/O and connectivity in a 32-HVQFN package

28 general-purpose I/O lines are brought out on a 32-HVQFN with exposed pad — the pad must be soldered to a ground plane for thermal and electrical contact. The part includes I²C, SPI, and UART/USART interfaces, plus an 8-channel 10-bit ADC. The brown-out detect, POR, and watchdog peripherals are built in, so external supervisor ICs can often be omitted on simple boards.
