Product details

80 MHz Cortex-M4 with 256 KB Flash — the ultra-low-power workhorse

Peripheral set — CAN, USB, QSPI, and a 12-bit ADC array

This MCU carries a CANbus interface, full-speed USB, Quad-SPI for external memory expansion, and a 16-channel 12-bit ADC plus two 12-bit DACs. The LCD driver peripheral can directly segment-drive a glass LCD panel without an external controller. The 52 I/O pins in the 64-LQFP package give enough GPIO for a keypad, encoder inputs, and a parallel display bus.

Active lifecycle — no EOL risk for production builds

It is ROHS3 compliant.
