Product details

The 50 MHz core handles 8-channel 10-bit ADC sampling and simple PID loops. The 42 I/O lines support parallel sensor interfaces and I²C, SPI, UART connectivity.

On-chip EEPROM saves an external memory IC

The 1K x 8 EEPROM block is unusual at this Flash density — it stores calibration constants, node addresses, or fault logs without an external serial EEPROM, saving board space and a supply line. The 16 KB Flash is sized for small-footprint firmware with field-update headroom via the in-system programming (ISP) port.
