Product details

It is designed for industrial control, sensor interfacing, and general-purpose embedded applications where a balanced mix of processing throughput, peripheral integration, and a compact footprint is needed.

Connectivity and I/O

With 34 I/O lines and interfaces including I²C, SPI, SSI, and UART/USART, this part can handle a mix of sensors, serial displays, and motor encoders without external glue logic. The two 10-bit ADC channels are useful for analog feedback loops — current sensing or potentiometer readback — but at 10-bit resolution, precision measurement applications will need an external ADC.
