It packs 22 general-purpose I/O lines, an internal oscillator, and an 8-channel 10-bit ADC — enough for a single-loop sensor controller or a simple UART/SPI bridge in an industrial box.
ROHS3 compliant.
The core runs at 8 MHz. That is enough for slow sensor polling, UART communication, and simple control loops.
