It runs at 16 MHz and carries 2 KB of Flash program memory with 128 bytes of RAM. With 10 general-purpose I/O lines, I²C and SPI serial interfaces, an internal oscillator, and an 8-channel 10-bit ADC, this part is sized for sensor nodes, simple control loops, and human-interface devices where every microamp matters.
The part is current-production and available through independent distribution.
It has 2 KB of Flash program memory (2K x 8). Combined with 128 bytes of RAM, this is a tight memory footprint suited for small control loops, sensor readout, and simple communication protocols.
The supply voltage maximum is 3.6 V, so the I/O pins are not 5 V tolerant. Interfacing with 5 V logic requires level translation or an external voltage divider.
