It runs at 16 MHz and packs 2 KB of Flash program memory with 256 x 8 bytes of RAM — a tight memory footprint that suits simple sensor controllers, basic I/O expanders, or battery-monitoring nodes where code size stays under 2 KB.
Memory and peripheral fit
With only 2 KB of Flash and 256 bytes of RAM, this part is not for complex protocol stacks or data logging. It fits applications that run a single control loop, read a few ADC channels, and toggle a handful of GPIOs. The 24 I/O lines, plus I²C, SPI, and UART serial interfaces, give enough connectivity for a simple sensor hub or a LIN-bus node in an automotive body module. The brown-out detect and watchdog timer provide basic system integrity for unattended operation.
