Description
The ATAR080 is a member of Atmel’s family of 4-bit single-chip microcontrollers. It
contains ROM, RAM, parallel I/O ports, one 8-bit programmable multifunction
timer/counter with modulator function, voltage supervision, interval timer with watch-
dog function and a sophisticated on-chip clock generation with external clock input,
integrated RC-, 32-kHz and 4-MHz crystal-oscillators.
