Product Summary

The ATMEGA168P is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATMEGA168P achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.

Parametrics

ATMEGA168P absolute maximum ratings: (1)voltage on any pin except RESET with respect to ground: -0.5 to Vcc+0.5V;(2)storage temperature: -65 to 150℃;(3)operating temperature: -55 to 125℃;(4)voltage on RESET with respect to ground: -0.5 to 13.0V;(5)DC current per I/O pin: 40mA;(6)maximum operating voltage: 6.0V;(7)DC current Vcc and GND pins: 200mA.

Features

ATMEGA168P features:(1)131 powerful instructions - most single-clock cycle execution; (2)32 x 8 general purpose working registers; (3)fully static operation; (4)up to 20 MIPS Throughput at 20 MHz; (5)on-chip 2-cycle multiplier; (6)two 8-bit timer/counters with separate prescaler, one compare mode; (7)one 16-bit timer/counter with separate prescaler, compare mode, and capture mode; (8)real time counter with separate oscillator; (9)six PWM channels; (10)power-on reset and programmable brown-out detection; (11)internal calibrated oscillator; (12)external and internal interrupt sources.
