8 Bit MCU, AVR ATmega Family ATmega128 Series Microcontrollers, 20 MHz, 128 KB, 44 Pins, TQFP

Product Overview
The ATMEGA1284P-AU is a low power CMOS 8bit microcontroller based on AVR enhanced RISC architecture in 44 pin TQFP package. This device achieves throughputs approaching 1MIPS per MHz by executing powerful instructions in a single clock cycle. This allows system designer to optimize power consumption versus processing speed. The ATMEGA1284P-AU has internal calibrated RC oscillator, on-chip analogue comparator, programmable watchdog timer with separate on-chip oscillator, two 8bit timer/counter with separate pre-scaler and compare mode, two 16bit timer/counter with separate pre-scaler, real time counter with separate oscillator and six PWM channels.

Up to 20MIPS throughput at 20MHz
128KB of in-system self programmable flash program memory
4KB EEPROM and 16KB internal SRAM memory
