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
  • Qtouch library support
  • JTAG (IEEE std 1149.1 compliant) interface
  • 8 channel, 10bit A/D converter
  • Operating voltage range from 1.8V to 5.5V
  • 32 programmable I/O lines
  • Two programmable serial USART, two wire serial and master/slave SPI interfaces
  • Operating temperature range from -40°C to 85°C
