Product Overview

The ATMEGA128A-AU is a high-performance, low-power 8-bit AVR RISC-based Microcontroller combines 128kb flash memory with read-while-write capabilities, 4kb EEPROM, 53 general purpose I/O lines, 32 general purpose working registers, real time counter, four flexible timer/counters with compare modes and PWM, two USARTs , a byte oriented Two-wire serial interface, an 8-channel/10-bit A/D converter with optional differential input stage with programmable gain, programmable watchdog timer with internal oscillator, SPI serial port, a JTAG (IEEE 1149.1 compliant) test interface for accessing the on-chip debugging and programming and six software selectable power saving modes. The device operates between 2.7 to 5.5V. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.
