ATMEGA128A-AUR

ATMEGA128A-AUR is an 8-bit AVR microcontroller. The high-performance, low-power microchip 8-bit AVR® RISC-based microcontroller combines 128Kb flash memory with read-while-write capabilities, 4Kb EEPROM, 4Kb SRAM, 53 general purpose I/O lines, 32 general purpose working registers, a 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 5.5 volts. By executing powerful instructions in a single clock cycle, this device achieves throughputs approaching one MIPS per MHz, balancing power consumption and processing speed.
