The Atmel ATmega168A is a 16K 8-bit microcontroller based on the AVR architecture and replaces the now obsolete ATmega168. Many instructions are executed in a single clock cycle providing a throughput of almost 20 MIPS at 20MHz. The ATMEGA168A-PU comes in an PDIP 28 pin package and is suitable for use on our 28 pin AVR Development Board.

Features include:
  • High Performance, Low Power Design
  • 8-Bit Microcontroller Atmel® AVR® advanced RISC architecture
    • 131 Instructions most of which are executed in a single clock cycle
    • Up to 20 MIPS throughput at 20 MHz
    • 32 x 8 working registers
    • 2 cycle multiplier
  • Memory Includes
    • 16KB of of programmable FLASH
    • 512 Bytes of EEPROM
    • 1KB SRAM
    • 10,000 Write and Erase Cycles for Flash and 100,000 for EEPROM
    • Data retention for 20 years at 85°C and 100 years at 25°C
    • Optional boot loader with lock bits
      • In System Programming (ISP) by via boot loader
      • True Read-While-Write operation
    • Programming lock available for software security
  • Features Include
    • 2 x 8-bit Timers/Counters each with independent prescaler and compare modes
    • A single 16-bit Timer/Counter with an idependent prescaler, compare and capture modes
    • Real time counter with independent oscillator
    • 10 bit, 6 channel analog to digital Converter
    • 6 pulse width modulation channels
    • Internal temperature sensor
