ATMEGA168A-PU Atmel 8 Bit 16K AVR Microcontroller

• Model: IC-ATMEGA168A-PU
• Shipping Weight: 6g
• 65 Units in Stock
• Manufactured by: ATMEL
• ATmega168A Datasheet

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

• 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
