The ATmega88 is an electronic integrated circuit microcontroller produced by the Atmel corporation. It has the basic Atmel AVR instruction set. One of the packaging configurations is the dual in-line package (DIP). It has {{nowrap|23 I/O pins}} and operates at up to {{nowrap|20 MHz}} for clock speed. It has an 8-bit core and 8K flash (program) memory. {{cite web |url=http://www.atmel.com/devices/atmega88.aspx |title=ATmega88- Atmel Corporation |access-date=2012-02-27 |archive-url=https://web.archive.org/web/20131029185450/http://www.atmel.com/devices/atmega88.aspx |archive-date=2013-10-29 |url-status=dead }}
Many of Atmel's microcontrollers in this line have similar instruction sets, so if an engineer learns the instruction set from one of their microprocessors, this knowledge is transferable to other microcontrollers in the line.
The ATmega168 is a variant with 16 KB Flash memory.{{Cite web |title=ATmega88/ATmega168 |url=https://ww1.microchip.com/downloads/en/DeviceDoc/Atmel-9365-Automotive-Microcontrollers-ATmega88-ATmega168_Datasheet.pdf}}
