ATmega88V

Availability: In production

Deviceimage

Summary

The mega88 is a 8k variant of the mega48, which was allegedly designed to fill the need for an 1.8V mega8-like part. Its siblings are the mega48 and mega168; 4- and 16k flash variants of the same. The ATmega48, ATmega88 and ATmega168 differ only in memory sizes, boot loader support, and interrupt vector sizes. In ATmega88 and ATmega168, the Boot Loader Support provides a real Read-While- Write Self-Programming mechanism. NB! The PDIP-28 version has only 6 ADC channels, while the other packages has 8 channels.
Notice that this is the 1.8 V version
