ATmega48

Availability: In production

Summary

The mega48 is a 4k variant of the mega88, which was allegedly designed to fill the need for an 1.8V mega8-like part. Its siblings are the mega88 and mega168; 8- and 16k variants of the same. The ATmega48, ATmega88 and ATmega168 differ only in memory sizes, boot loader support, and interrupt vector sizes. In ATmega48, there is no Read-While-Write support, and no separate Boot Loader Section. The SPM instruction can be executed from the entire Flash. NB! The PDIP-28 version has only 6 ADC channels, while the other packages has 8 channels.
