1 PRODUCT OVERVIEW
SN8P2604A
is modified from SN8P2604. Good high noisy protecting performance for household
application.
SN8P2604 is compatible to SN8P2604.
Better power on reset.
Good brown out reset production.
SN8P2604 code can transfer to SN8P2604A directly. Program the original SN8 of SN8P2604
into SN8P2604A directly without declare SN8P2604A in source code and re-compile again.
