PRODUCT OVERVIEW
SN8P2711A
is modified from SN8P2711. Good internal high RC frequency 16MHz
±
2%. Good high
noisy protecting performance for household application.
z
SN8P2711 is compatible to SN8P2711A.
z
Better IHRC performance from 16MHz
±
5% to 16MHz
±
2%.
z
Good brown out reset production.
z
SN8P2711 code can transfer to SN8P2711A directly. Program the original SN8 of SN8P2711
into SN8P2711A directly without declare SN8P2711A in source code and re-compile again.
