Description
The SM8951A/8952A series product is an 8 - bit single chip
micro controller with 4/8 KB flash embedded. It provides hard-
ware features and a powerful instruction set, necessary to
make it a versatile and cost effective controller for those appli-
cations demand up to 32 I/O pins or need up to 4/8 KB flash
memory either for program or for data or mixed.
To program the flash block, a commercial programmer is
capable to do it.
