General Description
The SM8951B series product is an 8-bits single
chip micro controller with 4KB flash embedded. It
provides hardware features and a powerful
instruction set, necessary to make it a versatile
and cost effective controller for those applications
demand up to 32 I/O pins or need up to 4KB flash
memory either for program or for data or mixed.
To program the flash block, a commercial
programmer is cap-able to do it.
