Description
The SM2964 series product is an 8 - bit single
chip micro controller with 64KB 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 64 K byte memory either for program
or for data or mixed.
To program the flash block, a commercial programmer
is capable to do it.
