Product List
SM2958C16, 16 MHz 8KB internal memory MCU
SM2958C25, 25 MHz 8KB internal memory MCU
SM2958C40, 40 MHz 8KB internal memory MCU
Description
The SM2958 product is an 8 - bit single chip micro control-
ler with 32 KB 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 32 KB
flash memory either for program or for data or mixed.
To program the flash block, a commercial programmer
is capable to do it.
