Description
The SM8958B series product is an 8 - bit single chip
micro controller with 32KB flash & 1KB SRAM
embedded.
SM8958B is a versatile and cost effective controller for
those applications which demand up to 36 I/O pins, or
applications which need up to 32K byte flash memory
either for program or for data or mixed.
To program the on-chip flash memory, a commercial
writer is available to do it in parallel programming
method.
