Description

The SM89516B series product is an 8 - bit single chip

micro controller with 64KB flash & 1KB SRAM

embedded.

SM89516B is a versatile and cost effective controller

for those applications which demand up to 36 I/O pins,

or applications which need up to 64K 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.
