Description
The SM89516 series product is an 8-bit single chip micro
controller with 64KB flash & 1KB RAM embedded. It is a
derivative of the 8052 micro controller family. With its
hardware features and powerful instruction set, it’s straight
forward to make it a versatile and cost effective controller
for those applications which demand up to 32 I/O pins for
PDIP package or up to 36 I/O pins for PLCC/QFP package,
or applications which need up to 64KB 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.
