Description
The SM89516A series product is an 8 - bit single chip micro
controller with 64KB on-chip flash and 1K byte RAM
embedded. It is a derivative of the 8052 micro controller
family. It has 5-channel SPWM build-in. 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 64K byte flash memory for
program data.
To program the on-chip flash memory, a commercial writer
is available to do it in parallel programming method.
