Description
The SM79164 series product is an 8 - bit single chip micro
controller with 64KB on-chip flash and 4K byte RAM
embedded. It is a derivative of the 8052 micro controller
family. It has 8-channel PWM build-in. User can access
on-chip expanded RAM with easier and faster way by its
‘bank mapping direct addressing mode’ scheme. 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.
