Description

The SM8958A is an 8-bit single chip micro controller

with 32KB 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

32K 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.

Four 8-bit I/O ports for PDIP package

Four 8-bit I/O ports + one 4-bit I/O ports for

PLCC or QFP package

Full duplex serial channel

Bit operation instruction

Industrial Level

8-bit Unsigned Division

8-bit Unsigned Multiply

BCD arithmetic

Direct Addressing

Indirect Addressing

Nested Interrupt

Two priority level interrupt

A serial I/O port

Power save modes: Idle mode and Power

down mode

Code protection function

Low EMI (inhibit ALE)

Ordering Information

5 channel SPWM function with P1.3 ~ P1.7
