Description

The SM59128 series product is an 8-bit single chip

microcontroller embedded with 128KB on-chip flash with

In-System Programming (ISP) capability and

1024 bytes RAM. It is a derivative of the 8052 microcontroller

family. In addition, SM59128 has IIC interface which is

compatible with standard VESA DDC/CI and built in 4-channel

SPWM. User can access on-chip expanded RAM by its ‘bank

mapping direct addressing mode’ scheme. With its hardware

features and powerful instruction sets, 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 or QFP package, or applications

which need up to 64K bytes flash memory for program and/or for

data.

To program the on-chip flash memory, commercial writers are

available by parallel programming method. On the other hand,

the on-chip flash memory can be programmed through either

parallel or serial interface with its ISP feature.
