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.
