Description
The SM59264 series product is an 8-bit single chip
micro controller with 128KB on-chip flash which
including 64KB program flash & 64KB data flash and
1K byte RAM embedded. It has In-System
Programming (ISP) function and is a derivative of the
8052 micro controller family. It has TWSI interface
which is compatible with standard VESA DDC/CI. It
has 4-channel SPWM 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 and/or for data.
To program the on-chip flash memory, a commercial
writer is available to do it in parallel programming
method. The on-chip flash memory can be programmed
in either parallel or serial interface with its ISP feature.
