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 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 hard-
ware features and powerful instruction set, it’s straight for-
ward 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 pack-
age, or applications which need up to 64K byte flash mem-
ory 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 paral-
lel or serial interface with its ISP feature.
