Description  
The SM5964 series product is an 8 - bit single chip  
microcontroller with 64KB flash & 1K byte RAM embed-  
ded. It has In-System Programming (ISP) function and  
is a derivative of the 8052 microcontroller family. It has  
5-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 either for program or for data or  
mixed.  
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  
Page free jumps  
8-bit Unsigned Division  
8-bit Unsigned Multiply  
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.
