Description  
The SM5964 series product is an 8 - bit single chip  
micro controller with 64KB flash & 1K byte RAM  
embedded. It has In-System Programming (ISP)  
function and is a derivative of the 8052 micro controller  
family. It has 5-channel SPWM build-in. 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.

8-bit Unsigned Division  
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.
