SM5964C40J

Product Summary

The SM5964C40J 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. The SM5964C40J has 5-channel SPWM build-in. With its hardware features and powerful instruction set, the SM5964C40J is 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.
