Description

The SM8954A series product is an 8 - bit single chip micro controller with 16KB on-chip flash and 1K byte RAM embedded. It is a derivative of the 8052 micro controller 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 SM8954A a versatile and cost effective controller for those applications which demand up to 16 I/ O pins for PDIP package or up to 36 I/O pins for PLCC/QFP package, or applications which need up to 16K byte flash memory for program data.To program the on-chip flash memory, a commercial writer is available to do it in parallel programming method.
