SM8954A 8-Bits Micro-controller With 16KB flash & 1KB RAM embedded Specifications subject to change without notice contact your sales representatives for the most recent information. Ver 2.1 SM8954A 08/2006 1 Product List SM8954AL25, 25MHz 16KB internal flash MCU SM8954AC25, 25MHz 16KB internal flash MCU SM8954AC40, 40MHz 16KB internal flash MCU 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. 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 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.
