SM8958A 8-Bits Micro-controller With 32KB flash & 1KB RAM embedded Specifications subject to change without notice contact your sales representatives for the most recent information. Ver 2.1 SM8958A 08/2006 1 Product List SM8958AL25, 25MHz 32KB internal flash MCU SM8958AL33, 33MHz 32KB internal flash MCU SM8958AC25, 25MHz 32KB internal flash MCU SM8958AC40, 40MHz 32KB internal flash MCU Description The SM8958A is an 8-bit single chip micro controller with 32KB 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 32 I/O pins for PDIP package or up to 36 I/O pins for PLCC/QFP package, or applications which need up to 32K 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.
