SST89C58RC数据手册Microchip中文资料规格书

描述 Description

The SST89C58RC is a member of the FlashFlex family of 8-bit micro controllers designed and manufactured with patented and proprietary SuperFlash CMOS semiconductor process technology. The split-gate cell design and thick-oxide tunneling injector offer significant cost and reliability benefits for customers. It uses the 8051 instruction set and is pin-for-pin compatible with standard 8051 micro controller devices.
