SST89V54RD数据手册Microchip中文资料规格书

描述 Description

The SST89V54RD is a member of the FlashFlex family of 8-bit microcontroller products 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 SST customers. The device uses the 8051 instruction set and are pin-for-pin compatible with standard 8051 microcontroller devices.
