The SST89E516RDx and SST89V516RDx are members of the FlashFlex51 family of 8-bit microcontroller products designed and manufactured with SST’s 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’s customers. The devices use the 8051 instruction set and are pin-for-pin compatible with standard 8051 microcontroller devices.

摘 要 基于AC/DC 开关电源PWM 控制芯片的工作原理,分析了其产生功耗的主要来源,提出了两种减小芯 片功耗的方法,一是采用电流源和电流沉串联方式构成的输出驱动电路,通过消除cmos 电路的瞬态短路导通现 象,降低该电路模块的功耗;二是采用跳周工作模式,使芯片在轻载和空载情况下,降低功率开关管的开关损耗。

This paper presents a low-power asynchronous implementation of the 80C51 microcontroller. It was realized in a 0.5 µ m cmos process and it shows a power advantage of a factor 4 compared to a recent synchronous implementation in the same technology. The chip is fully bit compatible with the synchronous implementation, and timing compatible for external memory access. The circuit is a compiled VLSI-program, using Tangram as VLSI-programming language and the Tangram tool set to compile the design automatically to a standard-cell netlist. This design approach proves to be powerful enough to describe the microcontroller and derive an efficient implementation. Further, it offers the designer the possibility to explore various alternatives in the design space.
