MICROCONTROLLER DRAINS BATTERIES DOWN TO 0.9V

摘要

Silicon Laboratories based its new C8051F9xx line of 8-bit microcontrollers on a new version of the Intel 8051 core, which its designers recast as a pipelined, 100-MIPS CPU. The company adds mixed-signal and analog features, such as high-precision data converters. The new parts operate at voltages as low as 0.9V to extract the greatest possible life from a single-ceil battery. The devices have onboard boost converters that can supply the microcontroller and as much as 65 mW of power for external circuitry, which allows you to use power from a primary cell until the battery drains at 0.9V.
