空调红外遥控器是通常由两节碱性电池供电，通过38KHZ 红外载波调制与挂机或者柜机单向通讯的便携式设备。

由于其成本低廉，低功耗等特点不仅在空调，还在其它家电及玩具等领域得到了广泛应用。基于便携及电池供电的

要求，系统的超低功耗及可靠性设计是首要目标之一。本文针对应用中对低功耗，高集成度的要求，采用

MSP430F415 超低功耗MCU，实现按键扫描，LCD 显示，红外发送等完整功能。-Infrared remote control air conditioning is usually made two alkaline batteries, 38KHZ IR carrier modulation by hook or Guiji-way communication with portable devices.

Because of its low cost, low power consumption, not only in air conditioners, appliances and toys are still other fields has been widely used. Based on portable and battery-powered

Requirements, low power consumption and reliability of the system design is one of the primary objectives. This paper applications for low-power, high integration requirements, using

MSP430F415 ultralow power MCU, achieve key scan, LCD display, full function infrared transmitter and so on.
