Microchip 推出两个带集成式超低功耗 LCD 控制器的 AVR XMEGA 系列

Image of Atmel's AVR® XMEGA® LCD PeripheralMicrochip 为广受欢迎的 AVR® XMEGA™ 微控制器 (MCU) 系列添加了 LCD 控制器。 集成 LCD 控制器可降低设计复杂性和系统总体成本，还可在电能计量、家庭自动化、气候控制、工业控制、体育器材、玩具、电子令牌、医疗设备、电动工具、火灾报警系统以及其它需要用户界面的系统应用中实现超低功耗。

AVR XMEGA B 微控制器的 LCD 控制器对 100 引脚 B1 器件支持多达 4x40 段，对 64 引脚 B3 器件支持多达 4x25 段。 如果您的应用不需要包括所有的 LCD 段，可使用多达 16 个 LCD 引脚作为通用 I/O (GPIO) 引脚。

这些超低功耗的 LCD 驱动器只需 3 µA 即可运行 LCD 显示屏，并拥有多项省电功能，例如内置对比度控制、ASCII 字符映射、可编程段闪烁、插拔模式、集成式 LCD 缓冲器、集成式 LCD 电源（独立于电源电压）和滚动文字支持等。 除了集成式 LCD 控制器以外，AVR XMEGA B 器件还具有通过内部振荡器工作的全速 USB 器件、双通道 12 位 ADC、DMA 控制器、事件系统、picoPower® 技术以及 AVR 单周期 CPU。
