NXP发售LPC11U30 USB微控制器（128K闪存）
支持多种内存和封装选择的简单易用、超低功耗ARM Cortex-M0 USB解决方案现已上市
恩智浦半导体NXP Semiconductors N.V. 近日宣布推出基于ARM Cortex-M0处理器的简单易用、功耗超低LPC11U30系列USB微控制器， 目前该系列产品已向全球各大经销商铺货。从获奖的LPC11U00系列4 KB EEPROM、12 KB SRAM，到恩智浦嵌入式128KB闪存（256字节可擦写），该系列产品有多种内存配置可供选择。 此外，LPC11U30系列微控制器有效功耗仅为110 uA/MHz，可完美支持游戏鼠标、键盘、血糖仪、遥控玩具等USB2.0对大容量本地存储的应用需求。
The LPC11U30 supports the latest USB 2.0 specification with Link Power Management (LPM) mode, which allows a device to enter a suspended state when not in use. It also offers on-chip power profiles optimized for specific power levels, including a Low Current mode ideal for battery-powered applications that only connect to USB for occasional charging or data download. With multiple USB drivers integrated into ROM, the LPC11U30 microcontroller maximizes flash memory utilization and provides fully tested APIs that enable easy USB integration, which can be further enhanced by using nxpUSBlib, NXP’s fully featured open source USB library.
