LPC11U00:彻底的USB解决方案
LPC11U00系列
Delivering robust USB performance at a low price point, LPC11U00 devices are compelling replacements for 8/16-bit USB microcontrollers.The highly flexible USB architecture is, quite simply, a better approach to USB, and the tiny (4.5 x 4.5 mm) TFBGA48 package is especially well suited for mobile and consumer applications. Like NXP’s other ARM-based USB solutions, the LPC11U00 series is supported by easy-to-use software and integrated development platforms that make NXP a one-stop shop for USB. The series is pin-compatible with Cortex-M3 LPC134x devices.
处于低价位却具有强劲的USB性能。LPC11U00将强行取代现有的8/16位USB微控制器。具有高度灵活性的USB架构，简单而更易于实现USB功能，4.5x4.5mm 的TFBGA48封装尤其适用于移动和消费电子。类似于NXP其他基于ARM的USB解决方案，LPC11U00系列配有简单易用的软件，集成了一站式USB开发平台。LPC11U00系列的引脚与Cortex-M3 LPC134x相兼容。
