ARM Cortex-M4 core MCUs
The NXP Cortex-M4 family will be an important part of NXP's High Performance Mixed Signal portfolio, providing embedded system designers with easy-to-program 32-bit DSCs which are code- and tool-compatible with other NXP ARM-based MCU products. Implemented using an ultra low-leakage 90-nm process technology, the family will be the most energy efficient 32-bit embedded processors for digital signal controllers. NXP's Cortex-M4 processor-based family is planned to be introduced to the broad market at end of 2010.
NXP Cortex-M4系列是NXP高性能混合信号产品组合中重要的组成部分，向嵌入式系统开发人员提供易编程32位DSC，其代码、工具与NXP其他基于ARM的MCU产品都能兼容。由于使用超低漏 90nm 处理工艺，这个系列成为数字信号控制器最具能量效率的32位嵌入式处理器部件。NXP Cortex-M4 处理器系列计划在2010年末推向市场。
