The X series extends the high end of Freescale's Kinetis 32-bit ARM® Cortex™-M family of MCUs with higher performance, increased memory and integration. X series family members include the same DSP and Floating Point instructions as the Kinetis K series but raises the operating frequency up to 200 MHz - the fastest of any ARM Cortex-M based MCU. Kinetis X series internal memories include 0-4 MByte of flash and 0.5 MByte of SRAM, with multiple off-chip memory options also available for expansion headroom. In addition, the X series offers an advanced suite of connectivity, security and HMI peripherals, all accompanied by Freescale's bundled software enablement.

Cortex-M4的内核（带DSP和FPU），200MHz的主频，带ECC的内置SRAM， DDR2/3的控制器，WVGA的LCD控制器，触摸屏控制器（不知道是电容屏还是电阻屏的）
暂时没有其他更多信息了。

评论一下：F家赶紧把K系列的先出货了吧，去年就发布了，到现在还是工程样片呢。。。
另外200M的主频，挂DDR2，稍显奢侈。。。
另外主频赛跑啊，去年K系列150M，今年STMF4就168，然后X系列就上200。。。
