SPI slave on LPC802

[shiven]

Dear NXPs, 我们在寻找一颗SPI 做slave能达到12Mhz或者16Mhz的产品，调过检索看到了LPC的data sheet。对这颗MCU的SPI描述感到困惑： 1.这颗MCU是否有DMA？（规格书里面有提到，但是没有列出来）； 2. 这颗MCU的clock只有15Mhz，但是在SPI描述里面，做slave的话，SPI可以支持17.8Mhz，这可以实现吗？ 感谢解答~！ Shiven

Hello shiven,

1)LPC802 doesn't support DMA.

2)Where said "做slave的话，SPI可以支持17.8Mhz，" ? I don't think it can.

3) You can consider LPC845 or LPC824 :
