2nd generation Kinetis high performance

[kenmcdaniel]

1) will the 2nd generation Kinetis integrate a nand or ddr controller?

2) on the current K66 (without NFC) how would you implement nand with ecc on flexbus?

3) can MQX handle ecc?

4) are there any planned high performance Kinetis products to include controllers for current high performance memories like the K61?

Hi, Ken,

I suggest you use K70, the K70 has SDRAM controller, NAND flash controller, for example MK70FX512VMJ15 can reach up to 150MHz frequency, has cache for code and data.

The required access timing to access NAND flash is totally different from accessing SRAM or NOR flash, in other words, you can not use FlexBus to access NAND flash, fortunately, the K70 has on-chip NAND Flash controller to access NAND flash. It also has DDR SDRAM controller to access DDR SDRAM.

I think the driver on MQX supports NAND flash access with ECC function, but I need check.

This is the website of K70:
