HyperBus/QSPI Flash and RAM

[a8Chcx]

Hi,

I am using K66F and KV58F for our controller. I want to expand the flash and RAM on Flexbus or SPI of K66F and KV58F?

Can anyone tell if I can us Hyperbus/QSPI Flash and RAM? Is there any recommend way to expand Flash and RAM by using less IO pins?

Thanks,

Christie

Hi, Christie,

Of course, you can use FlexBus to extend NOR flash and normal SRAM, as you said the connection needs more pins, it needs address bus, data bus and control bus.

The K66F and KV58F has spi module, but it is normal spi module instead of qspi or hyperbus, in other words, KV58 and K66 can not connect with qspi or hyperbus SRAM or flash.

We have Kinetis K8x, they have on-chip qspi module, which can connect with flash or SRAM with qspi interface.

Hope it can help you

Hi Xiangjun,

Thank you.

Can I use SPI on K66F and KV58 to connect SPI flash? If yes, can you recommend any SPI/QSPI flash that can be used on K66F and KV58?

Thanks,

Christie
