K60 interface with a parallel nor flash

javiervicandi — Wed, 08 Jul 2015 17:04:22 GMT

Hello,

We need to use a parallel NOR flash memory with the K60. We have not found a memory with multiplexed address and data (size of 512Mb or 1Gb) to connect directly to FlexBus.

A solution without external latches or changing to serial interface?

Thanks

Hi,

K60 Flexbus module provides non-multiplexed address and data busses connection, which based on customer K60 pin resource.

If K60 could not provides enough non-multiplexed address pin resource, it need to use the address latches.

Wish it helps.

Have a great day,
Ma Hui

Hi,

This is our case. We have pins only for multiplexed mode. We know some flash memory as the MT28GU01GAAA2EGC0SIT with A/D MUX but it needs 1.7V-2V supply.

We will check if it is possible reduce the VDD from 3.3V to 2V.

Best Regards
