Hyper RAM Forum Discussions

Hello,

We are using the S70KL1282 HyperRAM chip with the i.mx rt 1064 and for now we've only been using the IP Bus. We've managed to read all registers on the part shown below: 

FlexRAM Config Reg0 - Die 0: 0x8f2f
FlexRAM Config Reg0 - Die 1: 0x8f2f
FlexRAM Config Reg1 - Die 0: 0xffc1
FlexRAM Config Reg1 - Die 1: 0xffc1
FlexRAM Die Manuf - Die 0: 0x3030
FlexRAM Die Manuf - Die 1: 0x3030
FlexRAM ID Reg0 - Die 0: 0x0c81
FlexRAM ID Reg0 - Die 1: 0x4c81
FlexRAM ID Reg1 - Die 0: 0x0001
FlexRAM ID Reg1 - Die 1: 0x0001

I've hooked up a scope and writing the data all seems correct, however on the read I am always getting 4 bytes of "garbage" data, in this case 0x0051dd5d. I've mostly been trying to read/write from memory address 0, but it seems I always get the "garbage" bytes with any memory address. Any help or suggestions on where to go would be appreciated. 

Hello, 

I'm using this part in my design S70KL1283GABHB020. 

Could you please share design guidelines, reference schematic, and simulation model for this part? 

If I have the previledge to buy a cheaper 3000mhz ram over a more expensive 2666mhz(the fastest speed of cpu support) both same size 16gb, will it work if i downclock it to 2666mhz through bios? Or will i have issues?

I'm using the product S70KL128, but the document were not found, Could you help me to find it.

Thanks!

We are looking for a way to integrate external RAM (possibly as large as 16MB) in our Project. Right now, we can only use Quad-SPI to connect the RAM-IC to our µC.

After looking at the Datasheets for the S27-Series, I haven't found a possibility to set the ICs up for a Quad-I/O-Mode.
Can you confirm that, or is there a way that i have overlooked?

The Exelon F-RAMs seem to be compatible with QSPI, though the Memory Density is not as large as we might need it.
Is there another product, that we could use?

Thank you and regards,

Fabian
