Flash DOC to NV SRAM

Jun 28, 2004 3 Replies

Hi folks,



I have a evaluation SBC (the LogicFlex from jkmicro

formatting link
) with a 8 MB Flash DOC.



Would anyone know whether a NV SRAM, capacity 4 MB to 8 MB, could be plug compatible, i.e. plug in and go ? I am not an embedded specialist (a systems integrator/ tinkerer who manages to solder a little with only the occasional finger singed ) but would anyone have some links and part numbers or something for me to follow up ? Look at maxim for NV RAM but the range is mind numbing for me.



I need to write log data fairly intensively and would like to have the issue of limited life span of flash memory resolved for my peace of mind.



Thanks in advance.



Regards, Harnek

The board and bios will only support a)DiskOnChip, b)512kbyte SRAM of some type, non-volatile is probably ok, or c)SST28SF040 512kbyte flash. Nothing else is likely to work and is not supported by JK micro.

Hi Stewart,

Thanks for the reply. Which 512kbyte non-volatile SRAM, specifically a part number and website link please, would be suitable for the Logicflex SBC to replace the flash DOC with ? Sorry, I am not able to work that out for myself so I have to ask.

Thanks Harnek

Harnek,

The part that we are referring to is the Battery Backed Clock/Cal &

512K SRAM chip that goes into the 32 Pin DIP socket.

Our part #20-0087 ST Micro part # ST M48T512Y-70PM1

Hope this information helps,

Brian
