SPI PSRAM

Jun 13, 2007 2 Replies

Does anyone know of a 64 or 128Mbit SPI PSRAM?



I know that SST has some combination flash/PSRAM devices.



You could certainly create one using some logic and a standard parallel style PSRAM (typically 48 or 56 pin fine pitch BGAs). I would like something smaller and cheaper.



The application would be for audio delay lines so speed is not really a factor.

SPI RAM is a blindspot in the market. Even Video RAM faded.

You probably have to build one using a CPLD or uC and a DRAM. For smaller sizes, there are FRAM SPI devices from Ramtron, and they look like SPI RAM.

There was talk of JTAG Flash, but I have not seen real info yet.

That was my impression as well. I guess there really are not that many applications where you can tolerant very slow access RAM.
