Hi,
I'm looking for the following. A customer of mine is developing a machine which requires 32K of memory for storage of non-volatile data (to survive power-outs, CPU crashes, application crashes, etc.) for keeping track of the state of the machine.
Approximately 32K is needed, which must be capable of r/w of small packets of data (1..20 bytes) at a frequency of 100 Hz. Up to 25
clients should be able to simultaneously access this memory. Flash memory looks unusable because it only supports a limited number of 'writes', so I'd like to use memory with an unlimited number
of write-accesses.
Ethernet is already available for all clients, so an Ethernet-based server looks ideal. I'm thinking about using a PC104 x86 CPUboard with a PCMCIA card, but before I start designing this, does anyone on this list know if such a module already exists 'off the shelf'? (I found one in Germany for CAN, but with a proprietary protocol, so useless...)
