Looking for programmable EEPROM to store calibration info

[elset191]

My company is looking for an EEPROM or similar device that we can read and write to using RS-485.  We intend to store only a few KB worth of calibration information on it. In our benches we have 12 and 24 V power sources to power the device.  Does anyone here have any recommendations or any idea where we can find such a device?  Alternative method suggestions are also welcome.  We've never done anything like this and we're kind of flailing about looking for a solution.

Buy an arduino and an rs-485 shield.

Anyone thinking about EEPROM and Calibration might also consider TEDS:

What is a Transducer Electronic Data Sheet (TEDS)?

How about an inexpensive micro-PLC?

24VDC, RS-232/485, 6.4kwords data memory with battery backup in case the main power goes out (not sure how easy it is to read/write via RS-485). Plus you make lights blink in pretty patterns while doing absolutely nothing!

Another vote for Arduino.  NI has a toolkit, the firmware is open source, plenty of community support and at $17 with free prime shipping.
