Hi The FTDI chips we will use for USB<->UART communications on the Alpha boards can use an EEPROM chip to store settings. The settings are for example USB vendor/product ID numbers, but also a boatload of settings (see the datasheet for details).
We think we will get by with just the default settings if we don't care about the cosmetics with VID/PID for the Alpha, but what if we change our minds? I would like to suggest adding an EEPROM to the schematics, but not populating it in the first manufacturing run. Does anyone see any downside to this? The recommended EEPROM unfortunately does not have a write protect pin, and I haven't had the time to look for a possible replacement chip - if anyone knows of one, that would be another option. /Fredrik
