EEPROM for the TDS9092 embedded computer

32k byte serial EEPROM for the I²C bus:

l This extended EEPROM can replace the 256 byte PCF8582. Simply remove the PCF8582 8-pin DIL from its socket and insert the 24WC256.

l Can be a few meters from the computer board without having to add buffers.

l The TDS9092 drives the device at a speed of about 17k baud. Transfers are synchronous and handshaken.

l Unlike a RAM, no back-up battery is needed and the stored data is safer from corruption.

l Can be used for data logging up to 64k bytes (2 chips of 32k bytes), text and menus.

l Up to 4 chips can be attached but (without modifiction) the library program supports only two.

l The library file _24WC256.TDS contains the driver words for byte and word transfer and for defining non-volatile variables.
