GSC93BC66

ISSUED DATE :2006/06/14 REVISED DATE : GSC93BC46/56/66 3-wire Serial EEPROMs 1K/2K/4K The GSC93BC family provides 1K, 2K and 4K of serial electrically erasable and programmable read-only memory (EEPROM). The wide Vdd range allows for low-voltage operation down to 1.8V and up to 5.5V. The device, fabricated using traditional CMOS EEPROM technology, is optimized for many industrial and commercial applications where low-voltage and low-power operation is essential. The device is accessed via a 3-wire serial interface.

The ORG pin is used to select between x8 and x16. When the pin is connected to Vcc, x16 mode is selected. Otherwise, the ORG pin should be grounded in order to select x8 mode. The interface foe the GSC93BC46/56/66 is accessed through four different signals: Chip Select (CS), Data Input (DI), Data Output (DO), and Serial Data Clock (SK). The Chip Select (CS) signal must be pulled high before issuing a command through the Data Input (DI) pin. The Serial Data Clock (SK) signal is used in conjunction with the Data Input (DI) pin.
