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.
