Description
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.
Features
&Internally organized as 128x8 or 64x16 (1K),

&3-wire serial interface bus
&Date retention: 100years
&High endurance: 1,000,000 Write Cycles
&2MHz (5V) clock rate
&Sequential read operation
&Self-timed write cycle (10ms max)
