AT93C66W-10SI-2.7

EEPROM Serial-3Wire 4Kbit 512 x 8/256 x 16 3.3V/5V 8Pin SOIC EIAJ

Description

The AT93C46/56/66 provides 1024/2048/4096 bits of serial electrically erasable programmable read-only memory EEPROM, organized as 64/128/256 words of 16 bits each when the ORG pin is connected to VCC, and 128/256/512 words of 8 bits each when the ORG pin is tied to ground. The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operations are essential. The AT93C46/56/66 is available in space-saving 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead EIAJ SOIC, 8-lead MAP, 8-lead TSSOP, and 8-lead dBGA2 packages.
