AT93C57W-10SI [Microchip]

The AT93C46/56/57/66 is a series of serial EEPROMs with 1K, 2K, 4K bits of memory. They operate at low voltages (1.8V to 5.5V) and feature a 3-wire serial interface. The devices are available in 8-pin PDIP, 8-lead JEDEC and EIAJ SOIC, and 8-lead TSSOP packages. They are optimized for industrial and commercial applications requiring low power and low voltage. The memory organization is user-selectable (x8 or x16) via the ORG pin. The devices have self-timed write cycles (10 ms max) and high reliability with 1 million write cycles endurance, 100 years data retention, and >4000V ESD protection.
