AT24C64A-10TI-2.7

EEPROM Serial-2Wire 64Kbit 8K x 8 3.3V/5V 8Pin TSSOP

Description

The AT24C32A/64A provides 32,768/65,536 bits of serial electrically erasable and programmable read only memory EEPROM organized as 4096/8192 words of 8 bits each. The device’s cascadable feature allows up to 8 devices to share a common 2-wire bus. The device is optimized for use in many industrial and commercial applications where low power and low voltage operation are essential. The AT24C32A/64A is available in space saving 8-lead JEDEC PDIP, 8-lead JEDEC SOIC, 8-lead EIAJ SOIC, 8-lead MAP and 8-lead TSSOP packages and is accessed via a 2-wire serial interface. In addition, the entire family isavailable in 2.7V 2.7V to 5.5V and 1.8V

1.8V to 5.5V versions.
