The devices 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 AT24C64B is available in space saving 8-lead PDIP, 8-lead JEDEC SOIC and 8-lead TSSOP packages and is accessed via a 2-wire serial interface. In addition, the entire family is available in 2.7V (2.7 to 5.5V) and 1.8V (1.8 to 5.5V) versions. 8-lead SOIC 2-Wire, 32K Pin Configurations 2 Pin Name Function Serial E PROM A0 1 8 VCC A0 - A2 Address Inputs A1 2 7 WP A2 3 6 SCL SDA Serial Data GND 4 5 SDA SCL Serial Clock Input WP Write Protect 8-lead TSSOP 8-lead PDIP A0 1 8 VCC A0 1 8 VCC A1 2 7 WP A1 2 7 WP A2 3 6 SCL A2 3 6 SCL GND 4 5 SDA GND 4 5 SDA 3350DSEEPR05/05 1AT24C64B Absolute Maximum Ratings* *NOTICE: Stresses beyond those listed under Absolute Operating Temperature...................................... -55 to +125C Maximum Ratings may cause permanent dam- Storage Temperature ......................................... -65 to +150C age to the device.
