The device is organized as a single block of Note 1: 100 kHz for VCC <2.5V. 8K x 8-bit memory with a 2-wire serial interface. Low- 2: 400 kHz for VCC <2.5V. voltage design permits operation down to 1.7V, with standby and read currents of only 1 A and 400 A, Features: respectively. It has been developed for advanced, low- power applications such as personal communications Single-Supply with Operation down to 1.7V for or data acquisition. The 24XX64F also has a page 24AA64F/24FC64F Devices, 2.5V for 24LC64F Devices write capability for up to 32 bytes of data. Functional address lines allow up to eight devices on the same Low-Power CMOS Technology: bus, for up to 512 Kbits address space. The 24XX64F - Read current 400 A, max. is available in the standard 8-pin PDIP, surface mount - Standby current 1 A, max. (I-temp) SOIC, TSSOP, TDFN and MSOP packages. The 2 2-Wire Serial Interface, I C Compatible 24XX64F is also available in the 5-lead SOT-23 Packages with Three Address Pins are package.
