24AA64/24LC64 2 64K I C Serial EEPROM Device Selection Table Description: Part VCC Max. Clock Temp. The Microchip Technology Inc. 24AA64/24LC64 Number Range Frequency Ranges (24XX64*) is a 64 Kbit Electrically Erasable PROM. The device is organized as a single block of 8K x 8-bit (1) 24AA64 1.8-5.5 400 kHz I memory with a 2-wire serial interface. Low-voltage 24LC64 2.5-5.5 400 kHz I, E design permits operation down to 1.8V, with standby Note 1: 100 kHz for VCC <2.5V and active currents of only 1 A and 1mA, respectively. It has been developed for advanced, low- power applications such as personal communications Features: or data acquisition. The 24XX64 also has a page write Single-supply with operation down to 1.8V capability for up to 32 bytes of data. Functional address Low-power CMOS technology: lines allow up to eight devices on the same bus, for up to 512 Kbits address space. The 24XX64 is available in - 1 mA active current, typical the standard 8-pin PDIP, surface mount SOIC, TSSOP -1 A standby current (max.) (I-temp) and MSOP packages.
