Description:
The Microchip Technology Inc. 24AA64/24LC64/
24FC64 (24XX64*) is a 64 Kbit Electrically Erasable
PROM. The device is organized as a single block of 8K
x 8-bit memory with a 2-wire serial interface. Low-volt-
age design permits operation down to 1.7V, with
standby and active currents of only 1 μA and 3 mA,
respectively. It has been developed for advanced, low-
power applications such as personal communications
or data acquisition. The 24XX64 also has a page write
capability for up to 32 bytes of data. Functional address
lines allow up to eight devices on the same bus, for up
to 512 Kbits address space. The 24XX64 is available in
the standard 8-pin PDIP, surface mount SOIC, TSSOP,
DFN, TDFN and MSOP packages. The 24XX64 is also
available in the 5-lead SOT-23, and Chip Scale
packages.
