Description:
The Microchip Technology Inc. 24AA64F/24LC64F/
24FC64F (24XX64F*) 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-
voltage design permits operation down to 1.7V, with
standby and read currents of only 1 A and 400 A,
respectively. It has been developed for advanced, low-
power applications such as personal communications
or data acquisition. The 24XX64F 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 24XX64F
is available in the standard 8-pin PDIP, surface mount
SOIC, TSSOP, TDFN and MSOP packages. The
24XX64F is also available in the 5-lead SOT-23
package.
