Ranges
The Microchip Technology Inc. 24AA64/24LC64
(24XX64*) is a 64 Kbit Electrically Erasable PROM.
The device is organized as eight blocks of 1K x 8-bit
memory with a 2-wire serial interface. Low voltage
design permits operation down to 1.8V with standby
and active currents of only 1 碌A(chǔ) and 1 mA respectively.
It has been developed for advanced, low power appli-
cations such as personal communications or data
acquisition. The 24XX64 also has a page-write capabil-
ity 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
and MSOP packages.
