The Microchip Technology Inc. 24AA65 is a “smart” 8K x

8 Serial Electrically Erasable PROM. This device has

been developed for advanced, low power applications

such as personal communications, and provides the

systems designer with ﬂexibility through the use of many

new user-programmable features. It is capable of opera-

tion down to 1.8V, the end-of-life voltage for 2 “AA” bat-

tery cells for most popular battery technologies.The

24AA65 offers a relocatable 4K bit block of ultra-high-

endurance memory for data that changes frequently. The

remainder of the array, or 60K bits, is rated at 1,000,000

ERASE/WRITE (E/W) cycles guaranteed. The 24AA65

features an input cache for fast write loads with a capac-

ity of eight pages, or 64 bytes. This device also features

programmable security options for E/W protection of crit-

ical data and/or code of up to ﬁfteen 4K blocks. Func-

tional address lines allow the connection of up to eight

24LC65's on the same bus for up to 512K bits contigu-

ous EEPROM memory. Advanced CMOS technology

makes this device ideal for low-power non-volatile code

and data applications. The 24AA65 is available in the

standard 8-pin plastic DIP and 8-pin surface mount

SOIC package.
