DESCRIPTION
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 exibility 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 fteen 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.
