DESCRIPTION
The Microchip Technology Inc. 24AA65 is a 鈥渟mart鈥?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 鏗俥xibility through the use of many
new user-programmable features. It is capable of oper-
ation down to 1.8V, the end-of-life voltage for 2 鈥淎A鈥?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 capacity of eight pages, or 64 bytes. This device
also features programmable security options for E/W
protection of critical data and/or code of up to 鏗乫teen 4K
blocks. Functional address lines allow the connection of

up to eight 24LC65's on the same bus for up to 512K bits
contiguous EEPROM memory. Advanced CMOS tech-
nology makes this device ideal for low-power non-vola-
tile code and data applications. The 24AA65 is available
in the standard 8-pin plastic DIP and 8-pin surface
mount SOIC package.
