DESCRIPTION
The Microchip Technology Inc. 24LC65 is a 鈥渟mart鈥?8K
x 8 Serial Electrically Erasable PROM. This device
has been developed for advanced, low power applica-
tions such as personal communications, and provides
the systems designer with 铿俥xibility through the use of
many new user-programmable features. The 24LC65
offers a relocatable 4K bit block of ultra-high-endurance
memory for data that changes frequently. The remain-
der of the array, or 60K bits, is rated at 1,000,000
ERASE/WRITE (E/W) cycles guaranteed. The 24LC65
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 protec-
tion of critical data and/or code of up to 铿乫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
technology makes this device ideal for low-power non-
volatile code and data applications. The 24LC65 is
available in the standard 8-pin plastic DIP and 8-pin
surface mount SOIC package.
