DESCRIPTION
The Microchip Technology Inc. 24C65 is a “smart” 8K x
8 Serial Electrically Erasable PROM (EEPROM). 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. The
24C65 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 guar-
anteed. The 24C65 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 fifteen 4K blocks. Functional address lines allow
the connection of up to eight 24C65's on the same bus
for up to 512K bits contiguous EEPROM memory.
Advanced CMOS technology makes this device ideal
for low-power nonvolatile code and data applications.
The 24C65 is available in the standard 8-pin plastic DIP
and 8-pin surface mount SOIC package.
