DESCRIPTION
The Microchip Technology Inc. 24FC65 is a “smart”
8K 8x 8 Serial Electrically Erasable PROM (EEPROM)
with a high-speed 1MHz SE2.bus whose protocol is
functionally equivalent to the industry-standard I2C
bus. This device has been developed for advanced
applications such as personal communications, and
provides the systems designer with flexibility through
the use of many new user-programmable features. The
24FC65 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 24FC65 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
