24AA65/24LC65/

24C65 (24XX65)* 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 flexibility through the use of many new user-pro-

grammable features. The 24XX65 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

ensured. The 24XX65 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 24XX65'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 24XX65 is available in the standard

8-pin plastic DIP and 8-pin surface mount SOIC

package.
