Description

The Microchip Technology Inc. 24AA65 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-programmable features. It is capable of opera-tion down to 1.8V, the end-of-life voltage for 2 "AA" 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 capac-ity of eight pages, or 64 bytes. This device also features programmable security options for E/W protection of crit-ical data and/or code of up to fifteen 4K blocks. Func-tional address lines allow the connection of up to eight 24LC65's on the same bus for up to 512K bits contigu-ous EEPROM memory.Advanced CMOS technology makes this device ideal for low-power non-volatile code and data applications. The 24AA65 is available in the standard 8-pin plastic DIP and 8-pin surface mount SOIC package.
