Description

The Microchip Technology Inc. 24AA515/24LC515/

24FC515 (24XX515*) is a 64K x 8 (512K bit) Serial

Electrically Erasable PROM, capable of operation

across a broad voltage range (1.8V to 5.5V). It has

been developed for advanced, low power applications

such as personal communications or data acquisition.

This device has both byte write and page write capabil-

ity of up to 64 bytes of data. This device is capable of

both random and sequential reads. Reads may be

sequential within address boundaries 0000h to 7FFFh

& 8000h to FFFFh. Functional address lines allow up to

four devices on the same data bus. This allows for up

to 2 Mbits total system EEPROM memory. This device

is available in the standard 8-pin plastic DIP and SOIC

packages.
