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 (1.7V 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 and 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 SOIJ packages.
