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.

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 (1.7V 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.
