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 capability
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 SOIC
packages.
