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 24XX515 is used in this document as a generic part number packages. for the 24AA515/24LC515/24FC515 devices. 2003 Microchip Technology Inc.
