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.
