Microchip Technology, Inc. 1Mb I2C compatible 2-wire Serial EEPROM with 1MHz clock compatibility en024639

The Microchip Technology Inc. 24FC1025 is a1024Kb (128K x 8) Serial Electrically Erasable PROM (EEPROM), 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 128 bytes of data. This device is capable of both random and sequential reads. Reads may be sequential within address boundaries 0000h to FFFFh and 10000h to 1FFFFh. Functional address lines allow up to four devices on the same data bus. This allows for up to 4 Mbits total system EEPROM memory. This device is available in the standard 8-pin PDIP and SOIJ packages. Additional Features Reliable EEPROM Memory 128K x 8 (1024 Kbit) 128-Byte Page Write Buffer Page Write Time 5 ms Max.
