25LC1024-I/SM

The 25LC1024-I/SM is a 1Mbit serial SPI bus EEPROM (Electrically Erasable Programmable Memory) in 8 pin SOIJ package. It features page, sector and chip erase functions typically associated with flash based products. These functions are not required for byte or page write operations. The memory is accessed via a simple Serial Peripheral Interface (SPI) compatible serial bus. The bus signals required are clock input (SCK), separate data in (SI) and data out (SO) lines. Access to the device is controlled by chip select input. Communication to the device can be paused via hold pin. While the device is paused, transitions on its inputs will be ignored with exception of chip select allowing host to service higher priority interrupts. It features more than 1 million erase/write cycles and data retention is greater than 200 years.
