AT25256B-SSHL-B – ATMEL

The AT25256B-SSHL-B is a 256-kilobit (32,768 x 8) Serial Peripheral Interface (SPI) Electrically Erasable Programmable Read-Only Memory (EEPROM) integrated circuit manufactured by ATMEL. This device operates as a slave device on the SPI bus, supporting modes 0 (CPOL=0, CPHA=0) and 3 (CPOL=1, CPHA=1) for serial communication. The memory array is organized into 32,768 bytes, addressable via the SPI serial interface. The SSHL suffix designates the package type as an 8-lead Small Outline Integrated Circuit (SOIC) with a narrow body. The device requires a single power supply, with the ‘B’ denoting a specific voltage range and operational characteristics as defined in the manufacturer’s datasheet. It features a self-timed write cycle, typically 5ms, and supports sequential read operations for efficient data transfer. The AT25256B-SSHL-B is suitable for applications requiring non-volatile memory storage with a serial interface, such as configuration data storage, parameter storage, and data logging.
