The Microchip Technology 25C040XT-I/ST is a 4 Kbit serial Electrically Erasable PROM (EEPROM) that utilizes a Serial Peripheral Interface (SPI) compatible serial bus for communication. This device offers a memory organization of 512 x 8 bits and supports a maximum clock frequency of 3 MHz.
Designed for reliable operation, the 25C040XT-I/ST operates within a voltage range of 4.5V to 5.5V and an industrial temperature range of -40°C to 85°C. Key features include a write cycle time of 5ms, built-in write protection circuitry, and high reliability with an endurance of 1M cycles and data retention exceeding 200 years.
This EEPROM is supplied in an 8-TSSOP package, suitable for surface mounting. The SPI interface requires clock (SCK), data in (SI), and data out (SO) lines, with device access controlled by a Chip Select (CS) input. Communication can be paused using the HOLD pin, and write operations can be disabled via the write-protect (WP) pin.
With its low power consumption, robust design, and standard SPI interface, the 25C040XT-I/ST is well-suited for various data storage applications in embedded systems.
