The AT25040B is a 4Kbit Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) designed for low-power and low-voltage applications. It operates within a temperature range of -40°C to +85°C and supports a supply voltage from 1.8V to 5.5V. The device features a Serial Peripheral Interface (SPI) compatible 3-wire communication protocol, allowing for a clock frequency of up to 20MHz. This EEPROM is organized as 512 words of 8 bits each and includes an 8-byte page mode for efficient data writing. It offers robust data protection through block write protection, a write protect (WP) pin, and self-timed write cycles with a maximum duration of 5ms. The device has a high endurance rating of 1,000,000 write cycles and a data retention period of up to 100 years. The AT25040B is available in various package options, including JEDEC SOIC, UDFN, TSSOP, XDFN, and VFBGA, making it suitable for a wide range of industrial and commercial applications.
