The AT25040-10PI is a 4Kbit serial EEPROM memory device from Quarktwin Technology Ltd., designed for applications requiring low power and low voltage operation. It operates over a voltage range of 2.7V to 5.5V and supports SPI communication in modes 0 and 3. The device features a maximum clock rate of 2.1 MHz and includes an 8-byte page mode for efficient data writing. Data protection is ensured through block write protection, which allows for the protection of 1/4, 1/2, or the entire memory array. The device also includes a write protect (WP) pin and self-timed write cycles with a maximum duration of 10 ms. With an endurance of 1 million write cycles and a data retention period of up to 100 years, the AT25040-10PI is suitable for industrial applications. It is available in both 8-pin PDIP and JEDEC SOIC packages, making it versatile for various design requirements.
