MICROCHIP 1Kbit Serial Microwire EEPROM SOIC-8
Low-power 1Kbit serial EEPROM with Microwire interface. 1M cycles, >200yr retention, 2.5-5.5V, SOIC-8 package.
The MICROCHIP 1Kbit Serial Microwire EEPROM is a reliable, non-volatile memory solution designed for low-power applications. Built on advanced low-power CMOS technology, it ensures efficient operation with minimal energy consumption, making it ideal for battery-powered devices. The chip features self-timed erase and write cycles, simplifying the programming process and enhancing overall system reliability.
Key functionalities include automatic erase-all (ERAL) before write-all (WRAL) operations, providing robust data management. Integrated power ON/OFF data protection circuitry safeguards stored information against corruption during voltage transitions. Communication is handled via the industry-standard 3-wire serial Microwire interface, offering a simple and efficient connection to microcontrollers.
