Microchip Serial EEPROM 64kB, 900 ns, 8-Pin PDIP, Serial-I2C, 24LC64-I/P

The Microchip 24LC64-I/P is a high-performance serial EEPROM designed for digital memory storage applications requiring non-volatile reliability and rapid access times. With a total memory size of 64kB, this EEPROM is suitable for use in industrial, instrumentation, automotive, and embedded electronics, where dependable data storage and easy interface are critical.

Based on CMOS technology, the device boasts an ultra-low maximum active current of just 3mA and a standby current as low as 1μA, enabling it to operate efficiently in energy-sensitive assemblies. It supports a supply voltage range from 2.5V to 5.5V and maintains data integrity with retention over two hundred years, making it especially useful in mission-critical environments.

The 24LC64-I/P utilizes a 2-wire Serial-I2C interface, allowing seamless integration with a wide range of microcontrollers, FPGAs, and digital control systems. This interface supports clock frequencies up to 400kHz, facilitating fast communication and data transfers across system buses. The EEPROM is organized as 8K x 8-bit words, granting flexibility for various data formats and storage schemes.

The device’s hardware includes Schmitt Trigger inputs for effective noise suppression, page write time of 5 ms, and self-timed erase/write cycles, optimizing reliability and minimizing the risk of data corruption in noisy or fluctuating environments. A standard 8-pin PDIP package with through-hole mounting offers robust physical connection and ease of installation in PCB assemblies.

Additional features include output slope control to eliminate ground bounce, compatibility with cascaded addressing up to eight devices, ESD protection beyond 4000V, and hardware write-protect functionality. Its operating temperature range is from -40°C to 85°C, enabling stable operation under varying industrial conditions.

The Microchip 24LC64-I/P finds applications in industrial automation, automotive control systems, laboratory equipment, embedded system design, commercial electronics, and memory backup in programmable devices. Its durability ensures more than one million erase/write cycles and reliability in extended deployments.
