MICROCHIP 24LC32A 32Kbit I2C Serial EEPROM, 4K x 8, 400kHz, 8-pin DIP

The MICROCHIP 24LC32A-I/P is a 32Kbit I²C serial EEPROM, providing reliable, non-volatile memory storage organised as 4K x 8-bit. Its low-voltage design allows operation down to 1.7V, making it ideal for power-sensitive applications with standby and active currents of only 1mA.

This memory chip is engineered for advanced, low-power applications such as personal communications, data acquisition, and portable devices. It features a 32-byte page write buffer and a maximum page write time of 5ms, facilitating efficient data storage. The self-timed write cycle and hardware write-protect pin enhance data integrity and prevent accidental writes.

Key Features

• Utilises a 2-wire serial interface (I²C™ compatible) for simple integration.
• Schmitt trigger inputs suppress noise for reliable communication.
• Output slope control helps to eliminate ground bounce.
• Compatible with both 100kHz and 400kHz clock speeds.
• Offers exceptional endurance with over 1 million erase/write cycles.
• Provides long-term data retention, guaranteed for over 200 years.
• Includes ESD protection exceeding 4000V for ruggedness.
• Functional address lines allow up to eight devices on the same bus, supporting an address space of up to 256Kbit.

Supplied in a through-hole, 8-pin DIP package, it is designed for robust performance across an industrial temperature range from -40°C to 85°C, with a supply voltage range of 2.5V to 5.5V.
