Microchip 24LC02B 2Kbit I2C Serial EEPROM, SOIC-8

The Microchip 24LC02B-I/SN is a 2Kbit serial I2C EEPROM (Electrically Erasable Programmable Read-Only Memory) housed in a compact 8-pin SOIC package. This low-density, non-volatile memory device is organised as a single block of 256 x 8-bit memory, utilising a reliable two-wire serial interface for simple integration into a wide range of electronic designs.

A key advantage of this IC is its exceptionally low power consumption. Its low-voltage design permits stable operation down to just 1.7V, with standby and active currents of only 1μA and 1mA respectively. This makes it perfectly suited for battery-powered and portable applications where power efficiency is paramount.

Key Features & Specifications

The device offers a page write capability for up to 8 bytes of data, streamlining programming operations. It supports a maximum clock frequency of 400KHz and operates across a broad supply voltage range of 2.5V to 5.5V. Built with low-power CMOS technology, it includes Schmitt trigger inputs for excellent noise suppression and output slope control to eliminate ground bounce.

Reliability and durability are central to its design. The self-timed erase/write cycle has a typical page write time of 3ms and is backed by a hardware write-protect pin. It is rated for more than 1 million erase/write cycles and offers greater than 200 years of data retention, ensuring long-term integrity of stored information. It operates reliably across an industrial temperature range of -40°C to +85°C.

Applications

This versatile EEPROM is ideal for numerous applications, including embedded system design and development, consumer electronics, and a wide array of portable devices where reliable, low-power, non-volatile memory storage is required.
