The Microchip Technology 24LC21-I/P is a 1Kbit Electrically Erasable PROM (EEPROM) with a 128 x 8 bit organization. This device is designed for applications that require the storage and serial transmission of configuration and control information. It supports a 2-wire serial interface bus compatible with I2C™ standards and operates with a single supply voltage ranging from 2.5V to 5.5V.
The 24LC21-I/P offers a clock frequency compatibility of 100 kHz at 2.5V and 400 kHz at 5V, with an access time of 900 ns. It features low-power CMOS technology, consuming approximately 1 mA during active operation and 10 µA in standby mode at 5.5V. The device includes a self-timed write cycle with auto-erase and a page-write buffer capable of holding up to 8 bytes.
This EEPROM is available in an 8-pin PDIP package and is suitable for industrial temperature ranges from -40°C to +85°C. It ensures 1,000,000 erase/write cycles and data retention exceeding 200 years, making it a reliable choice for long-term data storage.
The device supports two modes of operation: Transmit-only mode upon power-up, sending the entire memory array contents serially, and Bidirectional mode, which allows for byte-selectable read/write capability after a valid high-to-low transition on the SCL pin.
