24C02N EEPROM IC 2Kbits 1MHz I2C DIP-8

Description

24C02N EEPROM IC 2Kbits 1MHz I2C DIP-8 The 24C02N is a tiny, non-volatile serial EEPROM providing 2K-bit storage arranged as 256 × 8-bit words. It is implemented as a two-wire (I²C) memory device and is built to be compact and easy to integrate with microcontrollers. The device is optimized for low-power operation and is offered in common space-saving packages so it can be added to small boards or legacy through-hole designs. Memory is accessed through a two-wire serial protocol with standard start/stop, acknowledge and sequential read/write procedures. The device retains the last addressed location between operations, supports page writes, and implements acknowledge-polling to signal internal write completion. A hardware write-protect pin provides a simple way to prevent unwanted memory writes. The interface is designed to be interoperable with typical microcontroller I²C peripherals. The 24C02N is available in several package styles including an 8-lead DIP suitable for through-hole mounting, making it convenient for prototyping and repairable designs. Its small footprint, nonvolatile data retention, and simple serial interface make it suitable as a configuration, calibration or user-settings store on a wide range of electronic products. Ordering and packaging options are provided for both tube and reel shipment. Features: Wide voltage operation (VCC = 1.7V to 5.5V). Operating ambient temperature: −40°C to +85°C. Internally organized (24C02 = 256 × 8). Two-wire serial interface (I²C). Schmitt trigger, filtered inputs for noise suppression. Bidirectional data transfer protocol. 1 MHz (at 5V) and 400 kHz compatibility (at lower voltages). Write Protect pin for hardware data protection. 8-byte page write mode (for 2K device). Partial page writes allowed. Self-timed write cycle (max 5 ms). High reliability: 1 million write cycles; 100 years data retention.
