Description and Introduction

Two-wire Automotive Temperature Serial EEPROM The AT24C02B is a 2K-bit (256 x 8) serial electrically erasable and programmable read-only memory (EEPROM) manufactured by ATMEL (now part of Microchip Technology). Here are its key specifications:

- **Memory Organization**: 256 bytes (2K bits) organized as 256 x 8.
- **Interface**: I²C-compatible two-wire serial interface.
- **Operating Voltage**: 1.7V to 5.5V.
- **Clock Frequency**: Up to 400 kHz (I²C Fast Mode).
- **Write Cycle Time**: 5 ms maximum.
- **Write Endurance**: 1,000,000 write cycles.
- **Data Retention**: 100 years.
- **Page Write Buffer**: 8 bytes.
- **Operating Temperature Range**: -40°C to +85°C (industrial).
- **Package Options**: 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead TSSOP, and 5-lead SOT23.

The AT24C02B supports both random and sequential read modes and includes a write protect pin for hardware data protection. It is commonly used in applications requiring non-volatile memory storage.
