Product Introduction

AT24C02 is a 2048-bit serial EEPROM organized as 256 words × 8 bits (1 byte per word). Fabricated using a proprietary advanced CMOS process, it is suitable for low-power and low-voltage applications. The device is offered in standard 8-pin DIP, 8-pin SOP, 8-pin MSOP, 8-pin TSSOP, and 5-pin SOT-23/TSOT-23 packages. All read and write operations are handled via a standard 2-wire serial interface. The extended Vcc range of 1.8V to 5.5V makes it suitable for a wide range of applications.

Features

  • Low-voltage and low-power operation: AT24C02: VCC = 1.8V to 5.5V, industrial temperature range (-40°C to 85°C). AT24C02: 3-bit device address, suitable for all applications.
  • 16-byte page write mode.
  • Partial page write supported.
  • Internal organization: 256×8 (2K).
  • Standard 2-wire bidirectional serial interface.
  • Schmitt trigger inputs with noise suppression filtering.
  • Self-timed write cycle (5ms max).
  • 1 MHz (2.5–5V) and 400 kHz (1.8V) compatible.
  • Auto-erase before write operation.
  • Write protect pin for hardware data protection.
  • High reliability: 1,000,000 erase/write cycles typical endurance.
  • 100-year data retention.
  • Standard 8-pin DIP/SOP/MSOP/TSSOP and 5-pin SOT-23/TSOT-23 lead-free packages.
