AT24C02N** is a 2K-bit (256 x 8) serial Electrically Erasable Programmable Read-Only Memory (EEPROM) manufactured by **Atmel** (now part of Microchip Technology).

The AT24C02N is a 2K-bit (256 x 8) serial Electrically Erasable Programmable Read-Only Memory (EEPROM) manufactured by Atmel (now part of Microchip Technology).

Specifications:

  • Memory Size: 2Kbit (256 bytes)
  • Interface: I²C (Two-wire serial interface)
  • Operating Voltage: 1.8V to 5.5V
  • Write Cycle Time: 5ms (max)
  • Endurance: 1,000,000 write cycles
  • Data Retention: 100 years
  • Operating Temperature Range: -40°C to +85°C
  • Package Options: 8-pin PDIP, SOIC, TSSOP

Descriptions:

  • The AT24C02N is a low-power, byte-addressable EEPROM with a built-in hardware write-protect feature.
  • It supports I²C protocol with clock frequencies up to 400kHz (Fast-mode).
  • Features page write capability (up to 8 bytes per page).
  • Includes a write protect pin (WP) to prevent accidental writes.

Features:

  • Low Power Consumption:
  • Active Read Current: 1mA (typical)
  • Standby Current: 5μA (typical)
  • Schmitt Trigger Inputs for noise suppression.
  • Self-Timed Write Cycle with auto-clear.
  • A0, A1, A2 pins for device addressing (supports up to eight devices on the same bus).
  • Industrial Temperature Range (-40°C to +85°C).

The AT24C02N is commonly used in applications requiring non-volatile memory storage, such as consumer electronics, industrial systems, and automotive devices.
