Overview

Description

AT24C02B-TH-T is a Microchip/Atmel 2-kbit I2C serial EEPROM. It provides 256 bytes of non-volatile storage accessible over I2C.
Key points:
- Capacity: 256 x 8 bits (2 kbits total)
- Interface: I2C two-wire; device address 1010 A2 A1 A0; 7-bit base address 0x50 (A0–A2 are hardware pins)
- Memory organization: 1-byte memory addresses (256 locations)
- Page size: 8 bytes; can perform a page write within an 8-byte page
- Speed: standard 100 kHz and fast-mode 400 kHz I2C
- Write cycle: tWC ≈ 5 ms max
- Endurance/Data retention: ~1,000,000 write cycles; data retained ~100 years
- Voltage and temp: typically 1.7–5.5 V supply; -40°C to +85°C operating range
- Package: 8-pin through-hole (TH) variant; -TH-T indicates specific packaging (check datasheet for exact option)
Uses: small non-volatile storage for MCU configs, calibration data, logs, or look-up data.

Features

AT24C02B-TH-T features:
- 2 Kbit I2C serial EEPROM (256 × 8)
- I2C two-wire interface; A0–A2 address pins allow up to 8 devices on a bus
- 8-byte page write; random and sequential read capability
- Hardware write protection via WP pin
- Operating voltage: 1.7 V to 5.5 V
- I2C clock up to 400 kHz (Fast-mode)
- Endurance: typically 1,000,000 write cycles
- Data retention: typically up to 200 years
- Low power consumption; efficiently powers down in standby
- 8-pin package (TH variant commonly offered in standard packages)

Package

8-pin small‑outline package (SOIC/SOP‑8), in Tape‑and‑Reel packaging.

Pinout

- Pin count: 8 pins (DIP-8/SOP-8 package).
- Function: 2-kbit I2C serial EEPROM (256 x 8) for nonvolatile storage. Interface via I2C (SDA, SCL). Has address pins A0–A2 to set the device I2C address and a WP (write protect) pin. VCC and GND supply.

Manufacturer
