Description

24AA024T-I/MNY is Microchip’s 2‑Kbit I2C serial EEPROM (256 x 8). It provides non-volatile storage for small data (device IDs, calibration data, configuration, etc.) with a low-pin, 8‑pin package.
Key points:
- Interface: I2C two-wire
- Memory: 256 bytes (2 Kbit)
- Voltage: 1.8–5.5 V
- Temperature: Industrial range (-40°C to +85°C) for the -I suffix
- Endurance/retention: >1,000,000 write cycles; data retention typically long (datasheet specifies specifics)
- Package: RoHS-compliant 8-pin device; -MNY denotes packaging/lead-free variant
Common uses: small, persistent storage in microcontroller-based projects (config tables, calibration data, IDs).
Note: Check the exact datasheet for pinout, addressing, page write size, and timing details. The -I indicates industrial temp range; -MNY indicates the packaging variant.
