24LC16BT-I/MC

24LC16BT-I/MC is Microchip’s 16-kbit I2C serial EEPROM. Key points:
- Memory/organization: 2048 bytes (2K x 8), organized into 16-byte pages.
- Interface: I2C 2-wire bus (SDA, SCL) with 7-bit device address (1010 A2 A1 A0); A0–A2 pins allow up to eight devices on the same bus.
- Addressing: 16-bit memory address (MSB/LSB) required to address the full 2048 bytes.
- Features: random and sequential reads; page writes up to 16 bytes; write cycle ~5 ms; endurance ~1,000,000 write cycles; data retention > 200 years.
- Protection: Hardware Write-Protect (WP) pin to guard memory contents.
- Electrical: Supply voltage typically 2.5–5.5 V; I2C speeds up to standard and 400 kHz (Fast-mode).
- Packaging/Temp: 8-pin packages (DIP/SOIC); Industrial temperature range (-40°C to +85°C) for I-series variants.
- Applications: small data storage for MCUs—config data, calibration tables, lookup tables, logs.
In short, a compact, nonvolatile EEPROM for reliable, low-pin-count memory on I2C systems.
