24LC16BT-I/MC

24LC16BT-I/MC is a 16-kilobit I2C Serial EEPROM from Microchip. It provides non-volatile storage (2048 bytes) that retains data when power is removed, ideal for configuration data, calibration tables, and small look‑ups.
Key points:
- Interface and organization: I2C serial bus (two-wire), 2048 x 8 memory; supports random byte reads and sequential reads; 16-byte page writes.
- Addressing: 7-bit I2C address starts with 1010, plus three hardware address pins (A2–A0) to allow multiple devices on the same bus.
- Write protection: WP pin for block write protection.
- Voltage and timing: Supply typically 2.5–5.5 V; fast-mode I2C up to 400 kHz; write cycle time on the order of a few milliseconds.
- Endurance and data retention: ~1,000,000 write cycles; data retention measured in decades.
- Temperature and packaging: Industrial temperature range (-40 to +85 C); available in 8-pin packages (DIP/SOIC/TSSOP variants).
Common uses: small, reliably stored data that must survive power-down, such as device configuration, calibration constants, and firmware parameter storage.

8-pin package, typically an SOIC-8 (8‑pin Small Outline). The device is offered in other 8‑pin options as well (DIP-8, MSOP-8) per the datasheet.

- Pin count: 8 pins.
- Function: 16-Kbit I2C serial EEPROM (2K × 8) with I2C interface (SDA/SCL), 3 address pins (A0–A2) for device addressing, and a WP (write protect) pin, plus Vcc and GND.

- Manufacturer: Microchip Technology Inc.
- What kind of company: An American multinational semiconductor company that designs and manufactures microcontrollers, serial EEPROMs (like the 24LC16B family), memory products, and analog ICs. Headquarters in Chandler, Arizona.
