Vue d'ensemble

Description

The 24LC02BT-I/SN is a 2 Kbit (256 x 8) electrically erasable programmable read-only memory (EEPROM) chip manufactured by Microchip Technology. It operates via the I²C (Inter-Integrated Circuit) interface, allowing up to 8 devices on the same bus with unique addresses. The device supports a wide voltage range of 1.7V to 5.5V, making it suitable for various applications, including portable electronics and battery-powered devices.
Key features include a page write capability (up to 16 bytes at once), fast write cycles (typically 5 ms), and low-power consumption, both during operation and standby. It is designed for data retention of up to 100 years, with a write endurance of 1 million cycles per byte.
The 24LC02BT-I/SN is commonly used in applications such as configuration settings, calibration data storage, and any situation where non-volatile memory is required. Its compact size and efficient performance make it a popular choice for developers in embedded systems and consumer electronics.

7. Packages: Available in various packages including SOIC, TSSOP, and DFN for diverse applications.
This combination of features makes the 24LC02BT-I/SN suitable for applications in consumer electronics, automotive, and industrial systems.

Package

The 24LC02BT-I/SN is available in an 8-pin MSOP (Micro Small Outline Package) and an 8-pin PDIP (Plastic Dual In-Line Package). These package types are designed for ease of integration into various electronic circuits.

Pinout

The 24LC02BT-I/SN is an I2C EEPROM (Electrically Erasable Programmable Read-Only Memory) with a pin count of 8.
Pin Functions:
1. VCC (Pin 1): Power supply (typically +2.5V to +5.5V).
2. GND (Pin 2): Ground reference.
3. SDA (Pin 3): Serial Data Line for data transmission.
4. SCL (Pin 4): Serial Clock Line for synchronization of the data transfer.
5. WP (Pin 5): Write Protect pin; when connected to VCC, it disables write operations.
6. A0 (Pin 6): Slave address select pin; can be connected to GND or VCC to differentiate multiple devices on the bus.
7. A1 (Pin 7): Another slave address select pin, similar to A0.
8. NC (Pin 8): No connection; not used in the circuit.
This device is commonly used for data storage applications in embedded systems.
