概要

Description

The AT24C02BN-SH-T is a 2-kilobit (256 x 8-bit) EEPROM (Electrically Erasable Programmable Read-Only Memory) produced by Microchip Technology. It operates over an I2C interface, allowing multiple devices to communicate using just two wires (SDA and SCL). This EEPROM features a low-voltage operation range, typically from 1.8V to 5.5V, making it suitable for battery-operated devices.
Key features include:
- Memory Organization: 256 bytes of memory, organized into 32 pages of 8 bytes.
- Write Endurance: Supports over 1 million write cycles per byte.
- Data Retention: Can retain data for over 100 years.
- Packaging: Available in multiple packages, including SOIC and TSSOP.
- Applications: Commonly used in consumer electronics, automotive, and industrial applications for data storage and configuration settings.
Its small size, low power consumption, and reliability make it ideal for various embedded applications requiring non-volatile memory.

Features

The AT24C02BN-SH-T is a 2Kbit (256 x 8) I2C (Inter-Integrated Circuit) EEPROM (Electrically Erasable Programmable Read-Only Memory) from Microchip Technology. Key features include:
1. Memory Organization: 256 bytes of EEPROM, organized as 32 x 8 bits.
2. I2C Interface: Operates with a 2-wire I2C bus, supporting standard and fast modes (up to 400 kHz).
3. Byte and Page Write: Supports byte write operations and page writes (up to 16 bytes at a time).
4. Low Power Consumption: Consumes low active and standby current, making it suitable for battery-operated devices.
5. Operating Voltage: Functions over a voltage range of 1.8V to 5.5V.
6. Endurance: Capable of withstanding up to 1 million write/erase cycles and data retention of over 100 years.
7. Package Options: Available in various packages, including SOIC and TSSOP, for flexibility in design.
These features make the AT24C02BN-SH-T ideal for applications requiring reliable non-volatile memory storage, such as in consumer electronics, automotive, and industrial devices.
