4. Low Power Consumption: Designed for minimal power usage, suited for battery-powered applications.
5. Write Protection: Includes a write-protect pin to safeguard against accidental data overwrites.
6. Page Write: Supports page write capability of up to 16 bytes.
7. Endurance: 1,000,000 erase/write cycles, ensuring long-term reliability.
8. Data Retention: Over 200 years, providing robust data preservation.
9. High-Speed Operation: Up to 1 MHz clock frequency, allowing fast data transfer.
10. Temperature Range: Operates between -40°C to +85°C, suitable for industrial environments.
11. Package Options: Available in compact packages, such as SOT-23, for space-constrained designs.
These features make it suitable for applications requiring reliable non-volatile memory, such as data logging, configuration storage, and more.
Pinout
The pin functions are as follows:
1. VCC: Power supply voltage.
2. GND: Ground.
3. SDA: Serial Data - This pin functions as both input and output for the I2C bus. It is used to transfer data in and out of the device.
4. SCL: Serial Clock - This pin is used to synchronize data transfer over the I2C bus.
5. WP: Write-Protect - When connected to VCC, the write-protect function of the EEPROM is enabled, preventing any write operations. When connected to GND, the device operates normally and allows writing.
The 24AA04T-I/OT is designed for applications requiring data storage and retrieval, such as configuration data storage or small data logging tasks.
