Description
Equivalent
1. DS28EC20 - Another 1-Wire EEPROM from Maxim Integrated (Analog Devices).
2. AT24Cxx series - I2C EEPROMs from Microchip, offering similar storage options.
3. 24AAxx/24LCxx series - I2C EEPROMs also from Microchip.
While the communication protocols differ (1-Wire vs. I2C), these products offer similar functionalities in terms of EEPROM storage capabilities. Ensure compatibility with your specific application requirements.
Features
1. Memory Capacity: The DS2505+ provides 64Kb (8KB) of non-volatile EPROM memory, organized as 256 pages of 32 bytes each.
2. 1-Wire Interface: Utilizes a single communication line for data transfer and power, simplifying connections and reducing wiring complexity.
3. Unique 64-bit Serial Number: Each device has a unique 64-bit registration number, allowing for easy device identification and addressing.
4. EPROM Technology: Being an EPROM, the memory is non-volatile and retains data even when powered off. Data can be written once and read multiple times.
5. Write Protection: Features programmable write protection for individual pages, enhancing data security.
6. Wide Operating Range: Operates in a voltage range typically between 2.8V to 6.0V, suitable for various applications.
7. Applications: Commonly used in scenarios requiring secure and reliable storage, like calibration data, security keys, or identification numbers in embedded systems.
These features make the DS2505+ suitable for applications requiring reliable and secure data storage with minimal interface wiring.
Pinout
1. Data (DQ): This pin serves as the 1-Wire data interface. It is used for both data input and output, allowing communication with the host controller over the 1-Wire protocol. The DQ pin is also used for powering the device parasitically.
2. Ground (GND): This pin is connected to the ground or 0V reference of the circuit.
3. NC (No Connect): This pin is not connected internally and is typically left unconnected in the circuit.
The DS2505+ is used for storing data such as identification, calibration, and configuration information. It supports features like write protection and can be powered directly through the data line, making it suitable for applications requiring minimal wiring.
