FAQs
What is DS2502+?
The DS2502+ is a 1-Wire memory device manufactured by Maxim Integrated. It is used for secure data storage and identification in applications such as authentication, asset tracking, and electronic calibration. The device features unique factory-programmed 64-bit ROM for electronic serial number (ESN) and 1Kb of user-programmable EEPROM, which can be used to store calibration or configuration data.
How Does DS2502+ Work?
The DS2502+ utilizes Maxim's 1-Wire communication protocol, allowing it to be powered and communicate over a single data line. It can be accessed using simple serial commands to read from or write to the EEPROM, and to read the unique ESN. The device provides a robust and secure method for storing and retrieving data in a wide range of applications.
How Many Pins does DS2502+ have and What are the Functions of the Pinout Configuration?
The DS2502+ is housed in a 6-pin TSOC (Thin Small-Outline Package) package. The pinout configuration includes:
- 1-Wire: Data and power pin for the 1-Wire communication protocol.
- GND: Ground pin.
- NC: No connect pin (not internally connected).
- NC: No connect pin (not internally connected).
- NC: No connect pin (not internally connected).
- NC: No connect pin (not internally connected).
What are the Pros and Cons of DS2502+?
Pros:
- 1-Wire Interface: Simplifies connectivity and power for applications with a single data line.
- Secure Memory: Provides secure ESN and user-programmable EEPROM for data storage and identification.
- Robust Communication: Robust and reliable communication over long distances and in noisy environments.
- Easy Integration: Can be easily integrated into existing systems using simple serial commands.
Cons:
- Low Capacity: Limited EEPROM capacity for applications requiring larger data storage.
- Package Size: The 6-pin TSOC package may be relatively larger compared to other memory devices with similar capacity.
Are There Any Equivalents/Alternatives to DS2502+ for Recommendation?
- The DS2502-E48+ from Maxim Integrated is a similar device with extended temperature range.
- Alternatives to the DS2502+ include the DS28E02-100 from Maxim Integrated and the DS2434 from Maxim Integrated.
