詳細說明
iButton DESCRIPTIONThe DS1973 4Kb EEPROM iButton is a rugged read/write data carrier that identifies and stores relevant information about the product or person to which it is attached. This information can be accessed with minimal hardware, for example a single port pin of a micro-controller. The DS1973 consists of a factory lasered registration number that includes a unique 48-bit serial number, an 8-bit CRC, and an 8-bit Family Code (23H) plus 4096 bits of EEPROM. The power to program and read the DS1973 is derived entirely from the 1-Wire communication line. The memory is organized as sixteen pages of 256 bits each.SPECIAL FEATURES 4096 bits Electrically Erasable Programmable Read Only Memory (EEPROM) Overdrive mode boosts communication speed to 142kbps 256-bit scratchpad ensures integrity of data transfer Memory partitioned into 256-bit pages for packetizing data Reduces control, address, data and power to a single data pin 8-bit family code specifies DS1973 communication requirements to reader Reads and writes over a wide voltage range of 2.8V to 6.0V from -40°C to +85°C

常見問題解答
What is DS1973?
The DS1973 is a 4Kb iButton® that combines a 4Kb electrically erasable programmable read-only memory (EEPROM) with a 64-bit unique serial number and a real-time clock (RTC) in a rugged, self-contained package. It is designed for applications requiring secure data logging, time-stamping, and durable data storage in harsh environments.
How Does DS1973 Work?
The DS1973 works by integrating a 4Kb EEPROM for data storage, a 64-bit unique serial number for identification, and an RTC for time-keeping. The iButton® package provides protection against environmental and mechanical stress, making it suitable for challenging applications in industries such as manufacturing, logistics, and agriculture.
How Many Pins does DS1973 have and What are the Functions of the Pinout Configuration?
The DS1973 is housed in a 2-contact package within a stainless steel can. The pinout configuration includes:
- VCC: Power supply pin.
- GND: Ground pin.
What are the Pros and Cons of DS1973?
Pros:
- Rugged Design: The stainless steel iButton® package provides durability and resistance to harsh environments.
- Secure Data Storage: Includes a 4Kb EEPROM for secure, non-volatile data storage.
- Unique Serial Number: Provides a 64-bit unique serial number for easy identification and tracking.
- Real-Time Clock: Integrated RTC for accurate time-stamping and time-keeping.
- Portable Form Factor: The small iButton® form factor enables easy integration into various systems and equipment.
Cons:
- Limited Memory Capacity: The 4Kb EEPROM may have limited data storage capacity for certain applications.
- Single-Wire Interface: The single-wire interface may require specific protocols for communication and data retrieval.
Are There Any Equivalents/Alternatives to DS1973 for Recommendation?
The DS1973 is a unique iButton® device combining non-volatile memory and an RTC. Alternatives with similar features may include the DS1921G from Maxim Integrated, which integrates temperature monitoring along with data logging capabilities.
