DS9093RA+ - Brand New Maxim Integrated Accessories
-
Description
The DS1982 1Kb Add-Only iButton is an electronic component model belonging to the category of accessories. It is a read/write data carrier integrated circuit that stores and identifies relevant information about the product or object it is attached to. A microcontroller can access this information with minimal hardware. The DS1982 consists of a unique 48-bit serial number and is derived entirely from the 1-Wire communication line. The device can be programmed and then write-protected if desired, or programmed multiple times with new data appended to, but not overwriting, existing data with each subsequent programming of the device.
Specifications and features
- 1024 bits Electrically Programmable Read-Only Memory (EPROM) communicates with the economy of one signal plus ground
- EPROM partitioned into four 256-bit pages for randomly accessing packetized data
- Each memory page can be permanently write-protected to prevent tampering
- Device is an “add-only” memory where additional data can be programmed into EPROM without disturbing existing data
- Architecture allows software to patch data by superseding an old page in favor of a newly programmed page
- Reduces control, address, data, power, and programming signals to a single data pin
- 8-bit family code specifies DS1982 communications requirements to the reader
- Reads over a wide voltage range of 2.8V to 6.0V from -40°C to +85°C; programs at 11.5V to 12.0V from -40°C to +50°C
- Unique, factory-lasered, and tested 64-bit registration number (8-bit family code + 48-bit serial number + 8-bit CRC tester) assures absolute traceability because no two parts are alike
- Multidrop controller for MicroLAN
- Digital identification and information by momentary contact
- Chip-based data carrier compactly stores information
- Data can be accessed while affixed to the object
- Economically communicates to the bus master with a single digital signal at 16.3kbps
- Standard 16mm diameter and 1-Wire® protocol ensure compatibility with iButton® family
- Button shape is self-aligning with cup-shaped probes
- Durable stainless steel case engraved with registration number, withstands harsh environments
- Easily affixed with self-stick adhesive backing, latched by its flange, or locked with a ring pressed onto its rim
- Presence detector acknowledges when the reader first applies voltage
Application Scenarios
The DS1982 1Kb Add-Only iButton is widely used in commercial and industrial scenarios where a reliable and rugged data carrier is needed to store information about the product or object it is attached to.
Comparison
Advantages- Compact size and rugged construction make it ideal for harsh environments
- Single pin communication protocol simplifies the microcontroller's hardware design, reducing cost and complexity
- EPROM partitioned into four 256-bit pages that allow for randomly accessing packetized data without disturbing previously stored data
- Can be easily affixed with self-stick adhesive backing, latched by its flange, or locked with a ring pressed onto its rim
Disadvantages- The device has a limited storage capacity of 1Kb, which may not be sufficient for some applications requiring more data storage space
- The device can only be programmed and read through the 1-Wire communication line, which may limit its compatibility with some systems
- The device is an “add-only” memory, which means that it cannot overwrite existing data and may require additional programming steps to update the stored information
