The DS24B33 is a 4096-bit, 1-Wire® EEPROM organized as 16 memory pages of 256 bits each. Data is written to a 32-byte scratchpad, verified, and then copied to the EEPROM memory. The DS24B33 communicates over a single-conductor 1-Wire bus. The communication follows the standard 1-Wire protocol. Each device has its own unalterable and unique 64-bit registration number that is factory programmed into the chip. The registration number is used to address the device in a multidrop 1-Wire net environment. The DS24B33 is software compatible to the DS2433.
Applications
- Board Identification
- Medical Sensor Calibration Data Storage
- Smart Cables
- Storage of Calibration Constants
- Storage of Product Revision Status

Evaluation Kits 4
DS9090EVKIT
1-Wire Device Evaluation Kit
Features and Benefits
- Easy Setup with USB Adapter
- Fully Compliant with USB 2.0 Specification
- Software Runs on Windows 8, Windows 7, WindowsVista®, and Windows XP® OS (32-Bit and 64-Bit Versions)
- Convenient On-Board Test Points and Dual TO92 Socket
- Standard RJ11 Connector Interfaces to DS9120 Socket Boards
- Free Download of 1-Wire Drivers and OneWireViewer Demonstration Software
- Compatible with Other 1-Wire Devices Purchased Separately
Product Detail
The DS9090EVKIT evaluation system (EV system) consists of a DS9490+ USB-to-1-Wire®/iButton® adapter for PC connectivity, a DS9120P+ socket board with RJ11 cable, and seven different 1-Wire devices. This EV system provides the special hardware and software system to exercise the features of 1-Wire devices with memory or PIO/switches, except 1-Wire EPROM devices. (EPROM devices such as the DS2502 and DS2506 require a different adapter (DS9481R-3C7) to perform an EPROM write. This adapter can be purchased separately.) 1-Wire EPROM devices are available for sampling.
The EV system software consists of the OneWireViewer (a Java® program) that runs under Windows ® OS and comes as part of the 1-Wire drivers installation package.
DS9120P
Socket Boards for Evaluating 1-Wire Devices
Product Detail
The DS9120 family of socket boards are RJ11-to-socket boards that provide the hardware connectivity necessary to evaluate and operate 1-Wire® products in an easy-to-use PC environment. Additionally, the socket boards can be readily used with the DS9481R USB-to1-Wire adapter to create a 1-Wire PC programmer for 1-Wire EEPROM and one-time programmable (OTP)/EPROM devices.
