DS2423 4kbit 1-Wire RAM With Counter

The DS2423 1-Wire RAM with Counters is a fully static, read/write memory for battery operation in a low-cost, six-lead TSOC, surface-mount package. The memory is organized as 16 pages of 256 bits each. In addition, the device has four Counters two of them with external trigger inputs called A and B. Each of the Counters is associated with a memory page. A Counter without external trigger input increments each time data is written to the page it is associated with (write cycle counter). The Counters triggered by inputs A and B, respectively, increment with every low-going pulse on their input. All Counters are read-only. They are automatically cleared to 0 when the battery is connected.
The battery-backed memory offers a simple solution to storing and retrieving information pertaining to the equipment where the DS2423 is installed and its frequency of use. The scratchpad is an additional page that acts as a Buffer when writing to memory. Data is first written to the scratchpad where it may be read back for verification. A copy scratchpad command will then transfer the data to memory. This process ensures data integrity when modifying the memory. A 64-bit registration number is factory lasered into each DS2423 to provide a guaranteed unique identity which allows for absolute traceability and acts as node address if multiple DS2423 are connected in parallel to form a local network. Data is transferred serially via the 1-Wire protocol, which requires only a single data lead and a ground return.
The DS2423 1-Wire RAM with Counters CAN store encrypted data. The unique registration number and the page write cycle counter(s) prevent unauthorized manipulation of data stored in a page with a write cycle Counter associated.
