DS2506S

Memory IC Overview

The DS2506S is a 64Kb Electrically Programmable Read-Only Memory (EPROM) utilizing the 1-Wire interface. It features a unique factory-lasered 64-bit registration number comprising an 8-bit family code, a 48-bit serial number, and an 8-bit CRC. The device includes 65536 bits of user-programmable EPROM data memory organized into 256 pages of 32 bytes each, alongside 2816 bits of EPROM status memory for write protection and page redirection. It operates on parasite power from the communication line during read operations at voltages between 2.8V and 6.0V, requiring 11.5V to 12.0V for programming.

Memory IC Feature Summary

• Supports add-only memory architecture allowing new data to be programmed without disturbing existing content
• Includes built-in multidrop controller ensuring compatibility with other MicroLAN products
• Provides hardware-level write protection for individual memory pages to prevent tampering
• Features page address redirection capability to allow software patching of invalid data records

Memory IC Applications

• Storage of calibration constants
• Maintenance record tracking
• Asset identification and tracking
• Product revision status logging
• Secure access code storage

Memory IC Procurement Notes

Verify the specific package suffix 'S' corresponds to the 8-pin SOIC surface mount configuration rather than the PR35 through-hole variant. Confirm that the ordering information matches the exact datasheet version required for your design. Ensure the procurement source provides documentation confirming the presence of the factory-lasered unique serial number and CRC values as specified in the product description.

Memory IC Selection Notes

Select this component when a compact, single-wire non-volatile memory solution is required for traceability and data integrity. The device is suitable for applications needing absolute uniqueness via its lasered serial number. Consider the parasite power requirement for read operations and the need for a 12V programming pulse if designing the host interface. Evaluate the 256-page structure against the total data volume needed for your specific application.

Memory IC Part Context

The DS2506 belongs to the Dallas Semiconductor 1-Wire family of devices designed for low-cost, high-reliability communication over a single data line. The 'S' suffix specifically denotes the 8-pin Small Outline Integrated Circuit (SOIC) package, distinguishing it from the PR35 plastic encapsulated transistor outline package. This part serves as a stand-alone database or identifier within MicroLAN networks.
