概述

UniqueWare™ Add-Only Memories are factory programmed versions of the DS2502 (1024 bit), the DS2505 (16Kb) and the DS2506 (64Kb) Add-Only Memories, respectively. They differ from the regular devices in their custom ROM family codes and the UniqueWare Identifier 5E7 in place of the upper 12 bits of the standard 64-bit ROM serialization field. For technical details on the devices refer to the DS2502, DS2505 and DS2506 data sheets. UniqueWare add-only memories are only available preprogrammed with customer-specific and write protected data. UniqueWare data fills at least one but no more than the first four pages of a device, depending on the length of the customer-supplied data. This leaves up to three (DS2502-UNW), 63 (DS2505-UNW) or 255 (DS2506-UNW) memory pages available for programming in the application. For more details on UniqueWare and how to set up data files, refer to Application Note 99. The UniqueWare project setup software is available from the Dallas Semiconductor FTP site at http://files.dalsemi.com/auto_id/unwsetup.exe

关键特性

1kb, 16kb or 64kb Electrically Programmable Read Only Memory (EPROM) Unique, factory-lasered and tested 64-bit registration number assures absolute traceability because no two parts are alike. Built-in multidrop controller ensures compatibility with other 1-Wire products EPROM partitioned into 256-bit pages for randomly accessing packetized data records Each memory page can be permanently write protected to prevent tampering Reduces control, address, data, power and programming signals to a single pin Low cost TO-92/PR-35 or 8-pin SO and TSOC surface mount packages Reads over a wide voltage range of 2.8V to 6.0V from -40°C to +85°C
