Product Details

Description



Features:

1024 bits, 16 kbits or 64 kbits Electrically Programmable Read Only Memory (EPROM) communicates with the economy of one signal plus ground
Unique, factory-lasered and tested 64-bit registration number (8-bit family code, 36-bit serialization, 12-bit UniqueWare identifier 5E7H, 8-bit CRC-tester)     assures absolute traceability because no two parts are alike.
Built-in multidrop controller ensures compatibility with other MicroLAN products
EPROM partitioned into 256-bit pages for randomly accessing packetized data records
Each memory page can be permanently writeprotected to prevent tampering
Device is an "add only" memory where additional data can be programmed into EPROM without disturbing existing data
Reduces control, address, data, power and programming signals to a single pin
Directly connects to a single port pin of a microprocessor and communicates at up to 16.3k bits per second
Presence detector acknowledges when reader first applies voltage
Low cost TO-92/PR-35 or 8-pin SOIC and TSOC surface mount packages
Reads over a wide voltage range of 2.8V to 6.0V from -40°C to +85°C

Description

UniqueWare Add-Only Memories are factory programmed versions of the DS2502 (1024 bit), the DS2505 (16-kbit) and the DS2506 (64k bit) Add-Only Memories, respectively. They differ from the regular devices in their custom ROM family codes (see Ordering Information) and the UniqueWare Identifier 5E7 in place of the upper 12 bits of the standard serialization field. For technical details on the devices please refer to the DS2502, DS2505 and DS2506 data sheets.

UniqueWare Add-Only Memories DS2502 (1024 bit), the DS2505 (16-kbit) and the DS2506 (64k bit)  are only available preprogrammed with customer-specific and writeprotected 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, please refer to the UniqueWare Project Setup Manual, available as Application Note 99 from Dallas Semiconductor. The DS2502 (1024 bit), the DS2505 (16-kbit) and the DS2506 (64k bit)  UniqueWare Project Setup Software is available from the Dallas Semiconductor FTP Site at ftp://ftp.dalsemi.com/pub/auto_id, file name "unwsetup.exe."
