DS2502P-UNW

The DS2502P-UNW is designed as a uniqueware add-only memory. It differs from the regular devices in its custom ROM family codes and the uniqueware identifier 5E7 in plasce of the upper 12 bits of the standard serialization field.

DS2502P-UNW has eleven features. (1)1024 bits electrically programmable read only memory (EPROM) communicates with the economy of one signal plus ground. (2)Unique, factory-lasered and tested 64-bit registration number assures absolute traceability because no two parts are alike. (3)Built-in multidrop controller ensures compatibility with other microLAN products. (4)EPROM partitianed into 256-bit pages for randomly accessing packetized data records. (5)Each memory page can be permanently write-protected to prevent tampering. (6)Device is an "add only" memory where additional data can be programmed into EPROM without disturbing existing data. (7)Reduces control, address, data, power and programming signals to a single pin. (8)Directly connects to a single port pin of a microprocessor and communicated at up to 16.3Kbits per second. (9)Presence detector acknowledges when reader first applies voltage. (10)Low cost TO-92/PR-35 or 8-pin SOIC and TSOC surface mount packages. (11)Reads over a wide voltage range of 2.8V to 6.0V from -40°C to 85°C. Those are all the main features.

The uniqueware add-only memories DS2502P-UNW 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 the three memory pages available for programming in the application. Its memory size would be 1024 bits (4 pages). Its family code would be 89h. Its package is 6-pin TSOC package. And so on. At present we have not got so much information about this IC and we would try hard to get more information about it.
