com TM DS2502/5/6-UNW Add-Only Memory SPECIAL 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 § Presen...
