BC134

512 bits 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 + 48-bit serial number + 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 two 256-bit pages for randomly accessing packetized data

. Each memory page can be permanently write-protected to prevent tampering

. Device is an “add-only” memory where additional data can be programmed into EPROM without disturbing existing data

. Architecture allows software to patch data by superseding an old page in favor of a newly programmed page

. Reduces control, address, data, power, and programming signals to a single data pin

. Directly connects to a single port pin of a microprocessor and communicates at up to 16.3 kbps

. 8-bit family code specifies DS2501 communications requirements to reader
