产品介绍 FEATURES
1024 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 four 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 kbits per second 8-bit family code specifies DS2502 communications requirements to reader Presence detector acknowledges when the reader first applies voltage Low cost TO-92 or 8-pin SO, SOT-23 (3-pin), TSOC and flip chip surface mount package Reads over a wide voltage range of 2.8V to 6.0V from -40°C to +85°C; programs at 11.5V to 12.0V from -40°C to +50°C |
