Overview
19-4892; Rev 8/09 SPECIAL FEATURES  16384 bits Electrically Programmable Read Only Memory (EPROM) communicates with the economy of one signal plus ground  EPROM partitioned into 64 256-bit pages for randomly accessing packetized data records  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  8-bit family code specifies DS1985 communications requirements to reader  Reads over a wide voltage range of 2.
