EPROM partitioned into sixty-four 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
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 DS2505
communications requirements to reader
Presence detector acknowledges when the
reader first applies voltage
Low cost TO-92 or 6-pin TSOC 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
