DS2506S

• 64-Kbit Add-Only Memory
• Features
• 65536 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 hundred fifty six
• 256-bit pages for randomly accessing packetized
• data records
• Eack memory page can be permanently write-
• protected to prevent tampering
• Device is an "add only" memory where additional databe programmed into EPROM without disturbing existing data
• Architecture allows software to patch data by
• supersending 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
• Overdrive mode boosts communication speed
• to 142 kbits per second
• 8-bit family code specifies DS2506 communications
• requirements to reader
• Presence detector acknowledges when the reader
• first applies voltage
• Low cost PR35 or 8-pin SOIC 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
