4096 bits Electrically Erasable Programmable
Read-Only Memory (EEPROM)
Unique, factory-lasered and tested 64-bit
registration number (8-bit family code + 48-
bit serial number + 8-bit CRC tester) assures
absolute identity because no two parts are
alike
Built-in multidrop controller ensures
compatibility with other MicroLAN鈩?/div>
products
Memory partitioned into sixteen 256-bit pages
for packetizing data
256-bit scratchpad with strict read/write
protocols ensures integrity of data transfer
Reduces control, address, data, and power to a
single data pin
Directly connects to a single port pin of a
microprocessor and communicates at up to
16.3kbps
Overdrive mode boosts communication speed
to 142kps
8-bit family code specifies DS2433
communication requirements to reader
Presence detector acknowledges when reader
first applies voltage
Low cost PR-35 or 8-pin SO surface mount
package
Reads and writes over a wide voltage range of
2.8V to 6.0V from -40擄C to +85擄C
