DS2433-Z01
4kbit 1-Wire EEPROM
www.maxim-ic.com
FEATURES
§ 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 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
16.3kbits per second
§ Overdrive mode boosts communication speed
to 142kbits per second
§ 8-bit family code specifies DS2433-Z01
communication requirements to reader
§ Presence detector acknowledges when reader
first applies voltage
§ Low-cost PR-35, 8-pin SO, or solder bumped
flip-chip package
§ Reads and writes over a wide voltage range of
2.8V to 6.0V from -40°C to +85°C
