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
16.3k bits per second
§ Overdrive mode boosts communication speed
to 142k bits per second
§ 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 SOIC surface mount
package
§ Reads and writes over a wide voltage range of
2.8V to 6.0V from -40°C to +85°C

SILICON LABEL DESCRIPTION
The DS2433 4K-bit 1-Wire EEPROM identifies and stores relevant information about the product to
which it is associated. This lot or product specific information can be accessed with minimal interface,
for example a single port pin of a microcontroller. The DS2433 consists of a factory-lasered registration
number that includes a unique 48-bit serial number, an 8-bit CRC, and an 8-bit Family Code (23h) plus
4096 bits of user-programmable EEPROM. The power to read and write the DS2433 is derived entirely
