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.

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
