Product Summary

The DS2433 is a 4k-bit 1-wire EEPROM. 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 of the DS2433+ 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.

Parametrics

DS2433 absolute maximum ratings: (1)Voltage on Any Pin Relative to Ground: -0.5V to +7.0V; (2)Operating Temperature: -40℃ to +85℃; (3)Storage Temperature: -55℃ to +125℃; (4)Soldering Temperature: 260℃ for 10 seconds.

Features

DS2433 features: (1)Built-in multidrop controller ensures compatibility with other MicroLAN products; (2)Memory partitioned into sixteen 256-bit pages for packetizing data; (3)256-bit scratchpad with strict read/write protocols ensures integrity of data transfer; (4)Reduces control, address, data and power to a single data pin; (5)Directly connects to a single port pin of a microprocessor and communicates at up to 16.3k bits per second; (6)Overdrive mode boosts communication speed to 142k bits per second; (7)8-bit family code specifies DS2433 communication requirements to reader.
