DS2430A+

The DS2430A+ is a 256-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 DS2430A 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 (14h) plus 256 bits of user-programmable EEPROM and a 64-bit one-time programmable application register. The power to read and write the DS2430A is derived entirely from the 1-Wire communication line. Data is transferred serially via the 1-Wire protocol, which requires only a single data lead and a ground return. The 48-bit serial number that is factory-lasered into each DS2430A provides a guaranteed unique identity that allows for absolute traceability.

• Built-in multidrop controller ensures compatibility with other MicroLAN products
• EEPROM organized as one page of 32 bytes for random access
• Reduces control, address, data and power to a single data pin
• 8-bit Family code specifies DS2430A communication requirements to reader
• Presence detector acknowledges when the reader first applies voltage
