DS2430A+ - EEPROM ser 1-Wire 256b TO92

The DS2430A is a 256-bit 1-Wire EEPROM. Like all 1-Wire devices, the DS2430A contains a factory-lasered 64-bit registration number that consists of a unique 48-bit serial number, an 8-bit CRC, and an 8-bit family code (14h). The DS2430A also provides 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.

Key Features

* 256-bit electrically erasable programmable read only memory (EEPROM) plus 64-bit one-time programmable application register

* Unique, factory-lasered and tested 64-bit registration number assures absolute identity because no two parts are alike

* Built-in multidrop controller ensures compatibility with other 1-Wire products

* EEPROM organized as one page of 32 bytes for random access

* Reduces control, address, data, and power to a single data pin

* Low-cost TO-92, 6-pin TSOC, or flip-chip packages

* Reads and writes over a wide voltage range of 2.8V to 6.0V from -40°C to +85°C
