Maxim Integrated DS2430AP+T&R EEPROM Memory Chip, 256bit, 2.8 → 5.25 V 6-Pin TSOC

1-Wire and iButton

The iButton is a computer chip enclosed in a 17mm diameter stainless steel can. Because of this unique and durable container, up-to-date information can travel with a person or object anywhere they go. It can be mounted anywhere because it is rugged enough to withstand harsh environments, indoors or outdoors. It is small and portable enough to attach to a key fob, ring, watch or other personal items. It can be used daily for applications such as access control to buildings and computers, asset management, and various data logging tasks.

The DS2430AP+T&R is a 256bit 1-wire EEPROM in 6 pin TSOC package. It identifies and stores relevant information about product to which it is associated. The DS2430A consists of factory lasered registration number that includes unique 48bit serial number, 8bit CRC, 8bit family code (14h) which specifies communication requirements to reader, 256bit of user programmable EEPROM and 64bit one time programmable application register. Data is transferred serially via 1-wire protocol which requires only single data lead and ground return. The 48bit serial number that is factory lasered into each DS2430A provides unique identity that allows for absolute traceability. The TSOC package provides a compact enclosure that allows standard assembly equipment to handle the device easily for attachment to printed circuit boards or wiring. Typical applications include storage of calibration constants, board identification and product revision status.
