Transition Guide: Replacing the DS2430A with the DS2431
The DS2431 is an advanced 1-Wire 1k-bit EEPROM replacement device for the older 256-bit DS2430A. This guide discusses the differences in the command structure and memory map of the two devices. Particular attention is given to changes needed for applications that are transitioning to the larger DS2431 device. The guide also describes other important differences between the devices, specifically the DS2430A’s Application Register and how to use the DS2431 in a write-protected, simulated EPROM mode.
