Design files

Overview

The focus of this design is the bidirectional communication across an isolation for loop powered applications. The challenge of such a solution is first of all the limited size within sensor transmitters and in case of a loop powered system the overall current consumption.

Features
  • Isolated single wire bi-directional data transmission
  • Bit rates up to 1Mbps
  • low power data transmission
  • System Shutdown current 4uA @3V
  • Integrated 64KB FRAM with 8MBps in-system writes
