Description

By applying low power modes and FRAM technology this reference design utilizes 1-wire device communication to emulate EEPROM functionality on an MSP430™ microcontroller (MCU).  This solution includes the ability to be powered parasitically from the communication line and allocates more memory space than is available than current 1-wire devices on the market.

Features
  • Complete 1-Wire protocol support assures an easy transition and effortless substitution for similar EEPROM devices
  • Uses LPMs to accomplish an average standby current consumption of 600 nA in standby mode
  • Design is achievable on any MSP430 FRAM MCU and allows for flexibility in the available EEPROM memory space
  • Includes selectable operation modes such as dedicated or parasitic power
  • Provided firmware may be nodified for use in other 1-wire applications
