Description

This reference design demonstrates an IR reflection sensing solution based on an MSP430™ FRAM microcontroller (MCU) with configurable analog for sensing and measurement applications. It demonstrates the MCU's ultra-low-power feature with the benefit of FRAM technology and integrated transimpedance  amplifier (TIA). A single CR123 battery provides power to the board to make it work more than 10 years.

Features
  • FRAM-based MSP430FR2311 eliminates external EEPROM
  • Integrated transimpediance amplifier (TIA) with pA level low-leakage input
  • Ultra-low average power (MCU 1 μA)
  • 10 year lifecycle with one CR123 battery
  • High-ESD performance with easy layout
