TIDM-FRAM-IRREFLECTIONSENSING
MSP430FR2311 Microcontroller IR Reflection Sensing Reference Design
TIDM-FRAM-IRREFLECTIONSENSING
Overview
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
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
