Description

  • TIDM-OPTICALWATERMTR, Water Meter Reference Design for Optical Sensors, Using Extended Scan Interface (ESI). One of the challenges in battery operated water meters is to continuously measure the water flow information while consuming as little energy as possible. The EVM430-FR6989 used in this design features a MSP430 FRAM-based microcontroller with 100uA/MHz active-mode current, 450nA standby-mode current with the real-time clock enabled and integrated low-power analog and digital peripherals. Additionally, the MCU offers for near infinite write endurance, quick/low-power writes and data flexibility
