Other Parts Discussed in Thread: MSP430FR6047
Tool/software:
Hello All,
We are working water meter application on EVM msp430fr6047.
We wanted the power backup of min 15 years. On referring document Ultrasonic Sensing Subsystem Reference Design for Water Flow Measurement
As per section 3.2.2.5 Average Power Consumption there is below power profile.
with below configuration.
From this we below questions:
1. As per parameters how upstream and downstream pulse time 250 us? Is the represent the time elapsed between firing pulse and capturing it for only upstream?
2. The total current 3.83uA is for 20 pulse or single pulse?
3. Is the power profile listed is based on specific pipe ?
4. As per Table 7 of section 3.2.2.5 A like below
USS INIT (UPS) 413 μs 700 μA (0.289 μA) .
It is written CURRENT CONSUMPTION (INSTANTANEOUS, CONTRIBUTION) what does it exactly represent.
Any help will be greatly appreciated.
