MSP430I2041: MSP430I2041 16-MHz metering AFE with 4 24-bit sigma-delta ADCs, 2 16-bit timers, 32KB Flash, 2KB RAM

Part Number: MSP430I2041

Tool/software:

Dear Team, 

We want use this for metering purpose (for voltage and current), and we are having following queries.

1) Can you give us detailed schematic regarding, or any block diagram, as current block diagram is not enough to understand the functionality of the IC.

2) How many voltages and Current can be measured through this, is there any restriction on usage, likewise half of it for current or voltage?

3) Can we use a pin for voltage at once, then same can be used to measure current (in terms of ADC values)?

4) Is this IC have separate configurations to measure voltage and current?

Looking forward to hearing from you.

Best Regards,

Deep

    Hi Deep,

    You can refer to the reference designs for your questions since they will give you a better idea of what the msp430I family can do. As for voltage and current measurements, it will depend on how the device is being set in the final circuit: the rule is to be within the msp430 datasheet electric characteristics. I'm not sure what you mean by "a pin for voltage at once, then same can be measure current." Finally, the reference designs should give you some insight on how to measure voltage and current since the MSP430 itself uses the sigma-delta channels to capture the data required to do a measurement.

    Let me allow to explain, a pin for voltage at once, then same can be measure current." means,

    Let's say I have configured GPIO4 to measure voltage, and in next version I want to configure same GPIO4 to measure current, kindly confirm.

    Regards,

    Deep

    Hi Deep,
    Since both are analog signals (to measure either voltage or current,) you should be able to configure the pins (or data captured) for any purpose you need in the software.
