The seven 16-bit sigma-delta ADCs are the part's headline differentiator. In a three-phase energy meter, each phase voltage and current pair consumes two ADC channels, leaving one spare for neutral current or tamper detection.
Yes, the MSP430F47187IPZR is end-of-life (EOL). Remaining inventory is available through independent distribution; no official replacement part number is listed. For new designs, evaluate TI's active MSP430FRxx or MSP430F67xx series.
The supply voltage range is 1.8 V to 3.6 V, compatible with standard 3.3 V logic and single-cell battery applications.
No, the I/O pins are not 5 V tolerant at the supply range of 1.8 V to 3.6 V. Level shifting is required for 5 V interfaces.
No official replacement part number is documented. A functional equivalent within the MSP430F47x family should be verified for ADC count, memory, and package compatibility.
