The dual 16-bit sigma-delta converters sample voltage and current simultaneously. The CPU16's hardware multiplier computes V × I × cos φ in firmware.
The MSP430FE4272IPMR is listed as Active with no EOL notice or last-time-buy window. Sourcing through independent distribution remains straightforward; the part is quoted to order against an RFQ.
The pinout is documented in the Texas Instruments MSP430FE4272 datasheet. The 64-LQFP package follows the standard MSP430x4xx pin mapping for the FE427x variant.
The core runs at 8 MHz, which is the rated maximum for the MSP430 CPU16 in this device.
