16-bit MCU with dual ADC for metering and sensor fusion
The Texas Instruments MSP430F6731AIPZR is a 16-bit MCU clocked at 25 MHz. It carries 32 KB of Flash program memory and 2K x 8 of RAM, with 72 general-purpose I/O lines.
Lifecycle and sourcing posture
The manufacturer lists this part as Active, though some channel data flags an EOL-hot signal. That discrepancy means a buyer should not assume indefinite factory supply. For a BOM line that requires long-term stability, qualifying a second source or a pin-compatible MSP430F6xx variant now is prudent. We source and quote this part to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time. No official successor order code appears in the record, so any replacement would require a design review of the dual-ADC and peripheral set.
Industrial temperature and package
Rated for -40 to 85 °C ambient, the MSP430F6731AIPZR fits outdoor enclosures and factory-floor controllers.
