MSP430F6734AIPZR — the metrology-grade 16-bit MCU
It targets energy measurement, smart metering, and precision sensor applications where the three 24-bit sigma-delta ADCs (A/D 8x10b, 3x24b) handle the analog front-end directly.
What the 24-bit ADC array means for the BOM
Three 24-bit sigma-delta ADCs are the headline feature. They allow simultaneous voltage and current sensing on multiple phases — a single MSP430F6734AIPZR can handle a three-phase energy meter with neutral current measurement, eliminating a separate metrology AFE. The additional 8x10-bit ADC handles auxiliary channels (temperature, tamper detection, or calibration trim). This integration collapses the analog front-end BOM for polyphase metering and precision instrumentation.
Peripheral set and connectivity for system integration
The part integrates I²C, IrDA, LINbus, SCI, SPI, and UART/USART connectivity, plus a built-in LCD driver — useful for direct segment-display drive in meter and panel applications. The 72 I/O lines and peripherals including Brown-out Detect/Reset, DMA, POR, PWM, and WDT cover the control and communication needs of a typical smart-meter or sensor-hub design without external glue logic.
