Product details
Overview
MSP430F47173IPZ from Texas Instruments is an ultralow-power mixed-signal microcontroller designed for precision electricity metering applications. It integrates three 16-bit sigma-delta ADCs with differential PGA inputs, 92KB Flash, 8KB RAM, and an integrated LCD driver supporting up to 160 segments - enabling direct connection to polyphase meter displays without external drivers.
For engineers reviewing the MSP430F47173IPZ datasheet, MSP430F47173IPZ pinout, MSP430F47173IPZ application, or MSP430F47173IPZ equivalent, key selection considerations include its 100-pin QFP package, three-channel SD16_A ADC architecture, real-time clock capability via Basic Timer, and support for I²C, SPI, and UART through four USCI modules - all operating within 1.8 V–3.6 V supply range.
Technical Context
The MSP430F47173IPZ implements a 16-bit RISC CPU with 62.5-ns instruction cycle time and five software-selectable low-power modes, including LPM4 with 0.2 µA off-mode current and sub-6 µs wake-up latency. Its FLL+ system enables stable clock generation from internal DCO or external crystals (XT1/XT2), supporting precise timing for metrology-grade sampling.
Three independent sigma-delta ADC channels (SD16_A) each accept differential analog inputs with programmable gain, directly interfacing with current/voltage sensor outputs in single-phase and polyphase energy meters. The on-chip DMA controller supports autonomous data transfer from ADC results to RAM, reducing CPU load during high-resolution conversion sequences.
