Texas Instruments MSP430F6723AIPZ

Overview

MSP430F6723AIPZ from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller designed for single-phase energy metering applications. It integrates two 24-bit sigma-delta ADCs, a 10-bit 200-ksps ADC, LCD driver (up to 320 segments), real-time clock with crystal calibration, and three eUSCI_A modules supporting UART/IrDA/SPI - all in a 100-pin LQFP package operating from 1.8 V to 3.6 V.

For engineers reviewing the MSP430F6723AIPZ datasheet, MSP430F6723AIPZ pinout, MSP430F6723AIPZ application, or MSP430F6723AIPZ equivalent, key selection criteria include its dual SD24_B ADC architecture for current/voltage channel separation, integrated RTC with temperature compensation, low-power LPM3.5 mode (1.24 µA), and support for I²C via eUSCI_B0 - critical for utility meter firmware validation and metrology-grade signal acquisition.

Technical Context

The MSP430F6723AIPZ implements a 16-bit RISC CPU with 25-MHz system clock capability, unified clock system featuring FLL stabilization, VLO/REFO/XT1 sources, and programmable LDO core regulation. Its peripheral set is optimized for metrology: SD24_B converters use differential PGA inputs with internal reference, while ADC10_A provides six external + two internal channels including on-die temperature sensing.

Power management includes four low-power modes (LPM0–LPM4.5), with sub-µA shutdown (LPM4.5 = 0.78 µA) and 3-µs wake-up from LPM3. The auxiliary supply subsystem isolates RTC, XT1, and backup memory (4 × 16 bits), enabling accurate timekeeping during main power loss without external circuitry.

FAQ

What is the maximum system clock frequency supported by the MSP430F6723AIPZ?

The MSP430F6723AIPZ supports a maximum system clock frequency of 25 MHz, enabled by its integrated FLL control loop and DCO oscillator. This speed allows real-time execution of metrology algorithms such as RMS calculation, harmonic analysis, and DLMS protocol handling while maintaining ultra-low power consumption in active mode (265 µA/MHz at 8 MHz, 3.0 V).

How many analog input channels does the MSP430F6723AIPZ support for energy measurement?

The MSP430F6723AIPZ supports six external analog input channels via its 10-bit ADC10_A module, plus two internal channels (including a temperature sensor), and two independent 24-bit SD24_B sigma-delta ADCs with differential PGA inputs - enabling full single-phase metering with separate voltage and current sensing paths.

Does the MSP430F6723AIPZ include hardware support for LCD display driving?

Yes, the MSP430F6723AIPZ includes an integrated LCD_C peripheral supporting up to 320 segments in 8-mux mode. It provides programmable contrast control, static and multiplexed drive capability, and direct memory-mapped segment control - eliminating the need for external LCD controllers in utility meter displays.

What low-power modes are available on the MSP430F6723AIPZ, and what is the lowest current draw?

The MSP430F6723AIPZ offers five low-power modes (LPM0–LPM4.5). The lowest current draw is in LPM4.5 (shutdown mode) at 0.78 µA at 3.0 V, with full RAM retention and supply supervisor active. LPM3.5 (RTC active with crystal) draws 1.24 µA at 3.0 V - ideal for timekeeping during main power loss.

Is the MSP430F6723AIPZ pin-compatible with other devices in the MSP430F672x family?

Yes, the MSP430F6723AIPZ is pin-compatible with all 100-pin LQFP (PZ) variants in the MSP430F672x family, including MSP430F6721AIPZ through MSP430F6726AIPZ. Pin functions, power domains, and peripheral mappings are identical - enabling firmware reuse and hardware scalability across memory and feature tiers.
