MSP430F6723IPZ - 25 MHz Metering MCU | Texas Instruments
MPN: MSP430F6723IPZ ✓ AktifMSP430F6723IPZ Ringkasan
A mixed-signal microcontroller combines a digital processor with analog front-end and energy-measurement peripherals on one device. The MSP430F6xx family belongs to the broader embedded MCU category and provides programmable real-time control for energy meters, utility data concentrators, industrial monitoring systems, and portable measurement equipment. Its integration reduces component count while keeping sensing, computation, display control, and communication functions within one low-power device.
Key features include 72 configurable I/O pins, two 16-bit sigma-delta ADCs, LCD drive capability, and an internal real-time clock. The device operates from a 3.6 V low-supply range and is specified at 265 µA/MHz in active mode with all system clocks operating at 8 MHz and 3.0 V. These characteristics support metering designs that must continuously acquire analog energy signals while controlling a segment or matrix LCD.
The MSP430 architecture uses a 16-bit RISC core with 16-bit registers and constant generators, supporting efficient metering algorithms and compact firmware. Multiple low-power operating modes help reduce energy consumption when the meter is idle, while the real-time clock allows time-of-use measurement and load-profile timing without an external clock component.
Typical applications include single-phase electricity meters, smart grid endpoint equipment, industrial energy monitors, and low-cost data loggers with LCD displays. The two sigma-delta channels are particularly relevant to current and voltage sensing, where oversampled conversion and digital filtering improve signal resolution before calculations are performed by the CPU.
When laying out a meter board, reserve isolated analog routing for the sigma-delta inputs and keep LCD segment, crystal, and high-current drive connections away from the measurement front end. Confirm the complete pin-assignment table in the manufacturer datasheet before routing, especially for the exposed ground and supply pins in the 100-pin LQFP footprint.
This page organizes the device specifications, verified alternatives, metering application guidance, and PCB-level design considerations to support faster component selection and board bring-up.

Aplikasi Biasa
MSP430F6723IPZ patut untuk 6 aplikasis: Single-Phase Smart Electricity Meter, Smart Grid Endpoint and Data Concentrator, Industrial Energy Monitoring Terminal, LCD-Equipped Utility Data Concentrator, Battery-Powered Environmental Sensor, Precision Analog Measurement Controller.
Single-Phase Smart Electricity Meter
The MSP430F6723IPZ fits single-phase metering designs because its two sigma-delta ADCs can acquire current- and voltage-related analog signals while the 25 MHz 16-bit CPU executes measurement and calibration routines. The 64 KB Flash holds firmware and calibration tables, while 4 KB RAM supports short-term measurement buffers. Its integrated LCD capability and real-time clock simplify display and time-of-use scheduling. Designers should still implement the precision current-shunt, voltage-divider, and analog-isolation network according to the meter architecture.

Smart Grid Endpoint and Data Concentrator
The MSP430F6723IPZ supports smart-grid endpoint controllers that gather energy measurements, maintain time-of-use schedules, and present status on a local LCD. Its low-power architecture and 265 µA/MHz active-mode figure at 8 MHz and 3.0 V help control consumption between communication transactions. The 100-pin LQFP provides dedicated access to metering peripherals, while the 16-bit CPU can run protocol tasks alongside measurement processing. Confirm interrupt latency and communication-driver resource demands against the 4 KB RAM limit.

Industrial Energy Monitoring Terminal
For industrial energy-monitoring equipment, the MSP430F6723IPZ combines programmable ADC acquisition, LCD control, and an integrated real-time clock in one 100-pin device. Engineers can use the two sigma-delta channels for voltage-derived and current-derived measurements, then perform scaling and filtering in firmware. The -40 °C to 85 °C temperature range supports typical industrial environments when the board also meets its own thermal and isolation requirements. The 64 KB Flash is suitable for calibration and logging firmware but may constrain large data buffers.

LCD-Equipped Utility Data Concentrator
The MSP430F6723IPZ is appropriate for compact utility concentrators that need a local operator display without a separate display controller. Its LCD interface reduces system complexity, while the real-time clock supports interval-based collection and synchronization routines. The two sigma-delta ADCs can monitor auxiliary analog quantities in addition to the primary energy path. Board layout should separate LCD drive and supply routing from sensitive analog inputs to reduce coupling, and firmware should use low-power modes during long idle intervals.

Battery-Powered Environmental Sensor
The MSP430F6723IPZ can serve as the control and measurement hub in a low-duty-cycle environmental sensor using two low-rate analog channels for inputs such as temperature or pressure. Its 265 µA/MHz active-mode specification at 8 MHz and 3.0 V provides a starting point for power budgeting, while multiple low-power modes reduce consumption during sensor settling and data-transmission intervals. The real-time clock provides scheduled sampling without a separate timing IC. Use the lower-power modes and clock tree in the manufacturer datasheet for the final battery-life calculation.
Disebarkan
Precision Analog Measurement Controller
The MSP430F6723IPZ also suits custom measurement instruments in which a pair of sigma-delta channels feeds a 16-bit processing pipeline. Oversampling and digital filtering can be implemented in firmware, allowing the 25 MHz CPU to handle scaling, compensation, and control functions without a separate DSP. The integrated LCD interface supports local readouts, and the real-time clock can timestamp samples. Analog layout remains decisive: use short, symmetrical routes, solid ground returns, and the decoupling arrangement specified in the manufacturer datasheet.

Catatan Desain
Route the two sigma-delta input channels as short, symmetric analog traces with a continuous ground reference beneath them. Keep the LCD drive connections, switching-supply traces, and high-current relay or LED drivers away from the measurement inputs. Place analog bypass capacitors close to their designated supply pins, and use the manufacturer pin table when allocating the numerous power and ground pins of the 100-LQFP package.
Estimated: the manufacturer lists 265 µA/MHz at 8 MHz and 3.0 V, implying approximately 2.12 mA for the CPU in that stated active-mode condition. This is not the complete meter-system consumption because ADC activity, LCD drive, I/O loading, and low-power mode residence time add to the budget. Measure the assembled meter across sleep, acquisition, display, and communication phases before sizing the energy-storage element.
Do not treat a family cross-reference as proof of firmware-level equivalence. Before substituting an MSP430F67xx candidate, compare the 100-pin PZ footprint, ADC input assignments, LCD mapping, real-time-clock connections, reset and debug pins, supply requirements, and interrupt vector resources. Changing the device can require firmware updates even when the land pattern remains the same.
