MSP430F6736AIPN Présentation
A metering SoC (System-on-Chip) is a microcontroller that integrates application-specific analog front-end peripherals - in this case, three precision Sigma-Delta analog-to-digital converters - directly onto the same silicon as the CPU, memory, and display drivers. This topology eliminates the need for an external ADC chip in single-phase energy-meter products, reducing BOM cost and PCB area. The MSP430F6736AIPN sits inside TI's MSP430F6xx metering family, which extends from the broader MSP430 ultra-low-power MCU lineage into the power-measurement domain. Synonyms commonly used in the trade include 'metering MCU', 'energy-meter SoC', and 'e-meter microcontroller'.
Key differentiating features of the MSP430F6736AIPN include its 128KB of in-system programmable Flash (sufficient for storing calibration tables, metrology algorithms, and display fonts), an integrated segmented-LCD driver that eliminates external LCD bias-generation hardware, the three 24-bit Sigma-Delta ADCs which simultaneously sample voltage and current channels for class-0.2 or class-0.5 energy accuracy, and ultra-low-power modes that allow the entire meter to draw under 4 mA active while continuously metering.
Technically, the device combines a 16-bit RISC MSP430 CPUXV2 core with hardware multiplier, an embedded RTC with calendar, brown-out reset, supply-voltage supervisor, watchdog timer, and multiple timer/capture modules. The three SD24 ADCs achieve effective resolution suitable for IEC 62053-22 class-0.2 meters, and the integrated LCD driver supports up to 320 segments in 8-mux mode. The 80-pin LQFP package exposes all analog and digital pins, with the PN suffix identifying a 12x12 mm body.
Typical applications include single-phase residential electricity meters, smart-plug energy monitors, in-home display panels, sub-metering for solar inverters, and industrial power-monitoring controllers. The combination of three SD ADCs and an LCD driver makes the part a true single-chip solution for IEC-compliant class meters.
When designing with this device, place the crystal and the SD24 RC components as close to the respective pins as the layout allows, route the analog and digital grounds as separate nets joined at a single point near the IC, and follow TI's 'Single-Phase Metering with the MSP430F6736A' reference design for ADC gain calibration.

Applications typiques
MSP430F6736AIPN convient pour 6 applications: Single-Phase Residential Electricity Meter, Smart Plug Energy Monitor, Solar Inverter Sub-Meter, Industrial Power Monitoring Controller, In-Home Display Panel, EV Charging Station Energy Meter.
Single-Phase Residential Electricity Meter
The MSP430F6736AIPN is the canonical single-chip solution for IEC 62053-21 class-1 or class-2 residential meters. Its three 24-bit SD24 ADCs simultaneously sample the voltage channel and the two current channels (CT or shunt), producing true-RMS active, reactive, and apparent energy with built-in phase-error correction. The 128KB Flash holds the metrology library plus the DLMS/COSEM or IEC 62056-21 communication stack for AMI, while the integrated LCD driver drives the segmented display without external bias hardware. Compared with a discrete ADC + general MCU approach, this SoC reduces BOM by ~$1.50 and shrinks PCB area by roughly 30%.
Recommandé
Smart Plug Energy Monitor
Wi-Fi or BLE smart plugs that report per-outlet energy use benefit from the MSP430F6736AIPN's three SD24 ADCs and ultra-low-power modes. The two current ADCs support either a single CT plus voltage channel or dual CTs for power-strip monitoring of multiple outlets. Active current under 4 mA keeps idle consumption low so the plug meets Energy Star standby requirements. The integrated RTC enables accurate time-of-use (TOU) tariff schedules, and the 128KB Flash comfortably holds TLS client stacks for cloud-paired smart-plug designs.
Recommandé
Solar Inverter Sub-Meter
Sub-metering in single-phase solar inverters needs accurate bidirectional energy measurement, which the three 24-bit SD24 ADCs of the MSP430F6736AIPN handle natively. Channel 0 measures grid-side voltage; channels 1 and 2 measure grid current and PV current respectively, allowing net-energy calculation across a daily cycle. The wide -40C to +85C operating range suits outdoor inverter enclosures, and the LCD driver can drive a 4-digit in-home display showing instantaneous power and cumulative kWh. Compared with class-0.5 industrial ADCs, this SoC achieves IEC class-0.2 accuracy at lower cost.
Recommandé
Industrial Power Monitoring Controller
Inside industrial PDUs and machine-power monitors, the MSP430F6736AIPN serves as the metering brain. Its 25 MHz MSP430 CPUXV2 core runs the metrology task plus Modbus RTU over UART, while the three SD24 ADCs simultaneously sample three-phase or multi-channel loads (single SoC handles up to three loads in single-phase systems). The wide 2.5V/3.3V supply range simplifies integration with industrial 24V-derived rails, and the integrated RTC timestamps energy logs without an external RTC chip. The 8KB RAM is sufficient for a circular event log up to several thousand entries.
Recommandé
In-Home Display Panel
Companion in-home displays (IHDs) for AMI smart meters pair with the MSP430F6736AIPN to show real-time kWh, cost, and CO2 footprint. The SoC's integrated LCD driver (up to 320 segments) directly drives the segmented glass without a charge-pump IC, and its ultra-low LPM3 sleep current (~1 uA with RTC) means the display can run for years on two AA batteries. The three SD24 ADCs are repurposed for an optional local-measurement mode (e.g., plug-through reference display). Compared with an LCD-driver-less MCU plus external HT1621, this SoC saves roughly $0.80 BOM.
Recommandé
EV Charging Station Energy Meter
AC Level-2 EVSEs require accurate, tamper-resistant single-phase metering, which the MSP430F6736AIPN provides with three SD24 ADCs and 128KB Flash for the OCPP 1.6/2.0.1 communication stack. The integrated RTC supports time-of-use billing aligned with utility schedules, and the wide -40C to +85C range handles outdoor cabinet thermal stress. Compared with class-0.2 industrial metering ICs (e.g., ADE7953), the MSP430F6736AIPN delivers equivalent accuracy with a 32-bit math advantage for harmonic analysis, plus full LCD support for the EVSE's user interface.

Notes de conception
Route AVCC/AVSS and VCC/VSS as separate nets joined at a single point near the IC's analog ground pin (pin 18). Place the SD24 RC antialiasing filters within 5 mm of each A0+/A0-, A1+/A1-, A2+/A2- pin pair to attenuate switching-noise injection from the digital supply. The Xin/Xout 32.768 kHz crystal traces should be short and guarded by a ground ring to keep RTC tick accuracy within +/- 20 ppm.
Use a 10 uF bulk + 100 nF ceramic decoupling on VCC (pin 27) and a separate 10 uF + 100 nF on AVCC (pin 17). The integrated LDO that derives the core rail from VCC requires at least 4.7 uF of low-ESR bulk on its output. Power-rail sequencing is not required - the part tolerates simultaneous ramp - but the RTC crystal must be present before exiting LPM4.5 retention.
Do not exceed the absolute maximum VCC of 3.6 V; reverse polarity on AVCC versus VCC can permanently destroy the internal LDO. The SD24 ADCs require a calibration cycle after each power-up; refer to the 'Single-Phase Metering with MSP430F6736' TI application note (SLAE034) for the recommended sequence. Finally, unused GPIO should be configured as outputs (not inputs left floating) to avoid parasitic current draw in LPM modes.
Keep the SD24 ADC traces differential and matched in length. Place the differential pair over a continuous ground plane and avoid crossing noisy digital traces. For class-0.2 meters, the ADC clock should be derived from the DCO locked to the 32 kHz crystal (REFO mode) rather than the DCO directly, to keep gain error below 0.1% across the industrial temperature range.
