MSP430F6736AIPNR Übersicht
A single-phase metering SoC is a microcontroller with on-chip analog front-end and LCD driver, purpose-built to perform metrology calculations (RMS voltage, RMS current, active/reactive power, energy) for one residential or commercial phase. The MSP430 family belongs to the broader hierarchy: metering MCU -> mixed-signal microcontroller -> 16-bit microcontroller -> ultra-low-power MCU -> embedded processor. Sigma-delta ADCs offer 24-bit resolution at low sample rates, ideal for current transformers and shunt-based sensing where high dynamic range and noise rejection matter more than bandwidth.
Key features include three 24-bit sigma-delta ADCs with differential inputs and programmable gain, hardware AES-256 accelerator on most F67xxA derivatives, integrated LCD driver supporting up to 320 segments, on-chip RTC with calendar, brown-out reset, supply voltage supervisor, and a multi-channel 10-bit SAR ADC on shared pins. Communication interfaces include up to four USCI modules supporting UART/SPI/I2C, IrDA encoder/decoder, and JTAG/SBW for in-system programming and debugging.
The MSP430F6736AIPNR uses TI's MSP430 CPUXV2 16-bit RISC core with a 16-bit register file, hardware multiplier, and four-byte fetch. Code execution from Flash at 25 MHz delivers 1.46 DMIPS/MHz (Whetstone equivalent). The architecture trades absolute throughput for energy efficiency: each peripheral can be individually clock-gated, and the CPU enters one of five low-power modes (LPM0-LPM4) with standby currents below 1 uA.
Typical applications include single-phase electricity meters (Class 0.2/0.5/1.0 accuracy), smart energy monitoring plugs, solar PV string monitors, appliance line-monitoring controllers, and any battery-aware IoT sensor requiring an integrated LCD. Pin compatibility with the F6736A family allows easy migration to higher-memory or lower-cost variants. When designing with this device, place the three sigma-delta ADC inputs in a quiet ground island and route the analog LDO output to dedicated AVDD pins. The device ships in tape and reel (T&R) and is lead-free / RoHS compliant.

Single-Phase Electricity Meter
The MSP430F6736AIPNR is purpose-built for Class 0.2/0.5/1.0 single-phase residential electricity meters per IEC 62053-21. Its three on-chip 24-bit sigma-delta ADCs digitize shunt and current-transformer signals at 4 kHz with 92 dB dynamic range, directly computing RMS voltage, RMS current, and active/reactive energy without an external metrology IC. The 128 KB Flash stores DLMS/COSEM protocol stacks and TOU tariffs; 8 KB RAM handles 4-quadrant metrology tables. Integrated LCD driver (up to 320 segments) eliminates the need for an external driver for kWh displays, and the RTC provides time-of-use billing. The 80-LQFP fits inside a 16x16 mm meter sub-board alongside a power-supply IC and a shunt/CT, achieving a compact BOM. Source: TI MSP430F6736A datasheet, application note SLAA577.

Smart Energy Monitoring Plug
Smart plugs and PDUs benefit from the MSP430F6736AIPNR's three 24-bit sigma-delta ADCs and 25 MHz MSP430 core. The MCU digitizes mains voltage and load current through a shunt resistor, computing real-time power, energy, and power factor at 1-2 second intervals. The 128 KB Flash holds the Wi-Fi or BLE provisioning stack and energy-accumulation firmware; 8 KB RAM is sufficient for one minute of energy smoothing. The four USCI modules run UART for Wi-Fi/BLE modules plus I2C for an EEPROM (M24256-BWMN6TP) and SPI for an AC/DC metering LCD. The 1.8-3.6 V supply aligns with battery-backed design needs, and the 200 uA/MIPS active current keeps standby below 1 uA. Source: TI MSP430F6736A datasheet.

Solar PV String Monitor
Distributed solar PV string monitors sample each panel's current and DC voltage to detect mismatch, bypass diode failure, and shading. The MSP430F6736AIPNR handles up to three isolated string sensors per device, with its 24-bit sigma-delta ADCs offering 100+ dB dynamic range to capture both peak and low-light conditions. With 128 KB Flash, the MCU runs TI's solar PV string-monitoring reference firmware (TI design TIDM-SOLARSTRING) and Modbus RTU over UART for the gateway bus. The 25 MHz CPUXV2 core completes an FFT and MPPT calculation under 5 ms per loop, and the integrated RTC timestamps each telemetry packet. The 80-LQFP package measures 12x12 mm, fitting beneath a weatherproof enclosure. Source: TI MSP430F6736A datasheet, TIDM-SOLARSTRING reference design.

Appliance Line-Monitoring Controller
Washing machines, dishwashers, HVAC indoor units, and EV charge stations embed line-power monitors that need accurate RMS metering with a built-in LCD and RTC for user feedback. The MSP430F6736AIPNR integrates the three ADCs, 320-segment LCD driver, and RTC into a single IC, replacing a metering ASIC plus external RTC plus LCD driver. Its 128 KB Flash stores manufacturer firmware plus IEC 61850 or DNP3 protocol; 8 KB RAM supports touch-button debouncing and HVAC fan-control state machines. Active-mode current of 200 uA/MIPS keeps total system consumption modest, and the 80-LQFP fits on the appliance main control board.

Industrial Power Quality Monitor
Three-channel industrial power-quality monitors measure harmonics, interharmonics, flicker, and transient events on 50/60 Hz mains per IEEE 519 / IEC 61000-4-30. The MSP430F6736AIPNR's three 24-bit sigma-delta ADCs sample three-phase or single-phase-plus-neutral waveforms at 4-8 kHz with sufficient ENOB to compute THD up to the 50th harmonic. Its 25 MHz core runs 1024-point FFTs and event detection loops in real time, and 128 KB Flash stores waveform logs and EN 50160 statistical aggregation. RTC timestamp quality-of-service events; UART ports output IEC 61850 or Modbus TCP frames to the gateway. The 80-LQFP mount fits a DIN-rail sub-board alongside an isolation barrier.

Battery-Aware IoT Sensor Node
Battery-aware IoT nodes (smart thermostats, leak detectors with metering, energy-harvesting wireless sensors) use the MSP430F6736AIPNR for ultra-low-power operation. The CPUXV2 core draws roughly 200 uA/MIPS at 1 MHz and below 1 uA in LPM4 deep-sleep with RTC retention. The three sigma-delta ADCs monitor battery voltage, supply current, and an external sensor (e.g. a moisture or temperature transducer). 128 KB Flash holds the LoRaWAN or Zigbee MAC stack, and 8 KB RAM keeps sleep/wake context. Wake-up is driven by RTC alarm or ADC threshold, making the SoC suitable for 10-year coin-cell or energy-harvested nodes with line-power signal-conditioning front-end.

Designhinweise
Use a separate ferrite bead and decoupling pair for the analog AVDD rail. Recommended: 10 uF bulk + 100 nF + 10 nF ceramic on AVDD, and a TDK MMZ1608 ferrite bead isolating the digital DVDD switching noise from AVDD. The sigma-delta ADCs digitize micro-volt signals, and any supply ripple above 1 mV directly couples into ADC readings. Reference: TI SLAA577 metering application note.
Route the three sigma-delta ADC differential pairs on one layer only, with continuous ground plane below. Keep traces short and matched (within 1 mm), use a guard trace tied to AVSS around each pair, and avoid routing digital signals (LCD, JTAG) across these analog traces. Place the shunt resistor or current-transformer burden within 10 mm of the input pins to limit loop area. The 80-LQFP (PN) package has 0.5 mm pitch; allow 0.25 mm trace clearance.
Estimated: Active-mode current at 25 MHz is about 5 mA (200 uA/MIPS). Verify that your LDO or DC-DC can supply 5 mA without sagging the AVDD rail. The MSP430F6736AIPNR does not have an internal brown-out for the analog section; rely on the integrated supply voltage supervisor (SVS) with threshold set to 2.4 V for 3.3 V operation. The LCD bias charge pump needs at least 1 uF capacitor on the VLCD pin - omitting it causes ghosted segments.
Compliance-Informationen
RoHS compliant and lead-free per TI product page. AEC-Q100 not applicable - this is an industrial / consumer metering MCU; AEC-Q100 automotive variants would be flagged separately on TI's product page.
