MSP430F6736AIPZ - 25MHz MCU, 128KB Flash, 3 SD ADC | TI
MPN： MSP430F6736AIPZ ✓ 啟用中MSP430F6736AIPZ 概覽
An MSP430 microcontroller is a 16-bit RISC mixed-signal processor from Texas Instruments designed for ultra-low-power embedded applications. The MSP430 family integrates an orthogonal RISC architecture with configurable on-chip peripherals including ADCs, timers, communication interfaces, and LCD drivers. MSP430 devices dominate battery-powered metering, sensor nodes, and portable instrumentation due to sub-microamp standby currents and integrated analog front-ends that would otherwise require external components.
Key features of the MSP430F6736AIPZ include hardware multiplier, 32-bit hardware multiplier, DMA controller, multiple low-power modes down to RAM retention, three 24-bit sigma-delta ADCs with programmable gain, integrated LCD driver supporting up to 320 segments, and a real-time clock module. The 100-pin LQFP package exposes extensive GPIO and multiple serial interfaces (UART, SPI, I2C) alongside the metering-specific peripherals, eliminating external ADC chips in single-phase meter designs.
The MSP430F6736AIPZ uses a von Neumann 16-bit architecture with a 16-register file, allowing any register to act as an accumulator or address pointer. Three independent sigma-delta ADCs sample voltage and current waveforms simultaneously at programmable data rates, with built-in reference and PGA eliminating most external analog conditioning. The 128KB Flash supports in-field firmware updates, and 8KB RAM is sufficient for metering algorithm storage plus display buffers.
Typical applications include single-phase electricity meters, smart plug energy monitors, power-quality analyzers, and utility AMI endpoints. The integrated LCD driver simplifies display integration for meter front panels. Industrial sensor transmitters and battery-powered data loggers also benefit from the ultra-low-power sleep modes and RTC wake functionality.
Designers should plan PCB layout with separate analog and digital ground planes, keeping the sigma-delta ADC traces short and isolated from switching nodes. Use low-ESR ceramic bypass capacitors within 5mm of each supply pin. The integrated peripherals reduce BOM cost versus discrete ADC-plus-MCU architectures, but firmware should still use the hardware CRC and watchdog for IEC 62053-22 compliance.

典型應用
MSP430F6736AIPZ 適用於 6 應用s: Single-Phase Electricity Meter, Smart Plug Energy Monitor, Power Quality Analyzer, Industrial Sensor Transmitter (4-20 mA), Battery-Powered Data Logger, Utility AMI Communication Module.
Single-Phase Electricity Meter
The MSP430F6736AIPZ is purpose-built for IEC 62053-21/22 class-0.5 single-phase electricity meters. The three integrated 24-bit sigma-delta ADCs simultaneously sample voltage and two current channels (live and neutral) at rates up to 4 kHz, enabling real-time active/reactive power and RMS calculation in firmware without external ADCs. The 128 KB Flash supports the metering algorithm plus DLMS/COSEM or IEC 62056-21 communication stacks, while 8 KB RAM holds waveform buffers and tariff schedules. The integrated LCD driver drives up to 320 segments for consumption, voltage, and tariff displays on the meter front panel. The 1.8V-3.6V supply range allows direct connection to 2 x AA or 3.3 V regulated metrology supplies. According to TI reference design TIDM-AUX-MODULE, the device achieves better than 0.5 percent accuracy across the industrial temperature range.
推薦
Smart Plug Energy Monitor
Consumer smart plugs that report per-outlet energy consumption use the MSP430F6736AIPZ as the metering engine and the connectivity host MCU. The three SD ADCs measure mains voltage and current through a shunt or CT, while the integrated RTC timestamps consumption records for hourly/daily profile generation. UART/SPI interfaces connect to a Wi-Fi or sub-GHz radio module for cloud data upload. The ultra-low-power LPM3/LPM4 sleep modes (sub-microamp RAM retention) allow battery-backed designs that retain consumption logs across power outages. According to TI, the DMA controller offloads ADC sample transfer from the CPU, leaving processing headroom for power-quality event detection (sag, swell, transient) at the same time as continuous metering.
推薦
Power Quality Analyzer
Portable power-quality analyzers use the MSP430F6736AIPZ to capture voltage and current waveforms for harmonic analysis up to the 63rd harmonic per IEC 61000-4-30. The three 24-bit sigma-delta ADCs deliver better than 90 dB dynamic range needed for THD measurement at 1 percent accuracy. The 128 KB Flash accommodates FFT libraries plus user interface code, and 8 KB RAM holds N-sample windowed waveform buffers. The integrated LCD driver displays real-time voltage, current, power factor, and harmonic spectrum on a 320-segment display without an external controller. According to TI, the hardware multiplier accelerates Goertzel and FFT calculations, allowing real-time harmonic analysis at 50/60 Hz line frequencies without CPU saturation.
推薦
Industrial Sensor Transmitter (4-20 mA)
Loop-powered 4-20 mA sensor transmitters for pressure, flow, or temperature use the MSP430F6736AIPZ to digitize low-level sensor signals and modulate loop current. The three SD ADCs read primary, secondary, and reference channels for ratiometric measurement that cancels supply drift over the 3.6-12 mA loop current range. The 1.8V-3.6V supply range allows direct operation from a low-drop linear regulator fed by the 4-20 mA loop. According to TI, the LPM3 sleep mode with RTC wake keeps quiescent current under 100 uA, enabling HART protocol overlay or wirelessHART via an external radio module while maintaining the 3.6 mA minimum loop budget.
推薦
Battery-Powered Data Logger
Multi-channel battery-powered data loggers for environmental monitoring, cold-chain tracking, or industrial asset health benefit from the MSP430F6736AIPZ ultra-low-power architecture. The three SD ADCs read thermocouples, RTDs, or load cells with built-in PGA gain up to 16x, eliminating external instrumentation amplifiers. RTC wake on programmable intervals triggers ADC sampling, DMA stores results to RAM, and the CPU returns to LPM4 sleep - drawing less than 1 uA between events. According to TI, with 8 KB RAM and 128 KB Flash, the device can store months of timestamped measurements while running the display update, file system, and BLE pairing. Typical 2 x AA battery life exceeds 5 years at 1 sample/minute.
推薦
Utility AMI Communication Module
Advanced Metering Infrastructure (AMI) communication modules for utility AMI endpoints use the MSP430F6736AIPZ as the metering host paired with RF or PLC transceivers. The device reads pre-digitized consumption from the metrology ADC or uses one SD ADC for residual-channel measurements. UART/SPI interfaces connect to the radio (sub-GHz, LoRa, or NB-IoT) for remote data upload. The LCD driver supports customer information displays on the meter face. According to TI reference design TIDM-AUX-MODULE, the integrated RTC enables time-of-use tariff scheduling without external RTC chips, and the hardware AES accelerator in some family variants supports secure AMI data encryption.

主要差異化特點
- Highest Flash tier in F6736A metering family (對比MSP430F6735AIPZ)
- 100-LQFP package exposes full metering peripheral set (對比MSP430F6736AIPN)
- Updated silicon revision improves SD ADC linearity (對比MSP430F6736IPZ)
設計說明
Use separate analog (AVCC/AVSS) and digital (DVCC/DVSS) ground planes joined at a single point beneath the IC. Place the 32.768 kHz crystal within 5 mm of the XIN/XOUT pins with short traces and a ground guard ring to minimize clock jitter that translates into metering timing error. Bypass each AVCC and DVCC pair with 100 nF ceramic plus 4.7 uF bulk within 5 mm of the pins.
Route the three sigma-delta ADC differential pairs (SD0P/N, SD1P/N, SD2P/N) as impedance-matched differential traces with constant spacing and length matching within 0.5 mm. Surround the pairs with ground pour on both sides. Avoid routing digital lines parallel to or crossing the SD ADC traces. Use the internal 1.2V reference where possible to minimize external noise injection.
Estimated: at 25 MHz active mode with all 3 SD ADCs sampling at 4 kHz, the device draws approximately 18-22 mA from a 3.3 V supply, dissipating 60-73 mW. In LPM3 sleep with RTC running, current drops to approximately 2.1 uA. Use a low-Iq LDO (such as TPS78230) to maximize battery life in battery-backed meter designs.
Do not leave unused SD ADC inputs floating - tie them to AVSS through 100 ohm resistors to prevent noise pickup that contaminates the active channel. Ensure the JTAG TEST pin (PJ.3) is left open or pulled to DVSS in production designs; floating state may invoke JTAG test mode on power-up. Disable unused peripherals in the PMM module to minimize active current.
