Product details
Overview
MSP430F47186IPZ from Texas Instruments is an ultralow-power mixed-signal microcontroller designed for poly-phase electricity metering, featuring 116KB Flash, 8KB RAM, six 16-bit sigma-delta ADCs with differential PGA inputs, integrated LCD driver for up to 160 segments, and four USCI modules supporting UART, IrDA, SPI, and I²C.
For engineers reviewing the MSP430F47186IPZ datasheet, MSP430F47186IPZ pinout, MSP430F47186IPZ application, or MSP430F47186IPZ equivalent, key selection considerations include sigma-delta ADC channel count, LCD segment drive capability, real-time clock integration, supply voltage range (1.8–3.6 V), and QFP-100 package compatibility with metering reference designs.
Technical Context
The MSP430F47186IPZ implements a 16-bit RISC CPU with 62.5-ns instruction cycle time and three-channel DMA, enabling high-precision synchronous sampling across all six sigma-delta ADCs. Its FLL+ oscillator supports fast wake-up (<6 µs) from LPM4, critical for event-triggered metering firmware execution.
It integrates dual 16-bit timers (Timer_A3 and Timer_B3), hardware multiplier, brownout detector, and programmable SVS with level detection-enabling autonomous energy measurement, tamper detection, and secure firmware updates without external supervision.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Flash Memory | 116KB - sufficient for full metrology firmware, communication stacks (DLMS/IEC 62056), and calibration data storage |
| RAM | 8KB - supports concurrent ADC buffering, LCD refresh, and real-time tariff calculation |
| Sigma-Delta ADCs | 6 × 16-bit - enables simultaneous voltage/current measurement across three-phase + neutral configurations |
| LCD Driver | 160 segments - drives full-feature utility meter displays including icons, digits, and status indicators |
| Supply Voltage | 1.8 V to 3.6 V - compatible with single-cell Li-ion or regulated 3.3V meter power rails |
| Active Current | 350 µA at 1 MHz, 2.2 V - ensures >10-year battery life in standby-mode metering applications |
| Package | 100-pin QFP (PZ) - provides dedicated analog input pairs (A0.0± to A5.0±), AVSS/AVCC isolation, and LCD COM/SEG routing |
Pinout & Package
Package: 100-pin plastic quad flatpack (QFP), PZ package, surface-mount, 0.5 mm pitch, 14 mm × 14 mm body size.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

The MSP430F47186IPZ supports six independent 16-bit sigma-delta ADCs, each with differential PGA inputs (A0.0± through A5.0±), enabling true simultaneous sampling across all channels. This configuration is validated for three-phase + neutral metering topologies and is explicitly documented in the SLAS626C datasheet for the MSP430F471x6 family variant.
Does the MSP430F47186IPZ include an integrated real-time clock (RTC)?
Yes, the MSP430F47186IPZ includes a hardware real-time clock implemented within its Basic Timer module, supporting calendar mode, alarm interrupts, and battery-backed operation. It uses the ACLK source and is fully functional without external components, enabling time-of-use billing and demand logging in standalone meter applications.
What is the operating temperature range for the MSP430F47186IPZ?
The MSP430F47186IPZ is rated for operation from –40°C to +85°C, as confirmed by the "AVAILABLE OPTIONS" table in SLAS626C. This industrial temperature grade ensures reliable performance in outdoor meter enclosures and unconditioned electrical cabinets across global utility deployments.
Can the MSP430F47186IPZ drive a 160-segment LCD without external bias circuitry?
Yes, the MSP430F47186IPZ integrates a programmable LCD_A controller capable of driving up to 160 segments with internal charge pump and contrast control. The LCDCAP/R33 pin connects to an external capacitor to generate internal bias voltages, eliminating the need for external LCD bias generators in compliant designs.
How many USCI modules does the MSP430F47186IPZ provide, and what protocols do they support?
The MSP430F47186IPZ provides four Universal Serial Communication Interface (USCI) modules: USCI_A0, USCI_A1, USCI_B0, and USCI_B1. USCI_Ax supports UART (with auto-baudrate), IrDA, and SPI; USCI_Bx supports I²C and SPI. This enables concurrent communication on optical, M-Bus, and RF interfaces without external bridge ICs.
