Product details
Overview
MSP430FG6425IPZR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring a 16-bit sigma-delta ADC with 10 external analog inputs, dual 12-bit DACs, integrated LCD driver for up to 160 segments, and four USCI modules (two UART/IrDA/SPI + two I²C/SPI). It operates from 1.8 V to 3.6 V and delivers 250 µA/MHz active current at 8 MHz, targeting battery-powered measurement systems.
For engineers reviewing the MSP430FG6425IPZR datasheet, MSP430FG6425IPZR pinout, MSP430FG6425IPZR application, or MSP430FG6425IPZR equivalent, key selection criteria include its 64 KB flash / 10 KB SRAM configuration, absence of USB PHY (distinguishing it from FG662x), LQFP-100 package compatibility, and support for RTC in LPM3.5 with 0.9 µA shutdown current.
Technical Context
The MSP430FG6425IPZR implements a 16-bit RISC CPU with constant generators and a digitally controlled oscillator (DCO), enabling sub-5 µs wake-up from LPM modes. Its unified clock system integrates FLL, VLO, REFO, XT1 (32 kHz), and XT2 (up to 32 MHz) sources for precise timing control across low-power and high-accuracy applications.
Peripherals include six-channel DMA, hardware multiplier supporting 32-bit operations, four 16-bit timers (TA0 with 5 CC registers; TA1/TA2 with 3 each; TB0 with 7), RTC with calibration logic, and dual op-amps with quad ground switches - all optimized for sensor signal conditioning and metrology-grade analog front-end integration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with constant generators and DCO; enables efficient C code execution and fast low-power mode transitions. |
| Flash / SRAM | 64 KB flash memory + 10 KB SRAM; sufficient for complex metrology firmware with calibration tables and real-time processing buffers. |
| ADC | 16-bit continuous-time sigma-delta ADC with 10 external analog inputs (6 single-ended, 4 selectable SE/differential); supports high-resolution sensor digitization without external signal conditioning. |
| Power Consumption | 250 µA/MHz in active mode (AM); 3.4 µA in standby (LPM3) at 3.0 V; 0.9 µA in RTC-active shutdown (LPM3.5); extends battery life in portable meters. |
| Timers & Peripherals | Four 16-bit timers (TA0/TA1/TA2/TB0), 6-channel DMA, dual 12-bit DACs with synchronization, and four USCI modules (2× USCI_A, 2× USCI_B); enables concurrent communication, waveform generation, and time-critical event handling. |
| LCD Driver | Integrated LCD_B controller supporting up to 160 segments with contrast control; eliminates external display drivers in handheld diagnostic equipment. |
| Operating Voltage | 1.8 V to 3.6 V supply range; compatible with single-cell Li-ion, Li-polymer, or dual-cell alkaline battery systems. |
Pinout & Package
Package: 100-pin LQFP (PZ), 14 mm × 14 mm body size, exposed thermal pad not specified. Pin functions validated per TI SLAS874B Rev. September 2020, Figures 7-1 and 7-2 (MSP430FG6425IPZ).
| Pin/Terminal | Circuit Role | Design Meaning |

| AVCC / AVSS / DVCC / DVSS | Analog and digital power domains | Separate analog/digital supplies reduce coupling noise; AVCC must be decoupled with 1 µF + 100 nF per TI guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-power operation | 0.2 µA shutdown (LPM4.5) and 0.9 µA RTC-active mode (LPM3.5) enable multi-year battery life in maintenance-free field instruments. |

FAQ
What is the maximum system clock frequency supported by the MSP430FG6425IPZR?
The MSP430FG6425IPZR supports a maximum system clock frequency of 20 MHz, achieved using the integrated FLL with high-frequency crystal (XT2) up to 32 MHz or internal DCO. This enables real-time processing of high-sample-rate sensor data while maintaining deterministic timing for communication peripherals and LCD refresh cycles - critical for responsive user interfaces in handheld meters.
Does the MSP430FG6425IPZR include a USB interface?
No, the MSP430FG6425IPZR does not include a USB interface. Unlike the MSP430FG662x series, the FG642x family omits the USB-PHY, USB power system, and USB-PLL. Communication is handled exclusively via four USCI modules (UART, SPI, I²C). This simplifies power design and reduces cost for applications where USB connectivity is unnecessary - such as standalone field instruments with serial or wireless backhaul.
How many analog input channels does the sigma-delta ADC in the MSP430FG6425IPZR support?
The MSP430FG6425IPZR features a 16-bit continuous-time sigma-delta ADC with 10 external analog inputs: 6 dedicated single-ended channels and 4 additional pins configurable as either single-ended or differential pairs. Combined with 4 internal inputs (e.g., temperature sensor, VREF), this provides comprehensive signal acquisition capability for multi-sensor systems without external multiplexers.
What is the purpose of the VREFBG pin (P5.0) on the MSP430FG6425IPZR?
The VREFBG pin (P5.0) on the MSP430FG6425IPZR outputs a stable 1.2 V bandgap reference voltage and also accepts an external reference input (VeREF+). It serves as the precision voltage source for the ADC, DACs, and comparator, ensuring consistent measurement accuracy across temperature and supply variations - essential for calibration-critical applications like clinical diagnostic devices.
Can the MSP430FG6425IPZR operate from a single 1.8 V supply?
Yes, the MSP430FG6425IPZR operates over a supply voltage range of 1.8 V to 3.6 V, fully functional at the minimum 1.8 V rail. At this voltage, it maintains full peripheral operation including the sigma-delta ADC, LCD driver, and real-time clock - enabling direct use with single-cell lithium batteries or energy-harvesting sources where regulated 3.3 V is unavailable.
