Overview
MSP430FG6625IZQWR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring a 16-bit sigma-delta ADC, dual 12-bit DACs, integrated full-speed USB, LCD driver for up to 160 segments, and 64KB flash/8KB+2KB SRAM. It operates from 1.8 V to 3.6 V and targets battery-powered precision measurement systems such as handheld medical diagnostic meters.
For engineers reviewing the MSP430FG6625IZQWR datasheet, MSP430FG6625IZQWR pinout, MSP430FG6625IZQWR application, or MSP430FG6625IZQWR equivalent, this page delivers verified technical context, package-specific pin functions, low-power mode current values, USB timing parameters, and validated alternative options for metrology-grade embedded designs.
Technical Context
The MSP430FG6625IZQWR implements a 16-bit RISC CPU with constant generators and a digitally controlled oscillator (DCO), enabling sub-5 µs wake-up from LPM3. Its unified clock system integrates FLL, VLO, REFO, XT1 (32 kHz), and XT2 (up to 32 MHz) sources with programmable LDO core regulation (1.5 V / 2.0 V / 2.5 V).
It integrates a continuous-time sigma-delta ADC with 10 external analog inputs (6 single-ended + 4 configurable SE/differential), dual op-amps, quad ground switches, voltage comparator, four USCIs (two UART/IrDA/SPI + two I²C/SPI), RTC with crystal-backed LPM3.5 operation, and hardware multiplier supporting 32-bit operations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FG6626IZQW | 128 KB flash, identical peripherals and pinout; same ZQW package and USB/LCD/ADC capabilities. | Required when firmware size exceeds 64 KB or future-proofing for feature expansion is needed. | Select MSP430FG6626IZQW if design requires >64 KB code space while retaining identical hardware layout and USB functionality. |
| MSP430FG6425IZQW | No USB module; 10 KB SRAM (vs. 8 KB + 2 KB USB SRAM); otherwise matches ADC, DAC, op-amp, and LCD features. | Suitable for cost-sensitive, non-USB applications where local display and analog processing suffice. | Choose MSP430FG6425IZQW only when USB connectivity is unnecessary and lower BOM cost justifies loss of full-speed interface. |
Compared with MSP430FG6625IZQW, MSP430FG6626IZQW offers double flash capacity without layout changes, while MSP430FG6425IZQW removes USB to reduce cost - making the former ideal for scalable firmware and the latter for USB-free metrology endpoints.

How many analog inputs does the sigma-delta ADC on the MSP430FG6625IZQWR support?
The MSP430FG6625IZQWR's continuous-time sigma-delta ADC supports 10 external analog inputs: 6 single-ended and 4 configurable as either single-ended or differential. Additionally, it accepts 5 internal inputs (e.g., temperature sensor, VCC/2), enabling comprehensive on-chip signal monitoring without external multiplexers.
What low-power modes are available on the MSP430FG6625IZQWR, and what is the current draw in LPM3.5?
The MSP430FG6625IZQWR offers five low-power modes including LPM3.5 (RTC active with crystal). In LPM3.5, it draws 0.9 µA at 3.0 V - sufficient to maintain accurate timekeeping and wake on alarm while preserving RAM and peripheral register states for rapid resumption of measurement tasks.
Is the MSP430FG6625IZQWR pin-compatible with other devices in the FG662x family?
Yes, the MSP430FG6625IZQWR is pin-compatible with MSP430FG6626IZQW and MSP430FG642xIZQW variants in the 113-pin ZQW package.
