Product details
Overview
MSP430FG6626IZQWR 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 full-speed USB PHY and power system, and LCD driver supporting up to 160 segments - designed for portable measurement systems requiring high analog integration and extended battery life.
For engineers reviewing the MSP430FG6626IZQWR datasheet, MSP430FG6626IZQWR pinout, MSP430FG6626IZQWR application, or MSP430FG6626IZQWR equivalent, key selection considerations include USB-enabled data acquisition, low-power RTC operation in LPM3.5 (0.9 µA), 73 GPIOs in MicroStar Junior™ BGA, and compatibility with TI's MSP430Ware™ ecosystem and MSP-TS430PZ100AUSB development board.
Technical Context
The MSP430FG6626IZQWR 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 with automatic frequency stabilization.
It integrates a dedicated USB subsystem including USB-PHY, 3.3-V/1.8-V regulated USB power, USB-PLL, and eight IN/OUT endpoints - all operating independently of the main core supply. The analog signal chain includes two rail-to-rail op-amps, quad ground switches, voltage comparator, and CTSD16 ADC with internal reference and selectable single-ended/differential input configuration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FG6626IPZ | Same core, peripherals, and memory; differs only in 100-pin LQFP (PZ) package vs. 113-pin MicroStar Junior™ BGA (ZQW) | Requires PCB redesign due to different footprint, pitch, and thermal pad; no change in firmware or schematic functionality | Select IPZ for prototyping or manual assembly; ZQW preferred for space-constrained, high-density production designs |
| MSP430FG6426IZQW | Omits integrated USB PHY, USB power system, and USB-PLL; identical ADC, DAC, op-amps, timers, and LCD driver | Suitable where USB is unnecessary (e.g., Bluetooth/Wi-Fi gateway, isolated sensor node); reduces BOM cost and layout complexity | Choose FG6426IZQW when USB connectivity is handled externally or omitted entirely - retains same analog integration and low-power profile |
Compared with MSP430FG6626IPZ, the ZQW variant offers higher I/O density and improved thermal performance in compact layouts; compared with MSP430FG6426IZQW, the FG6626IZQW adds full-speed USB capability without increasing power consumption in active or standby modes.

Does the MSP430FG6626IZQWR support full-speed USB without external components?
Yes, the MSP430FG6626IZQWR integrates a full-speed USB 2.0 PHY, USB-PLL, and dual regulated power supplies (3.3 V and 1.8 V), enabling direct USB connectivity with only passive ESD protection and series resistors required - no external transceiver or voltage translators needed.
What are the key low-power modes supported by the MSP430FG6626IZQWR?
The MSP430FG6626IZQWR supports five low-power modes: LPM3 (3.4 µA @ 3.0 V) with watchdog and crystal RTC active; LPM3.5 (0.9 µA @ 3.0 V) with RTC-only operation and full RAM retention; and LPM4.5 (0.2 µA @ 3.0 V) deep shutdown with RTC disabled but backup registers preserved.
Can the MSP430FG6626IZQWR drive an LCD display directly?
Yes, the MSP430FG6626IZQWR includes an integrated LCD_B module supporting up to 160 segments with programmable contrast control, internal charge pump, and static/multiplexed drive capability - eliminating the need for external LCD bias generators or driver ICs.
