Product details
Overview
MSP430FG6626IPZ 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, LCD driver for up to 160 segments, and 128KB flash/8KB+2KB SRAM. It operates from 1.8 V to 3.6 V and targets battery-powered precision measurement systems.
For engineers reviewing the MSP430FG6626IPZ datasheet, MSP430FG6626IPZ pinout, MSP430FG6626IPZ application, or MSP430FG6626IPZ equivalent, key selection criteria include USB integration, low-power RTC in LPM3.5 (0.9 µA), 100-pin LQFP package compatibility, and analog signal chain performance for handheld metrology.
Technical Context
The MSP430FG6626IPZ implements a 16-bit RISC CPU with constant generators and a digitally controlled oscillator (DCO) enabling sub-5-µs wake-up from low-power modes. Its unified clock system includes FLL stabilization, VLO, REFO, XT1 (32 kHz), and XT2 (up to 32 MHz) sources.
It integrates five low-power operating modes, including LPM3.5 (RTC active with crystal, 0.9 µA at 3.0 V) and LPM4.5 (0.2 µA shutdown). The auxiliary supply subsystem powers the RTC, backup memory (8 bytes), and 32-kHz oscillator independently.

FAQ
What is the maximum system clock frequency supported by the MSP430FG6626IPZ?
The MSP430FG6626IPZ supports a maximum system clock frequency of 20 MHz. This is achieved using the integrated FLL with XT2 crystal oscillator (up to 32 MHz input) or internal DCO calibration. Operation at 20 MHz enables real-time processing of high-resolution ADC samples and fast USB data transfers while maintaining ultra-low active current (250 µA/MHz at 3.0 V).
Does the MSP430FG6626IPZ include an integrated USB transceiver?
Yes, the MSP430FG6626IPZ includes a fully integrated USB 2.0 full-speed (12 Mbps) transceiver (PHY), USB-PLL, and dual regulated power supplies (3.3 V and 1.8 V). This eliminates the need for external USB interface components, reducing PCB area and BOM cost. The DP and DM pins (PU.0 and PU.1) connect directly to the USB connector with appropriate ESD protection.
How many analog inputs does the sigma-delta ADC on the MSP430FG6626IPZ support?
The MSP430FG6626IPZ features a 16-bit continuous-time sigma-delta ADC with 10 external analog inputs - six configured as single-ended and four configurable as either single-ended or differential pairs. Additionally, five internal inputs (e.g., temperature sensor, VCC/2, VREF) are available, bringing total ADC input capability to 15 channels as documented in the device comparison table.
What is the purpose of the auxiliary supply subsystem in the MSP430FG6626IPZ?
The auxiliary supply subsystem in the MSP430FG6626IPZ powers the RTC, 32-kHz low-frequency oscillator (XT1), and 8-byte backup RAM independently from the main DVCC domain. This allows the RTC to maintain timekeeping during main power removal or deep shutdown (LPM3.5/LPM4.5), enabling wake-up events and data retention without draining the primary battery.
Can the MSP430FG6626IPZ operate without an external crystal?
Yes, the MSP430FG6626IPZ can operate without an external crystal using its internal digitally controlled oscillator (DCO) calibrated by the FLL against the low-frequency REFO (32.768 kHz) or VLO (10 kHz) sources. While this supports basic functionality and low-power modes, full USB operation and precise RTC timing require the 32-kHz XT1 crystal; high-accuracy ADC conversions benefit from XT2 stability.
