Product details
Overview
MSP430FG6625IPZR 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 LCD driver supporting up to 160 segments. It operates from 1.8 V to 3.6 V, delivers 250 µA/MHz active current at 3.0 V, and targets portable measurement systems requiring high analog integration and extended battery life.
For engineers reviewing the MSP430FG6625IPZR datasheet, MSP430FG6625IPZR pinout, MSP430FG6625IPZR application, or MSP430FG6625IPZR equivalent, key selection considerations include USB-enabled data acquisition, low-power sensor signal chain design, LCD-based human interface implementation, and compatibility with TI's MSP-TS430PZ100AUSB development board.
Technical Context
The MSP430FG6625IPZR 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, while the auxiliary supply subsystem powers RTC and backup RAM independently.
It integrates four USCI modules (two UART/IrDA/SPI and two SPI/I²C), six-channel DMA, hardware multiplier for 32-bit operations, and intelligent peripherals including four 16-bit timers (TA0 with 5 CC, TA1/TA2 with 3 CC each, TB0 with 7 CC), RTC with calibration logic, and voltage comparator with programmable hysteresis.

FAQ
What is the maximum system clock frequency supported by the MSP430FG6625IPZR?
The MSP430FG6625IPZR 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 calibration. This enables real-time signal processing for high-speed ADC sampling and USB packet handling without external clock synthesis.
Does the MSP430FG6625IPZR require an external USB transceiver?
No, the MSP430FG6625IPZR integrates a full-speed USB 2.0 PHY, 3.3-V and 1.8-V USB power system, and USB-PLL - eliminating the need for an external transceiver. Only standard USB termination resistors (1.5-kΩ pull-up on DP and 22-Ω series on DP/DM) and decoupling capacitors are required for compliance.
How many analog inputs does the sigma-delta ADC in the MSP430FG6625IPZR support?
The MSP430FG6625IPZR features a 16-bit continuous-time sigma-delta ADC with 10 external analog inputs: 6 single-ended and 4 configurable as either single-ended or differential. Additionally, it supports 5 internal inputs including temperature sensor, VCC/2, and reference voltages - enabling comprehensive on-chip signal monitoring.
What is the function of the auxiliary supply subsystem in the MSP430FG6625IPZR?
The auxiliary supply subsystem in the MSP430FG6625IPZR powers the 32-kHz low-frequency oscillator (XT1), RTC module, and 8-byte backup RAM independently from the main DVCC rail. This ensures continuous timekeeping and critical state retention during main power loss or deep shutdown modes like LPM3.5 and LPM4.5.
Can the MSP430FG6625IPZR drive a 160-segment LCD without external components?
Yes, the MSP430FG6625IPZR integrates the LCD_B module with built-in charge pump, contrast control, and up to 160 segment drivers. When configured with appropriate external capacitors (e.g., LCDCAP/R33 to DVSS), it drives static or multiplexed LCDs directly - eliminating the need for external LCD controllers or bias generators.
