Product details
Overview
MSP430FG6425IZQWR 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 64 KB flash/10 KB SRAM - designed for portable measurement systems such as handheld medical diagnostic meters and industrial field testers.
For engineers reviewing the MSP430FG6425IZQWR datasheet, MSP430FG6425IZQWR pinout, MSP430FG6425IZQWR application, or MSP430FG6425IZQWR equivalent, key selection criteria include its 113-pin MicroStar Junior™ BGA package, absence of integrated USB (distinguishing it from FG662x variants), LPM3.5 RTC operation at 0.9 µA, and dual op-amp signal conditioning capability in battery-constrained monitoring designs.
Technical Context
The MSP430FG6425IZQWR implements a 16-bit RISC CPU with extended memory addressing, digitally controlled oscillator (DCO), and unified clock system supporting FLL stabilization, VLO, REFO, XT1 (32 kHz), and XT2 (up to 32 MHz). Its low-power architecture enables wake-up from standby in 3 µs and supports five distinct low-power modes including LPM3.5 (RTC active with crystal) and LPM4.5 (0.2 µA shutdown).
It integrates four USCI modules (two UART/IrDA/SPI-capable USCI_A and two I²C/SPI-capable USCI_B), six-channel DMA, hardware multiplier for 32-bit operations, and a dedicated backup subsystem with 8-byte RAM, 32-kHz oscillator, and RTC - all powered by a separate voltage domain to maintain timekeeping during main supply loss.
