Product details
Overview
MSP430FG4250IRGZT from Texas Instruments is an ultralow-power 16-bit mixed-signal microcontroller featuring 16KB+256B Flash, 256B RAM, a 16-bit sigma-delta ADC with internal reference and five differential analog inputs, a 12-bit DAC, two configurable operational amplifiers, and integrated LCD driver supporting up to 56 segments. It operates from 1.8 V to 3.6 V and targets battery-powered sensor systems and portable instrumentation.
For engineers reviewing the MSP430FG4250IRGZT datasheet, MSP430FG4250IRGZT pinout, MSP430FG4250IRGZT application, or MSP430FG4250IRGZT equivalent, key selection criteria include active-mode current (250 μA at 1 MHz, 2.2 V), wake-up time from standby (<6 μs), LCD segment drive capability (56 segments), sigma-delta ADC resolution (16-bit), and QFN-48 package compatibility with space-constrained designs.
Technical Context
The MSP430FG4250IRGZT integrates a 16-bit RISC CPU with constant generators and 16 general-purpose registers, enabling single-cycle instruction execution. Its FLL+ clock system supports ACLK (32768 Hz crystal), MCLK (CPU clock), and SMCLK (peripheral clock), with DCO stabilization in under 6 μs for rapid low-power mode exit.
Peripherals include Timer_A3 with three capture/compare registers, SD16_A 16-bit sigma-delta ADC with programmable gain and internal temperature sensor, DAC12 voltage-output DAC, and dual op-amps (OA0/OA1) with software-selectable input multiplexing and feedback paths-enabling front-end analog signal conditioning prior to conversion.
