Product details
Overview
MSP430F417IRTDR from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller featuring 32KB flash, 1KB RAM, integrated 96-segment LCD driver, on-chip comparator, and programmable supply voltage supervisor. It operates from 1.8 V to 3.6 V and supports five power-saving modes, enabling sub-6 μs wake-up - ideal for battery-powered handheld meters and industrial sensor displays.
For engineers reviewing the MSP430F417IRTDR datasheet, MSP430F417IRTDR pinout, MSP430F417IRTDR application, or MSP430F417IRTDR equivalent, key selection criteria include its QFN-64 (RTD) package, Timer_A5 with five capture/compare registers, FLL+ clock system, brownout detection, and BSL-enabled in-system programming without external voltage.
Technical Context
The MSP430F417IRTDR implements a 16-bit CPU with 125-ns instruction cycle time, constant generators, and seven addressing modes for high code efficiency. Its dual-timer architecture includes Timer0_A3 (3 CC registers) and Timer1_A5 (5 CC registers), both supporting capture, compare, PWM, and interval timing functions.
It integrates dedicated analog and digital supply domains (AVCC/AVSS1/AVSS2, DVCC/DVSS), enabling precise LCD bias generation and independent SVS monitoring. The FLL+ module locks DCO frequency to XT1 (32.768 kHz) reference, delivering stable MCLK up to 8 MHz while maintaining <6 μs active-mode wake-up from LPM4.

FAQ
What is the maximum operating frequency of the MSP430F417IRTDR?
The MSP430F417IRTDR supports a maximum MCLK frequency of 8 MHz, achieved via the FLL+ module locking the DCO to the 32.768 kHz XT1 crystal reference. This yields a 125-ns instruction cycle time for the 16-bit RISC core, sufficient for real-time sensor processing and LCD refresh without external clock sources.
Does the MSP430F417IRTDR support in-system programming without a JTAG debugger?
Yes, the MSP430F417IRTDR includes a factory-programmed Bootstrap Loader (BSL) accessible via UART on P1.0 (TX) and P1.1 (RX). This allows full flash programming and verification using only a 3.3 V UART interface and user-defined password protection - no JTAG hardware is required for field firmware updates.
How many LCD segments can the MSP430F417IRTDR drive, and what multiplexing options are supported?
The MSP430F417IRTDR drives up to 96 segments using its integrated LCD controller with support for 1-, 2-, 3-, or 4-multiplex configurations. It provides four common outputs (COM0–COM3) and programmable internal voltage dividers (V1–V5), enabling direct connection to static, 2-mux, or 4-mux LCD glass without external bias components.
What are the key differences between the MSP430F417IRTDR and MSP430F413IRTDR?
The MSP430F417IRTDR features 32KB flash and 1KB RAM versus the MSP430F413IRTDR's 8KB flash and 256B RAM. Both share the same QFN-64 package, Timer1_A5, 96-segment LCD driver, and SVS functionality. The MSP430F417IRTDR is selected for applications requiring larger firmware storage and more runtime data buffering.
Is the MSP430F417IRTDR qualified for industrial temperature range operation?
Yes, the MSP430F417IRTDR is specified for operation from −40°C to +85°C ambient temperature. Its FLL+ clock system maintains stable MCLK/SMCLK/ACLK across this range, and the integrated SVS monitors supply integrity under thermal stress - meeting requirements for industrial panel meters and outdoor environmental sensors.
