Texas Instruments MSP430F415IRTDR

Overview

MSP430F415IRTDR from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller with 16KB flash, 512B RAM, integrated 96-segment LCD driver, on-chip comparator, and FLL+ clock system. It operates from 1.8 V to 3.6 V and supports five power-saving modes, enabling sub-6 μs wake-up from standby - ideal for battery-powered handheld meters and industrial sensor interfaces.

For engineers reviewing the MSP430F415IRTDR datasheet, MSP430F415IRTDR pinout, MSP430F415IRTDR application, or MSP430F415IRTDR equivalent, key selection criteria include its QFN-64 (RTD) package, Timer_A5 with five capture/compare registers, programmable SVS voltage monitoring, and JTAG + BSL serial programming capability.

Technical Context

The MSP430F415IRTDR implements a dual-timer architecture: Timer0_A3 (3 CC registers) for basic timing and Timer1_A5 (5 CC registers) for advanced capture/compare operations - both supporting PWM, input capture, and interval timing. Its FLL+ module locks the DCO to ACLK (32.768 kHz crystal) to generate stable MCLK up to 8 MHz without external high-frequency crystals.

It features separate analog (AVCC/AVSS1/AVSS2) and digital (DVCC/DVSS) supply domains, enabling precise LCD bias generation and noise-isolated analog sensing. The SVSIN pin (P6.7) allows external brownout threshold adjustment, while the comparator_A supports rail-to-rail inputs and configurable hysteresis for sensor signal conditioning.

FAQ

What is the maximum operating frequency of the MSP430F415IRTDR?

The MSP430F415IRTDR supports a maximum MCLK frequency of 8 MHz, generated by the FLL+ module locked to the 32.768 kHz watch crystal. This enables deterministic 125-ns instruction cycles for real-time sensor processing and LCD refresh without external high-frequency oscillators. The MSP430F415IRTDR achieves this performance while maintaining ultralow power consumption across all operating modes.

Does the MSP430F415IRTDR support in-system programming?

Yes, the MSP430F415IRTDR supports three in-system programming methods: JTAG interface (TCK/TMS/TDI/TDO pins), UART-based Bootstrap Loader (BSL) using P1.0/P1.1, and CPU-controlled flash writes. The BSL enables field firmware updates without debug hardware, and all methods support full flash and information memory erase/write with security fuse protection. This flexibility makes the MSP430F415IRTDR suitable for both development and deployed device maintenance.

How many LCD segments can the MSP430F415IRTDR drive, and what mux configurations are supported?

The MSP430F415IRTDR drives up to 96 segments using its integrated LCD controller with COM0–COM3 and S0–S31 pins. It supports static, 2-mux, 3-mux, and 4-mux configurations - selectable via LCDCTL register bits. The 4-mux mode enables higher contrast and lower power per segment, while static mode provides fastest update rates for simple displays. All configurations operate without external charge pumps or bias generators.

What is the function of the SVSIN pin (P6.7) on the MSP430F415IRTDR?

The SVSIN pin (P6.7) on the MSP430F415IRTDR serves as an analog input for the Supply Voltage Supervisor, allowing external resistor-divider configuration of the brownout detection threshold. Unlike fixed-threshold variants, this pin enables precise, application-specific reset voltage setting - critical for systems powered by variable sources like aging batteries or unregulated adapters. The MSP430F415IRTDR uses this input to trigger SVSOUT (P1.3) or initiate POR when voltage falls below the programmed level.

Is the MSP430F415IRTDR pin-compatible with other devices in the MSP430x41x family?

Yes, the MSP430F415IRTDR shares identical pinout and package (64-pin QFN RTD) with MSP430F413IRTDR, MSP430F417IRTDR, and all RTD-packaged MSP430x41x variants. Signal assignments, power/ground locations, and JTAG/BSL pin positions are fully aligned - enabling direct PCB reuse across memory variants. However, functional differences (e.g., Timer1_A5 presence, flash size) require firmware adaptation despite mechanical compatibility.
