Texas Instruments MSP430F2471TRGCT

Overview

MSP430F2471TRGCT from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 32KB+256B flash memory, 4KB RAM, a 16-bit Timer_B with seven capture/compare registers and shadow registers, four USCI modules (dual UART/IrDA/SPI + dual I²C/SPI), and on-chip comparator. It operates across 1.8 V–3.6 V and targets battery-powered sensor nodes and portable instrumentation.

For engineers reviewing the MSP430F2471TRGCT datasheet, MSP430F2471TRGCT pinout, MSP430F2471TRGCT application, or MSP430F2471TRGCT equivalent, key selection criteria include its 64-pin QFN (RGC) package, absence of ADC12 (per F24x1 family designation), ultra-fast wake-up (<1 µs), and dual USCI_A/USCI_B support for concurrent serial protocols in space-constrained designs.

Technical Context

The MSP430F2471TRGCT implements a calibrated DCO enabling 16 MHz operation without external crystal, paired with programmable clock system supporting MCLK, SMCLK, and ACLK sourced from internal oscillators or XT1/XT2 crystals. Its USCI_A0/A1 modules support enhanced UART with auto-baud detection and IrDA encoding, while USCI_B0/B1 provide hardware I²C master/slave and synchronous SPI.

It integrates a 15/16-bit Timer_A with three capture/compare registers and a 16-bit Timer_B with seven capture/compare registers plus shadow registers-enabling simultaneous PWM generation, input capture, and event timing across multiple channels. The device lacks ADC12 per F24x1 specification but retains full analog comparator (Comp_A+) and SVS/SVM circuitry.

FAQ

Does the MSP430F2471TRGCT include an integrated ADC?

No, the MSP430F2471TRGCT does not include the ADC12 module. As an F24x1-series device, it omits the 12-bit analog-to-digital converter present in F24x variants like MSP430F247TRGCT. However, it retains the full Comp_A+ analog comparator, SVS/SVM, and all digital peripherals-including Timer_A, Timer_B, and four USCI modules-making it suitable for applications relying on external ADCs or comparator-based threshold detection. The MSP430F2471TRGCT datasheet explicitly confirms this distinction in its family description.

What is the maximum operating frequency of the MSP430F2471TRGCT?

The MSP430F2471TRGCT supports up to 16 MHz operation using its calibrated digitally controlled oscillator (DCO). This frequency is achievable without external crystals, though optional XT1 (32 kHz) and XT2 (up to 16 MHz) crystal oscillators can be used for higher precision timing. The 16 MHz DCO performance is specified across the full 1.8 V–3.6 V supply range and –40°C to +105°C temperature range, as confirmed in the SLAS547I datasheet's electrical characteristics tables. All MSP430F2471TRGCT timing-critical functions-including Timer_B PWM and USCI baud generation-scale correctly at this rate.

Is the MSP430F2471TRGCT pin-compatible with other MSP430F24x devices?

Yes, the MSP430F2471TRGCT shares identical pinout and package (64-pin QFN, RGC) with all MSP430F24x and MSP430F24x1 family members, including MSP430F247TRGCT, MSP430F2491TRGCT, and MSP430F2410TRGCT. Pin functions are fully aligned per Table 3 of SLAS547I, enabling drop-in replacement where ADC12 is not required. This compatibility simplifies design reuse and migration-e.g., upgrading firmware from MSP430F2471TRGCT to MSP430F247TRGCT requires only flash reprogramming and no PCB changes.

How does the MSP430F2471TRGCT support low-power system design?

The MSP430F2471TRGCT supports low-power system design through five configurable low-power modes (LPM0–LPM4), sub-µA standby current (0.3 µA at VLO), and ultra-fast wake-up (<1 µs). Its DCO enables immediate clock stabilization after wake-up, eliminating crystal startup delays. Peripheral modules like USCI and Timer_B retain configuration during LPM3, allowing autonomous UART receive or PWM timing without CPU intervention. These features collectively minimize active time and maximize sleep duration-critical for battery life in MSP430F2471TRGCT-based sensor endpoints and portable instruments.

What development tools are recommended for the MSP430F2471TRGCT?

Texas Instruments recommends the MSP-FET430UIF (USB JTAG programmer/debugger) and MSP-TS430RGC64 (target socket board for RGC-package devices) for MSP430F2471TRGCT development. The device's integrated Embedded Emulation Module (EEM) supports full-speed debugging, flash programming, and real-time register inspection. Code Composer Studio v6+ and naken430gcc provide complete toolchain support. All MSP430F2471TRGCT-specific peripheral drivers and example projects are available in TI's MSP430Ware software library, ensuring rapid prototyping and validation of USCI, Timer_B, and comparator functionality.
