Texas Instruments MSP430F2471TPMR

Overview

MSP430F2471TPMR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 32KB+256B flash memory, 4KB RAM, dual 16-bit timers (Timer_A with 3 capture/compare registers and Timer_B with 7 capture/compare registers with shadow registers), four USCI modules (two UART/IrDA/SPI and two SPI/I²C), 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 MSP430F2471TPMR datasheet, MSP430F2471TPMR pinout, MSP430F2471TPMR application, or MSP430F2471TPMR equivalent, key selection criteria include ADC12 absence, 64-pin QFP package compatibility, ultra-fast wake-up (<1 µs), and support for dual USCI_A/USCI_B interfaces in mixed-protocol systems.

Technical Context

The MSP430F2471TPMR implements a calibrated DCO with four factory-trimmed frequencies (±1%), supports internal LF oscillator, 32-kHz crystal, and external digital clock sources, and integrates a hardware multiplier for efficient math operations. Its basic clock module enables flexible clock routing to MCLK, SMCLK, and ACLK domains.

As an MSP430F24x1-series device, it excludes the ADC12 module entirely-unlike MSP430F247-while retaining full Timer_B7, dual USCI_A/USCI_B, comparator, SVS/SVM, and BSL functionality. All I/O pins support interrupt capability and configurable pull-up/down resistors.

FAQ

Does MSP430F2471TPMR include an integrated ADC?

No, the MSP430F2471TPMR explicitly omits the ADC12 module per TI's MSP430F24x(1) designation. It shares all other peripherals-including Timer_A, Timer_B7, four USCI modules, comparator, and SVS-with the MSP430F247, but analog-to-digital conversion must be implemented externally. This omission reduces die size, cost, and power consumption in applications that rely solely on digital sensors or external ADCs.

What is the maximum operating frequency of MSP430F2471TPMR?

The MSP430F2471TPMR supports internal DCO frequencies up to 16 MHz, with four factory-calibrated settings accurate to ±1% across voltage and temperature. When using external crystals (XT1 or XT2), the system can derive precise clocks-for example, 32.768 kHz from a watch crystal for RTC functions or up to 8 MHz from a high-frequency crystal-while maintaining full low-power mode compatibility.

Is MSP430F2471TPMR pin-compatible with MSP430F247TPMR?

Yes, the MSP430F2471TPMR is fully pin-compatible with the MSP430F247TPMR in the 64-pin QFP (PM) package. Both share identical pin assignments, electrical characteristics, and package dimensions. The only functional difference is the absence of ADC12 in the MSP430F2471TPMR, meaning unused ADC-related pins (e.g., A0–A7 on Port 6) function as general-purpose I/O in the MSP430F2471TPMR.

Which development tools support MSP430F2471TPMR programming and debug?

The MSP430F2471TPMR is supported by TI's standard MSP430 toolchain: MSP-FET430UIF (USB JTAG), MSP-FET430PIF (parallel port), and standalone programmers like MSP-GANG430. Target boards such as MSP-TS430PM64 provide socketed 64-pin QFP access, and Code Composer Studio v6+ includes device-specific drivers, startup files, and example projects validated for the MSP430F24x1 series.

How does the absence of ADC12 affect power consumption in MSP430F2471TPMR?

The absence of ADC12 reduces active-mode current by approximately 20–30 µA and eliminates ADC-related leakage paths in low-power modes. While the base active current remains 270 µA at 1 MHz/2.2 V, removing the ADC12 module lowers total system power in always-on monitoring applications-especially when combined with the comparator for threshold detection instead of periodic ADC sampling. No additional power-supply sequencing or biasing is required.
