Texas Instruments MSP430F2471TPM

Overview

MSP430F2471TPM from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 32KB+256B flash, 4KB RAM, and a 16-bit Timer_B with seven capture/compare registers. It features two USCI modules (UART/IrDA/SPI/I²C), a comparator, supply voltage supervisor, and operates from 1.8 V to 3.6 V. It targets battery-powered sensor nodes and portable instrumentation requiring sub-1µs wake-up and precise analog measurement.

For engineers reviewing the MSP430F2471TPM datasheet, MSP430F2471TPM pinout, MSP430F2471TPM application, or MSP430F2471TPM equivalent, key selection criteria include ADC12 absence, 64-pin QFP package compatibility, ultra-low active/standby current, JTAG debug support, and dual-USCI serial interface capability for mixed-protocol sensor gateways.

Technical Context

The MSP430F2471TPM implements the MSP430x2xx architecture with a 16-bit CPU, constant generators, and five low-power modes optimized for extended battery life. Its basic clock system includes a calibrated DCO (up to 16 MHz), internal LF oscillator, 32-kHz crystal support, and external clock/resistor options.

This device belongs to the MSP430F24x1 variant group: identical to MSP430F24x but with the ADC12 module omitted. It retains full Timer_A (3 CC), Timer_B (7 CC with shadow registers), Comparator_A+, USCI_A0/A1/B0/B1, and 48 I/O pins - enabling high-functionality control without on-chip 12-bit A/D conversion.

FAQ

Does the MSP430F2471TPM include a 12-bit analog-to-digital converter?

No, the MSP430F2471TPM is part of the MSP430F24x1 variant series, which explicitly omits the ADC12 module. This distinguishes it from the MSP430F247TPM and other F24x devices that include the 12-bit ADC. The MSP430F2471TPM retains the Comparator_A+ module for threshold-based analog decisions but requires external ADCs for digitization tasks. All documentation confirms ADC12 is not implemented on the MSP430F2471TPM die.

What debug interfaces does the MSP430F2471TPM support?

The MSP430F2471TPM supports full IEEE 1149.1 JTAG debugging via dedicated TCK, TMS, TDI, and TDO pins (Pins 57, 56, 55, 54). It also includes an embedded emulation module (EEM) compatible with TI's MSP-FET430UIF and MSP-FET430U64 tools. No SWD or cJTAG is supported - JTAG is the sole hardware debug interface for the MSP430F2471TPM.

Can the MSP430F2471TPM operate from a 1.8-V supply?

Yes, the MSP430F2471TPM supports a minimum supply voltage of 1.8 V across its full operating temperature range (–40°C to 105°C). At 1.8 V, it maintains full functionality including 16-MHz DCO operation (calibrated), USCI communication, Timer_B shadow register updates, and Comparator_A+ operation - verified in TI's SLAS547I datasheet electrical characteristics tables.

What is the maximum clock frequency achievable with the internal DCO on the MSP430F2471TPM?

The MSP430F2471TPM's digitally controlled oscillator (DCO) is factory-calibrated to operate up to 16 MHz with ±1% accuracy across voltage and temperature when using one of the four internal frequency settings. This maximum frequency is fully supported in active mode and enables high-speed serial communication (e.g., 1-Mbps UART) and fast computational throughput without external crystals.

Is the MSP430F2471TPM pin-compatible with the MSP430F247TPM?

Yes, the MSP430F2471TPM and MSP430F247TPM share identical 64-pin QFP (PM) packages and pinouts - including identical power, I/O, JTAG, and peripheral signal assignments. The only functional difference is the absence of ADC12 circuitry in the MSP430F2471TPM; all other peripherals, memory maps, and register layouts are binary-compatible, allowing drop-in replacement where ADC12 is unused.
