Product details
Overview
MSP430F247TPM from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 32KB+256B flash memory, 4KB RAM, a 12-bit ADC with 8 channels, two 16-bit timers (Timer_A with 3 capture/compare registers and Timer_B with 7 plus shadow registers), four USCI modules (dual UART/IrDA/SPI + dual I²C/SPI), and on-chip comparator - deployed in portable sensor systems and industrial control nodes requiring sub-1µs wake-up and battery life extension.
For engineers reviewing the MSP430F247TPM datasheet, MSP430F247TPM pinout, MSP430F247TPM application, or MSP430F247TPM equivalent, key selection criteria include its 64-pin QFP package, ADC12 integration, dual USCI_A/B support, SVS/SVM supply monitoring, and compatibility with MSP-FET430U64 and MSP-TS430PM64 development tools.
Technical Context
The MSP430F247TPM implements a calibrated DCO enabling 16-MHz operation without external crystals, supports dual crystal oscillators (XT1 for 32-kHz watch crystals and XT2 for high-frequency up to 16 MHz), and integrates a hardware multiplier for efficient math-intensive firmware. Its basic clock module provides programmable ACLK, SMCLK, and MCLK routing across peripherals.
It features two independent USCI_A modules (UART/IrDA/SPI) and two USCI_B modules (I²C/SPI), each with separate clock sources and autonomous operation. The ADC12 module includes internal reference, sample-and-hold, and autoscan - all directly controllable via DMA or interrupt-driven sequences without CPU intervention.

FAQ
What is the maximum operating frequency of the MSP430F247TPM?
The MSP430F247TPM supports up to 16 MHz system clock via its calibrated DCO or external XT2 crystal oscillator. This frequency is achievable across the full 1.8 V to 3.6 V supply range and enables deterministic execution of time-critical tasks such as real-time sensor sampling and communication protocol handling. The MSP430F247TPM maintains full peripheral functionality-including ADC12 conversions and USCI baud rate generation-at this speed.
Does the MSP430F247TPM include an integrated ADC, and what are its key capabilities?
Yes, the MSP430F247TPM integrates a 12-bit ADC (ADC12) with eight input channels, internal reference voltage generator, sample-and-hold circuitry, and autoscan mode. It supports both single-channel and sequence conversions with configurable sample timing, and its conversion clock (ADC12CLK) can be sourced independently from MCLK, SMCLK, or ACLK. These features make the MSP430F247TPM suitable for precision analog measurement in applications like energy metering and environmental sensing.
Is the MSP430F247TPM pin-compatible with other devices in the MSP430F24x family?
Yes, the MSP430F247TPM is pin-compatible with MSP430F248TPM, MSP430F249TPM, and MSP430F2410TPM in the 64-pin QFP (PM) package. All share identical pin functions, electrical characteristics, and peripheral mappings - allowing hardware reuse across variants when scaling flash capacity or adjusting feature sets without PCB redesign.
What development tools are officially supported for the MSP430F247TPM?
Texas Instruments officially supports the MSP-FET430U64 (target board with PM socket), MSP-TS430PM64 (standalone target board), and MSP-FET430UIF (USB debugging interface) for the MSP430F247TPM. These tools provide full JTAG-based debugging, flash programming, and real-time trace - and are validated for use with Code Composer Studio and IAR Embedded Workbench IDEs.
How does the MSP430F247TPM handle power supply monitoring and brownout protection?
The MSP430F247TPM includes a supply voltage supervisor (SVS) with programmable threshold levels and a dedicated brownout detector (BOR). The SVS can generate interrupts or force reset based on DVCC voltage deviations, while the BOR ensures reliable startup and shutdown behavior. Both features operate independently of CPU activity and remain functional in all low-power modes - critical for robust operation in industrial environments with unstable power rails.
