Texas Instruments MSP430F247TPMR

Overview

MSP430F247TPMR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 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 SPI/I²C), and on-chip comparator. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and portable instrumentation.

For engineers reviewing the MSP430F247TPMR datasheet, MSP430F247TPMR pinout, MSP430F247TPMR application, or MSP430F247TPMR equivalent, key selection criteria include its 64-pin QFP package, integrated ADC12 with internal reference and autoscan, dual USCI_A/B for concurrent serial protocols, ultra-fast wake-up (<1 µs), and support for both XT1 (32 kHz) and XT2 (up to 16 MHz) crystal oscillators.

Technical Context

The MSP430F247TPMR implements a 16-bit CPU with constant generators and hardware multiplier for optimized code efficiency in low-power embedded control. Its basic clock module integrates DCO with four factory-calibrated frequencies (±1%), LF oscillator, and support for external crystals (XT1 and XT2) or resonators.

It features two independent universal serial communication interfaces: USCI_A0/A1 support enhanced UART (auto-baud, IrDA), SPI, and LIN; USCI_B0/B1 support synchronous SPI and I²C. The ADC12 module includes sample-and-hold, internal reference, and autoscan-enabling continuous analog monitoring without CPU intervention.

FAQ

What is the maximum operating frequency of the MSP430F247TPMR?

The MSP430F247TPMR supports a maximum system clock (MCLK) frequency of 16 MHz using the XT2 crystal oscillator or calibrated DCO. Its 16-bit RISC core executes instructions at 62.5 ns per cycle, enabling real-time response in time-critical sensor and control loops. The device maintains full functionality-including ADC12 sampling and USCI baud rate generation-at this speed.

Does the MSP430F247TPMR include an integrated ADC?

Yes, the MSP430F247TPMR integrates a 12-bit successive-approximation ADC (ADC12) with 8 external input channels (A0–A7), internal reference (1.5 V or 2.5 V), sample-and-hold, and autoscan capability. This ADC is fully functional and documented in the SLAS547I datasheet, distinguishing it from the MSP430F24x1 series where ADC12 is omitted.

What package type is used for the MSP430F247TPMR?

The MSP430F247TPMR is supplied in a 64-pin Plastic Quad Flat Package (QFP), designated by the "PM" suffix and RoHS-compliant. Its 10 mm × 10 mm footprint with 0.5 mm lead pitch is compatible with standard surface-mount assembly processes and matches pinout with other MSP430F24x family members in PM and RGC packages.

Can the MSP430F247TPMR operate from a single 3.3 V supply?

Yes, the MSP430F247TPMR operates across a supply range of 1.8 V to 3.6 V, making it fully compatible with standard 3.3 V LDOs or direct connection to regulated 3.3 V rails. At 3.3 V, it achieves improved noise margin and ADC SNR while maintaining ultra-low active current (≤340 µA at 1 MHz), supporting robust operation in noisy industrial environments.

How many USCI modules does the MSP430F247TPMR support?

The MSP430F247TPMR supports four Universal Serial Communication Interfaces: USCI_A0 and USCI_A1 (each configurable as UART, IrDA, or SPI), and USCI_B0 and USCI_B1 (each configurable as SPI or I²C). This enables concurrent use of multiple serial protocols - for example, UART for host communication, I²C for sensor reading, and SPI for external memory - without software multiplexing.
