Texas Instruments MSP430F247TRGCR

Overview

MSP430F247TRGCR from Texas Instruments is an ultra-low-power 16-bit mixed-signal 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 capture/compare registers with shadow registers), four USCI modules (two UART/IrDA/SPI and two SPI/I²C), and operation across 1.8 V to 3.6 V supply. It targets battery-powered sensor nodes and portable measurement systems requiring fast wake-up (<1 µs) and long-term energy efficiency.

For engineers reviewing the MSP430F247TRGCR datasheet, MSP430F247TRGCR pinout, MSP430F247TRGCR application, or MSP430F247TRGCR equivalent, key selection considerations include its 64-pin QFN (RGC) package, integrated SVS/SVM, programmable brownout detection, on-chip comparator, and dual USCI_A/USCI_B support for concurrent serial protocols in space-constrained industrial sensing designs.

Technical Context

The MSP430F247TRGCR implements a 16-bit RISC CPU with constant generators and hardware multiplier, enabling high code efficiency in low-clock-rate embedded control. Its basic clock system integrates a calibrated DCO (±1% over temperature/voltage), LF oscillator, and support for external crystals (XT1 up to 32 kHz, XT2 up to 16 MHz).

It features dual USCI modules-USCI_A0/A1 supporting enhanced UART with auto-baudrate detection and IrDA, and USCI_B0/B1 supporting synchronous SPI and I²C-with independent clock domains and configurable polarity/phase. The ADC12 module includes internal reference, sample-and-hold, and autoscan for autonomous analog acquisition without CPU intervention.

FAQ

What is the maximum operating frequency of the MSP430F247TRGCR?

The MSP430F247TRGCR supports internal DCO frequencies up to 16 MHz, with four factory-calibrated settings accurate to ±1% across voltage and temperature. External clock sources-including XT1 (32 kHz watch crystal) and XT2 (up to 16 MHz crystal or resonator)-can also drive the system clocks, enabling precise timing for communication or measurement tasks.

Does the MSP430F247TRGCR include hardware encryption acceleration?

No, the MSP430F247TRGCR does not include dedicated hardware encryption blocks such as AES or SHA accelerators. It relies on software-based cryptographic libraries executed on its 16-bit CPU. For applications requiring certified secure boot or high-throughput encryption, consider later MSP430FRxx or MSP432P4xx families with integrated crypto modules.

Can the MSP430F247TRGCR operate from a single 1.8 V supply?

Yes, the MSP430F247TRGCR is fully specified to operate across 1.8 V to 3.6 V. At 1.8 V, it maintains full functionality including 12-bit ADC operation, USCI serial communication, and timer peripherals-enabling direct interface with low-voltage sensors and energy-harvesting power supplies without regulation overhead.

How many USCI modules does the MSP430F247TRGCR support, and what protocols do they implement?

The MSP430F247TRGCR integrates four USCI modules: USCI_A0 and USCI_A1 each support UART, IrDA, and SPI; USCI_B0 and USCI_B1 each support SPI and I²C. This allows concurrent use-for example, UART to a display, I²C to a temperature sensor, SPI to an SD card, and IrDA for diagnostics-all without CPU arbitration or shared resources.

Is the MSP430F247TRGCR pin-compatible with other devices in the MSP430F24x family?

Yes, the MSP430F247TRGCR shares identical pinout and package (64-pin QFN RGC) with MSP430F248TRGCR, MSP430F249TRGCR, and their '1' variants (e.g., MSP430F2471TRGCR), enabling drop-in replacement within the same footprint. Functional differences-such as ADC12 presence or flash/RAM sizing-are handled in firmware and require no PCB changes.
