Product details
Overview
MSP430F247TRGCT 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 + shadow registers), four USCI modules (dual UART/IrDA/SPI and dual I²C/SPI), 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 MSP430F247TRGCT datasheet, MSP430F247TRGCT pinout, MSP430F247TRGCT application, or MSP430F247TRGCT equivalent, key selection criteria include its 64-pin QFN (RGC) package, ADC12 resolution and channel count, Timer_B shadow register support for glitch-free PWM, dual USCI_A/B flexibility for mixed-protocol systems, and verified ultra-low standby current (0.3 µA).
Technical Context
The MSP430F247TRGCT implements a calibrated DCO enabling sub-1 µs wake-up from standby mode, paired with five low-power modes optimized for extended battery life in measurement applications. Its architecture integrates constant generators and 16-bit registers for high code efficiency in embedded control tasks.
It supports dual crystal oscillators (XT1 for 32 kHz watch crystal, XT2 for up to 16 MHz), internal reference voltage generation (VREF+/VREF−), and SVS/SVM circuitry for supply monitoring. The ADC12 module includes sample-and-hold and autoscan-critical for multi-channel sensor acquisition without CPU intervention.

FAQ
What is the maximum operating frequency of the MSP430F247TRGCT?
The MSP430F247TRGCT supports a maximum system clock frequency of 16 MHz using the XT2 oscillator with an external crystal or resonator. Its calibrated DCO also provides internal frequencies up to 16 MHz with ±1% accuracy across voltage and temperature, eliminating the need for external high-frequency crystals in many applications. This enables high-speed ADC sampling and responsive real-time control within the MSP430F247TRGCT's ultra-low-power envelope.
Does the MSP430F247TRGCT include hardware encryption or secure boot features?
No, the MSP430F247TRGCT does not integrate hardware encryption accelerators or secure boot functionality. It relies on software-based security measures and the optional BSL password lock for basic code protection. For applications requiring cryptographic operations or tamper-resistant boot, designers should consider newer MSP430FRxx or MSP432P4xx families. The MSP430F247TRGCT prioritizes ultra-low power and analog integration over security peripherals.
Can the MSP430F247TRGCT drive an LCD directly?
No, the MSP430F247TRGCT does not include an integrated LCD controller or segment drivers. Unlike certain MSP430 variants (e.g., MSP430F4xx or MSP430FR6xx), it lacks dedicated LCD pins and bias generation circuitry. To interface with segment-based LCDs, external driver ICs or GPIO-based static/dynamic driving (with external bias resistors) are required. This omission reflects the MSP430F247TRGCT's focus on general-purpose sensing and communication rather than human-interface display functions.
What development tools are officially supported for the MSP430F247TRGCT?
Texas Instruments officially supports the MSP430F247TRGCT with the MSP-FET430UIF (USB JTAG emulator), MSP-TS430RGC64 target socket board, and Code Composer Studio v6+ IDE. The device is also compatible with Energia and naken_asm toolchains. TI's MSP430Ware peripheral driver library provides tested initialization routines for ADC12, USCI, and Timer_B-ensuring rapid bring-up of the MSP430F247TRGCT in production firmware.
Is the MSP430F247TRGCT qualified for automotive applications?
No, the MSP430F247TRGCT is not AEC-Q100 qualified and is specified for industrial temperature range (–40°C to 105°C), not automotive grade. While its operating temperature range overlaps with some automotive cabin applications, it lacks automotive-specific qualification, failure-in-time (FIT) data, and enhanced ESD/EMC robustness required for under-hood or safety-critical systems. For automotive use, TI recommends the MSP430FR59xx or MSP430i2xxx families with formal AEC-Q100 certification.
