Product details
Overview
MSP430F249TRGCT from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 60KB+256B flash memory, 2KB RAM, a 12-bit ADC with 8 channels, dual 16-bit timers (Timer_A3 and Timer_B7), four USCI modules (two UART/IrDA/SPI and two 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 MSP430F249TRGCT datasheet, MSP430F249TRGCT pinout, MSP430F249TRGCT application, or MSP430F249TRGCT equivalent, key selection considerations include its 64-pin QFN (RGC) package, ADC12 resolution and sampling rate, USCI_A1/USCI_B1 interface availability, SVS/SVM supply monitoring, and calibrated DCO enabling sub-1-µs wake-up from standby mode.
Technical Context
The MSP430F249TRGCT implements a 16-bit CPU with constant generators and hardware multiplier (MPY/MPYS/MAC/MACS), supporting five low-power modes optimized for extended battery life. Its basic clock system integrates DCO (calibrated to ±1% at 1 MHz, 8 MHz, 12 MHz, 16 MHz), LFXT1 (32-kHz crystal), and XT2 (up to 16 MHz crystal/resonator).
It features two independent USCI modules per A/B type: USCI_A0/A1 support enhanced UART with auto-baud detection and IrDA encoding/decoding; USCI_B0/B1 support synchronous SPI and I²C master/slave operation. The ADC12 module includes internal reference, sample-and-hold, and autoscan-enabled only in MSP430F24x (not F24x1) variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 62.5-ns instruction cycle; enables efficient C code execution and deterministic real-time response. |
| Flash / RAM | 60KB+256B flash memory with security fuse; 2KB RAM-supports complex firmware with data logging and communication stacks. |
| ADC Resolution | 12-bit SAR ADC with 8 input channels, internal reference, and autoscan-enables simultaneous multi-sensor analog acquisition. |
| Timers | Timer_A3 (3 capture/compare registers) + Timer_B7 (7 capture/compare registers with shadow registers)-supports PWM generation, input capture, and precise timebase management. |
| USCI Modules | Four USCI peripherals: USCI_A0/A1 (UART/IrDA/SPI), USCI_B0/B1 (SPI/I²C)-allows concurrent serial protocols for sensor fusion and host connectivity. |
| Supply Range | 1.8 V to 3.6 V operation-compatible with single-cell Li-ion, Li-polymer, or dual AA/AAA battery systems without regulation overhead. |
| Low-Power Modes | Active (270 µA @ 1 MHz, 2.2 V), Standby (0.3 µA), Off with RAM retention (0.1 µA)-extends operational life in intermittent-sensing applications. |
Pinout & Package
Package: 64-pin QFN (RGC), 9 mm × 9 mm, 0.5 mm pitch, exposed thermal pad (to be connected to DVSS).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DVCC (Pin 1) | Digital power supply | Primary 1.8–3.6 V digital rail; requires local decoupling near pin for noise-sensitive MCU operation. |
| AVCC (Pin 64) | Analog power supply | Isolated 1.8–3.6 V rail dedicated to ADC12 and comparator; must be filtered separately from DVCC. |
| P6.0–P6.7/A0–A7 (Pins 59,60,61,2,3,4,5,6) | Analog inputs | Eight dedicated ADC12 input channels; P6.7 also serves as SVS input for supply voltage supervision. |
| USCI_A1TXD/USCI_A1RXD (Pins 34,35) | UART channel 2 I/O | Full-duplex asynchronous serial interface supporting auto-baud detection-ideal for host MCU or PC communication. |
| USCI_B1SIMO/USCI_B1SOMI (Pins 45,46) | I²C/SPI data I/O | Configurable as I²C SDA/SCL or SPI MOSI/MISO-enables direct connection to digital sensors (e.g., temperature, humidity). |
| RST/NMI (Pin 58) | Reset & NMI input | Combines power-on reset, brownout detection, and non-maskable interrupt-critical for fail-safe system recovery. |
Key Features
| Feature | Design Value |
|---|---|
| Calibrated DCO oscillator | Four factory-trimmed frequencies (1/8/12/16 MHz) with ±1% accuracy-eliminates need for external crystal in cost-sensitive timing applications. |
| Ultra-fast wake-up | Less than 1 µs from standby mode to active execution-preserves energy in duty-cycled sensing while maintaining responsiveness. |
| Supply voltage supervisor | Programmable SVS threshold with SVSOUT output (Pin P5.7)-enables autonomous brownout response without CPU intervention. |
| Bootstrap loader (BSL) | On-chip UART-based firmware update via P1.1/P1.2-allows field reprogramming without JTAG hardware. |
| Hardware multiplier | MPY/MPYS/MAC/MACS instructions execute in one cycle-accelerates filtering, FFT, and control loop math in sensor signal processing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F249TPM | Identical core specs but in 64-pin QFP (PM) package; larger footprint, through-hole compatible. | Preferred where manual assembly, prototyping, or legacy board compatibility is required. | Select MSP430F249TPM for through-hole evaluation or when QFP layout constraints dominate over size/power. |
| MSP430F248TRGCT | 48KB+256B flash, 4KB RAM; lacks USCI_A1 and USCI_B1 modules present in MSP430F249TRGCT. | Suitable for simpler communication needs (single UART + single I²C) and lower firmware complexity. | Choose MSP430F248TRGCT when dual USCI pairs are unnecessary and higher RAM is prioritized over peripheral count. |
Compared with MSP430F249TPM and MSP430F248TRGCT, the MSP430F249TRGCT uniquely balances high flash capacity (60 KB), full peripheral set (dual USCI_A/B), and compact QFN packaging-making it optimal for space-constrained, feature-rich embedded designs requiring field firmware updates and multi-protocol connectivity.

FAQ
What is the maximum operating frequency of the MSP430F249TRGCT?
The MSP430F249TRGCT supports a maximum system clock (MCLK) frequency of 16 MHz, achievable using the internal calibrated DCO (±1% accuracy at 16 MHz), external XT2 crystal/resonator, or external digital clock source. This enables high-speed instruction execution while maintaining ultra-low-power operation in active mode.
Does the MSP430F249TRGCT include an integrated ADC?
Yes, the MSP430F249TRGCT includes a 12-bit successive approximation register (SAR) ADC (ADC12 module) with eight input channels (A0–A7), internal reference voltage generator, sample-and-hold circuitry, and autoscan functionality-fully functional as confirmed in the MSP430F24x series documentation.
What package type is used for the MSP430F249TRGCT?
The MSP430F249TRGCT uses a 64-pin QFN package (RGC), measuring 9 mm × 9 mm with 0.5 mm pitch and an exposed thermal pad. The pad must be soldered to a DVSS-connected copper area to ensure proper thermal dissipation and electrical stability.
Can the MSP430F249TRGCT be programmed without a JTAG debugger?
Yes, the MSP430F249TRGCT includes a UART-based bootstrap loader (BSL) accessible via pins P1.1 (RXD) and P1.2 (TXD). This allows firmware programming and updates using only a UART interface and no external JTAG hardware-ideal for production line flashing or field upgrades.
How many USCI modules does the MSP430F249TRGCT support?
The MSP430F249TRGCT supports four universal serial communication interface (USCI) modules: 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 multi-protocol communication without resource contention.
