Product details
Overview
MSP430F249TRGCR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 60KB+256B flash memory, 2KB 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 plus shadow registers), four USCI modules (dual UART/IrDA/SPI + dual SPI/I²C), and integrated comparator. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the MSP430F249TRGCR datasheet, MSP430F249TRGCR pinout, MSP430F249TRGCR application, or MSP430F249TRGCR 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 MSP430F249TRGCR 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 includes constant generators and 16-bit registers for high code efficiency.
It integrates two independent USCI modules per interface type (USCI_A0/A1 for UART/IrDA/SPI; USCI_B0/B1 for SPI/I²C), supporting simultaneous asynchronous and synchronous communication. The ADC12 module features internal reference, sample-and-hold, and autoscan-enabling autonomous multi-channel acquisition without CPU intervention.
Key Specifications

Pinout & Package
Package: 64-pin QFN (RGC), 9 mm × 9 mm, 0.5 mm pitch, thermal pad on underside connected to DVSS.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DVCC (Pin 1) | Digital power supply | Primary 1.8–3.6 V supply for CPU, timers, USCI, and GPIO logic; requires local 100 nF decoupling. |
| AVCC (Pin 64) | Analog power supply | Isolated 1.8–3.6 V supply dedicated to ADC12 and comparator; must be filtered separately from DVCC. |

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, no thermal pad. | Preferred for prototyping or through-hole assembly; less suitable for space-constrained PCBs. | Select MSP430F249TPM when board layout accommodates QFP or requires easier hand-soldering and rework. |
| MSP430F248TRGC | 48KB+256B flash, 4KB RAM; lacks Timer_B shadow registers and one USCI_A module. | Suitable for simpler protocols (e.g., UART-only comms) and smaller firmware footprints. | Choose MSP430F248TRGC when application does not require dual UART/IrDA or glitch-free multi-output PWM. |
Compared with MSP430F249TPM and MSP430F248TRGC, the MSP430F249TRGCR uniquely balances high flash capacity, full Timer_B shadow functionality, and compact QFN packaging-making it optimal for production-ready, space- and power-constrained embedded systems requiring robust mixed-signal control.

FAQ
What is the maximum operating frequency of the MSP430F249TRGCR?
The MSP430F249TRGCR supports internal DCO frequencies up to 16 MHz with four factory-calibrated settings accurate to ±1%, and external clock sources via XT2 (up to 16 MHz) or XT1 (32 kHz). This enables high-speed signal processing while retaining ultra-low-power operation in active mode (270 µA at 1 MHz, 2.2 V).
Does the MSP430F249TRGCR include a hardware multiplier?
Yes, the MSP430F249TRGCR integrates a 16-bit hardware multiplier supporting MPY, MPYS, MAC, and MACS instructions. This accelerates fixed-point arithmetic for applications such as digital filtering, motor control, and sensor linearization-reducing CPU load and active time.
Can the MSP430F249TRGCR operate from a single 2.0 V battery?
Yes, the MSP430F249TRGCR operates across 1.8 V to 3.6 V, making it fully functional at 2.0 V. At this voltage, typical active current is ~300 µA at 1 MHz, and standby current remains 0.3 µA-ideal for coin-cell or single Li-ion battery systems.
How many USCI modules does the MSP430F249TRGCR support?
The MSP430F249TRGCR supports four 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 use of multiple serial protocols-for example, UART for debug, I²C for sensors, and SPI for displays or transceivers.
Is the MSP430F249TRGCR pin-compatible with other MSP430F24x devices?
Yes, the MSP430F249TRGCR shares identical pinout and package (64-pin RGC) with all MSP430F24x and MSP430F24x1 variants-including MSP430F247TRGC, MSP430F248TRGC, and MSP430F2491TRGC-ensuring hardware compatibility across firmware variants and feature subsets.
