Texas Instruments MSP430F248TRGCT

Overview

MSP430F248TRGCT from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 48KB+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 (dual UART/IrDA/SPI + dual SPI/I²C), and operation across 1.8 V–3.6 V. It targets battery-powered sensor nodes and portable instrumentation requiring fast wake-up (<1 µs) and precise analog measurement.

For engineers reviewing the MSP430F248TRGCT datasheet, MSP430F248TRGCT pinout, MSP430F248TRGCT application, or MSP430F248TRGCT equivalent, key selection criteria include ADC12 resolution and channel count, Timer_B shadow register support for glitch-free PWM, USCI_A1/USCI_B1 availability for dual-protocol communication, and QFN-64 (RGC) package thermal performance in space-constrained designs.

Technical Context

The MSP430F248TRGCT implements a calibrated DCO with four factory-trimmed frequencies (±1%), supports dual crystal oscillators (XT1 for LF, XT2 for HF), and integrates SVS/SVM circuitry with programmable threshold detection. Its ADC12 module includes internal reference, sample-and-hold, and autoscan-enabling autonomous multi-channel conversion sequences without CPU intervention.

Timer_B features seven capture/compare registers with independent shadow registers per channel, allowing synchronized update of PWM duty cycles across multiple outputs. The four USCI modules provide hardware-configurable UART (with auto-baud), IrDA, SPI, and I²C-each supporting independent clock sources and asynchronous operation.

FAQ

What is the maximum operating frequency of the MSP430F248TRGCT?

The MSP430F248TRGCT supports internal DCO frequencies up to 16 MHz, with four factory-calibrated settings accurate to ±1% across voltage and temperature. External crystal oscillators (XT1 and XT2) can also drive the system clock, enabling precise timing for communication protocols or high-resolution ADC sampling without DCO drift.

Does the MSP430F248TRGCT include a hardware multiplier?

Yes, the MSP430F248TRGCT integrates a 16-bit hardware multiplier (MPY, MPYS, MAC, MACS) that executes multiply-accumulate operations in a single cycle. This accelerates fixed-point math used in digital filtering, PID control, and sensor linearization-reducing CPU load and improving real-time response in the MSP430F248TRGCT.

Can the MSP430F248TRGCT operate from a single 1.8-V supply?

Yes, the MSP430F248TRGCT 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 communication, and Timer_B shadow register updates-with active current consumption scaling proportionally, making it ideal for single-cell lithium primary battery applications.

How many analog input channels does the ADC12 module support on the MSP430F248TRGCT?

The ADC12 module on the MSP430F248TRGCT supports eight analog input channels (A0–A7), accessible via P6.0 through P6.7. All channels share the same 12-bit resolution and internal reference, and autoscan mode allows sequential conversion without software intervention-enabling efficient multi-sensor data acquisition in the MSP430F248TRGCT.

Is the MSP430F248TRGCT pin-compatible with other devices in the MSP430F24x family?

Yes, the MSP430F248TRGCT shares identical pinout and package (64-pin QFN RGC) with MSP430F247, MSP430F249, MSP430F2481, and MSP430F2491. This allows direct PCB reuse across variants-e.g., upgrading flash size or removing ADC-without layout changes, provided peripheral usage aligns with the target device's integrated modules.
