Product details
Overview
MSP430F248TRGCR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 48KB+256B flash, 4KB RAM, 12-bit ADC, dual USCI modules (UART/I²C/SPI), and Timer_B with seven capture/compare registers - used in battery-powered sensor nodes and portable instrumentation requiring sub-1µs wake-up and <0.1µA off-mode retention.
For engineers reviewing the MSP430F248TRGCR datasheet, MSP430F248TRGCR pinout, MSP430F248TRGCR application, or MSP430F248TRGCR equivalent, key selection criteria include ADC12 channel count, QFN-64 package thermal performance, USCI_A1/USCI_B1 interface availability, and SVSIN/SVSOUT supervision capability for industrial-grade voltage monitoring.
Technical Context
The MSP430F248TRGCR implements a calibrated DCO with four factory-trimmed frequencies (±1%), supports dual crystal oscillators (XT1 for 32kHz watch crystal, XT2 for up to 16MHz), and integrates a hardware multiplier for efficient signal processing. Its basic clock module enables dynamic switching between ACLK, SMCLK, and MCLK sources without software intervention.
It features two independent universal serial communication interfaces: USCI_A0/A1 support UART with auto-baud detection and IrDA, while USCI_B0/B1 support synchronous SPI and I²C master/slave modes. The ADC12 module includes internal reference, sample-and-hold, and autoscan - all configurable via register writes without CPU intervention.
Key Specifications

|---|---|
| Core Architecture | 16-bit RISC CPU with 62.5-ns instruction cycle; enables deterministic real-time control in low-clock-rate applications. |
| Flash / RAM | 48KB+256B flash memory with security fuse; 4KB RAM - sufficient for firmware + sensor buffer + communication stack in compact edge devices. |
| ADC Resolution | 12-bit SAR ADC with 8 input channels, internal reference, and autoscan - supports simultaneous multi-sensor acquisition without CPU polling. |
| Low-Power Modes | Five power modes including Off mode (0.1 µA RAM retention) and Standby (0.3 µA VLO); critical for >10-year battery life in remote sensors. |
| Timer Resources | Timer_A with three capture/compare registers; Timer_B with seven capture/compare registers and shadow registers - enables precise PWM generation and time-stamped event capture. |
| Communication Peripherals | Four USCI modules: USCI_A0/A1 (UART/IrDA/SPI), USCI_B0/B1 (SPI/I²C) - supports dual concurrent protocols (e.g., I²C sensor bus + UART telemetry). |

| P6.7/A7/SVSIN | Analog input / SVS monitor input | Accepts external voltage for supervised monitoring (e.g., battery pack voltage) and routes same signal to ADC for digitized logging. |
| RST/NMI | Reset / non-maskable interrupt | Performs cold reset on power-up and delivers high-priority fault interrupts (e.g., watchdog timeout or SVS trip) with guaranteed latency. |
Key Features
| Feature | Design Value |
