Texas Instruments MSP430F248TPMR

Overview

MSP430F248TPMR 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 and dual I²C/SPI), and on-chip comparator. It operates across 1.8 V to 3.6 V and targets battery-powered sensor nodes and portable instrumentation.

For engineers reviewing the MSP430F248TPMR datasheet, MSP430F248TPMR pinout, MSP430F248TPMR application, or MSP430F248TPMR equivalent, key selection criteria include its 48KB flash capacity, full ADC12 implementation, 64-pin QFP package with 48 I/O pins, integrated SVS/SVM, and support for dual USCI_A/USCI_B peripherals in low-power embedded control.

Technical Context

The MSP430F248TPMR implements a 16-bit CPUX architecture with constant generators and hardware multiplier (MPY/MPYS/MAC/MACS), enabling high code efficiency in ultra-low-power operation. Its basic clock system integrates DCO with four factory-calibrated frequencies (±1%), XT1 (32 kHz crystal), and XT2 (up to 16 MHz crystal/resonator), supporting flexible clock routing to MCLK, SMCLK, and ACLK.

It features dual USCI modules: USCI_A0/A1 each support enhanced UART (auto-baud detect, IrDA), SPI, and LIN; USCI_B0/B1 each support I²C and SPI. The ADC12 module includes internal reference, sample-and-hold, autoscan, and conversion clock input (ADC12CLK) for precise timing control.

FAQ

What is the maximum operating frequency of the MSP430F248TPMR?

The MSP430F248TPMR supports internal DCO frequencies up to 16 MHz and external crystal oscillator inputs (XT2) up to 16 MHz. Its 16-bit RISC core executes instructions at 62.5 ns per cycle at 16 MHz, enabling real-time response in time-critical sensor fusion tasks. The calibrated DCO eliminates need for external clock source in many applications.

Does the MSP430F248TPMR include a hardware multiplier?

Yes, the MSP430F248TPMR includes a dedicated hardware multiplier supporting MPY, MPYS, MAC, and MACS instructions. This unit accelerates fixed-point math operations such as FIR filtering, PID control, and sensor linearization - reducing CPU cycles by up to 10× versus software emulation and improving deterministic timing in closed-loop systems.

Can the MSP430F248TPMR operate from a single 2.0 V supply?

Yes, the MSP430F248TPMR is fully specified for operation from 1.8 V to 3.6 V. At 2.0 V, all peripherals-including ADC12, USCI modules, and timers-function within datasheet limits. Its brownout detector (BOR) and supply voltage supervisor (SVS) remain active down to 1.7 V, ensuring reliable reset behavior during battery discharge.

How many I²C interfaces does the MSP430F248TPMR support?

The MSP430F248TPMR supports two independent I²C interfaces via USCI_B0 and USCI_B1. Each operates as master or slave, with programmable clock speed (up to 400 kHz standard mode), automatic clock stretching, and 7-bit/10-bit addressing - enabling concurrent communication with multiple sensors (e.g., temperature, humidity, pressure) on separate I²C buses.

Is the MSP430F248TPMR pin-compatible with other MSP430F2xx devices?

The MSP430F248TPMR shares the same 64-pin QFP (PM) package and pinout with MSP430F247TPMR, MSP430F249TPMR, and MSP430F2410TPMR. However, functional differences exist - e.g., MSP430F2410TPMR has 56KB flash and no USCI_B1 - so firmware and peripheral initialization must be validated per device. Pin compatibility simplifies PCB reuse across this family.
