Product details
Overview
MSP430F248TPM from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 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 plus shadow registers), four USCI modules (dual UART/IrDA/SPI and dual I²C/SPI), and on-chip comparator - deployed in battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the MSP430F248TPM datasheet, MSP430F248TPM pinout, MSP430F248TPM application, or MSP430F248TPM equivalent, key selection criteria include its 64-pin QFP package, -40°C to 105°C industrial temperature range, ADC12 resolution and sampling rate, USCI_A1/USCI_B1 interface availability, and SVS/SVM supply monitoring capability.
Technical Context
The MSP430F248TPM implements a 16-bit CPU with constant generators and hardware multiplier for optimized code efficiency. Its basic clock system integrates a calibrated DCO (±1% accuracy at 1–16 MHz), LF oscillator, and support for external crystals (XT1: 32 kHz, XT2: up to 16 MHz).
It features five low-power modes (LPM0–LPM4) enabling sub-µA standby current (0.3 µA in VLO mode) and ultra-fast wake-up (<1 µs). The ADC12 module supports internal reference, sample-and-hold, and autoscan - directly feeding data to RAM or peripherals via DMA-capable USCI interfaces.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F249TPM | 60KB+256B flash, 2KB RAM; identical peripherals and pinout | Higher flash capacity supports larger protocol stacks (e.g., full Zigbee HA) but less RAM for data buffering | Select when firmware size exceeds 48KB and RAM usage remains ≤2KB |
