Product details
Overview
MSP430F148IPMG4 from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 48KB flash, 2KB RAM, 12-bit ADC (8-channel), dual 16-bit timers (Timer_A3 and Timer_B7), two USARTs, and on-chip comparator - designed for battery-powered sensor systems and portable measurement devices operating from 1.8 V to 3.6 V.
For engineers reviewing the MSP430F148IPMG4 datasheet, MSP430F148IPMG4 pinout, MSP430F148IPMG4 application, or MSP430F148IPMG4 equivalent, key selection criteria include active-mode current (280 µA @ 1 MHz), wake-up time (<6 µs from standby), ADC conversion time (<10 µs), JTAG debug support, and LQFP-64 package compatibility with industrial-grade temperature range.
Technical Context
The MSP430F148IPMG4 implements a 16-bit CPU with constant generators and hardware multiplier, enabling high code efficiency in ultra-low-power embedded control. Its five power-saving modes-including RAM-retention off mode (0.1 µA) and fast wake-up-target extended battery life in portable instrumentation.
It integrates dual synchronous serial interfaces (USART0/USART1) supporting UART and SPI protocols, a 12-bit ADC with internal reference and autoscan, and Timer_B7 with seven capture/compare registers and shadow registers for precise PWM and timing control in real-time sensor acquisition.
