Product details
Overview
MSP430F148IPM from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 48KB flash, 2KB RAM, a 12-bit ADC with 8 analog inputs, dual 16-bit timers (Timer_A3 and Timer_B7), two USARTs supporting UART/SPI, and on-chip comparator. It operates from 1.8 V to 3.6 V and targets battery-powered sensor systems and portable instrumentation.
For engineers reviewing the MSP430F148IPM datasheet, MSP430F148IPM pinout, MSP430F148IPM application, or MSP430F148IPM equivalent, this page delivers verified specifications, functional pin mapping, real-world use cases, and validated alternative options for embedded design and long-life industrial deployment.
Technical Context
The MSP430F148IPM implements a 16-bit CPU with constant generators and hardware multiplier, enabling high code efficiency in ultra-low-power operation. Its five power-saving modes-including LPM3 with sub-µA standby current-support rapid wake-up (<6 µs) and extended battery life in measurement applications.
It integrates dual synchronous serial interfaces (USART0/USART1), a 12-bit ADC with internal reference and autoscan, and full JTAG debugging. The device uses a digitally controlled oscillator (DCO) with external resistor tuning (ROSC pin) and supports both LFXT1 (watch crystal) and XT2 (high-frequency crystal) oscillators.

FAQ
What is the maximum operating frequency of the MSP430F148IPM?
The MSP430F148IPM does not have a fixed maximum clock frequency specification; its digitally controlled oscillator (DCO) is calibrated to operate up to approximately 8 MHz using the XT2 oscillator or internal DCO tuning. Actual system clock (MCLK) depends on selected source and divider settings, with typical configurations reaching 7.8 MHz under recommended conditions.
Does the MSP430F148IPM support in-system programming without external high voltage?
Yes, the MSP430F148IPM supports serial onboard programming via its built-in bootloader (BSL) using only the standard supply voltage (1.8–3.6 V). No external programming voltage is required, and programming can be performed through UART or SPI using the existing USART interfaces - simplifying field firmware updates.
How many analog input channels does the MSP430F148IPM ADC support?
The MSP430F148IPM features a 12-bit ADC12 module with eight selectable analog input channels (A0–A7), mapped directly to P6.0 through P6.7. These inputs support both internal reference (2.5 V) and external reference (VeREF+) configurations, with sample-and-hold and autoscan functionality enabled in firmware.
Is the MSP430F148IPM pin-compatible with other devices in the MSP430F14x family?
Yes, the MSP430F148IPM in the LQFP-64 (PM) package shares identical pinout and electrical characteristics with MSP430F147IPM and MSP430F149IPM. This allows direct PCB-level substitution within the same package variant, provided flash/RAM requirements align with target firmware size and runtime needs.
What low-power modes are available on the MSP430F148IPM, and what is the lowest current draw?
The MSP430F148IPM offers five power modes: AM (active), LPM0–LPM3, and LPM4. In LPM3 (real-time clock active, CPU/MCLK off), it draws just 1.6 µA at 2.2 V. In LPM4 (all clocks off, RAM retention), current drops to 0.1 µA - enabling multi-year operation on small batteries when paired with infrequent wake-up events.
