Product details
Overview
MSP430F148IPMR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 48KB flash, 2KB RAM, 12-bit ADC (8 channels), dual 16-bit timers (Timer_A3 and Timer_B7), two USARTs, and on-chip comparator-designed for battery-powered sensor systems and portable instrumentation requiring sub-µA standby current and <6 µs wake-up.
For engineers reviewing the MSP430F148IPMR datasheet, MSP430F148IPMR pinout, MSP430F148IPMR application, or MSP430F148IPMR equivalent, this page delivers verified functional specifications, package-confirmed pin roles, real-world use cases in metering and industrial sensing, and validated alternative options aligned to TI's MSP430F14x family documentation.
Technical Context
The MSP430F148IPMR implements a 16-bit CPU with constant generators and hardware multiplier, enabling high code efficiency in ultra-low-power embedded control. Its clock system integrates DCO, LFXT1 (32.768 kHz crystal), and XT2 (up to 8 MHz) oscillators, supporting five power modes including LPM3 with RAM retention at 0.1 µA.
Peripherals include a 12-bit ADC with internal reference and autoscan, two full-duplex USARTs configurable as UART or SPI, and Timer_B7 with seven capture/compare registers and shadow registers-enabling precise PWM generation, input capture, and time-critical event handling without CPU intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 125-ns instruction cycle and hardware multiplier for efficient math-intensive firmware. |
| Flash / RAM | 48KB + 256B flash memory and 2KB RAM-sufficient for complex sensor fusion algorithms and communication stacks. |
| ADC Resolution | 12-bit SAR ADC with 8 input channels, <10 µs conversion time, and built-in reference-enables precision analog monitoring without external components. |
| Power Consumption | Active mode: 280 µA at 1 MHz/2.2 V; Standby: 1.6 µA; Off mode (RAM retention): 0.1 µA-extends battery life in remote sensors. |
| Timers | Timer_A3 (3 CC registers) and Timer_B7 (7 CC registers with shadow registers)-supports simultaneous PWM, capture, and interval timing tasks. |
| Communication | Two USARTs (USART0 and USART1), each configurable as UART or SPI-enables dual-interface connectivity (e.g., RS-485 + SPI sensor bus). |
| Wake-up Time | Less than 6 µs from standby (LPM3) to active mode-critical for responsive low-duty-cycle sensing applications. |
Pinout & Package
LQFP-64 (64-pin Low-Profile Quad Flat Package), 10 mm × 10 mm body size, exposed thermal pad connected to DVSS.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DVCC (Pin 1) | Digital supply voltage (positive) | Primary digital rail; must be decoupled near pin for stable core operation at up to 8 MHz. |
| DVSS (Pin 63) | Digital ground | Reference for all digital I/O and core logic; separate from AVSS to minimize noise coupling into ADC. |
| AVCC (Pin 64) | Analog supply voltage (positive) | Supplies ADC, comparator, and analog peripherals; requires dedicated low-noise filtering. |
| AVSS (Pin 62) | Analog ground | Isolated return path for analog circuitry; must be connected to DVSS at single point only. |
| P6.0–P6.7 (Pins 59–6, 2–6) | Analog inputs A0–A7 | Eight dedicated ADC input channels; support single-ended or differential sampling with internal reference. |
| RST/NMI (Pin 58) | Reset and non-maskable interrupt | Hardware reset input; also serves as NMI source and BSL entry trigger during programming. |
| TCK/TMS/TDO/TDI (Pins 57, 56, 54, 55) | JTAG test interface | Full boundary-scan and debug capability; enables in-system programming and real-time emulation. |
| XT2IN/XT2OUT (Pins 53, 52) | High-frequency crystal oscillator | Supports external 4–8 MHz crystal for precise system clock; optional for applications needing higher timing accuracy than DCO. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-power operation | 0.1 µA off-mode current with full RAM retention enables multi-year battery life in wireless sensor nodes. |
| Dual USART with flexible mode selection | Each USART supports UART (asynchronous) and SPI (synchronous) protocols-reduces need for external level shifters or protocol bridges. |
| 12-bit ADC with integrated reference | Eliminates external voltage reference ICs and reduces BOM count while maintaining ±1 LSB INL across temperature. |
| Timer_B7 with shadow registers | Enables glitch-free PWM updates during runtime-essential for motor control and LED dimming without output interruption. |
| On-chip comparator with programmable hysteresis | Provides fast analog threshold detection (e.g., battery voltage monitoring) without ADC overhead or latency. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F149IPMR | 60KB flash, 2KB RAM, identical peripherals and pinout-direct upgrade path with increased firmware headroom. | Preferred where future firmware expansion, OTA updates, or additional security routines are required. | Select when long-term code scalability is prioritized over minimal BOM cost. |
| MSP430F147IPMR | 32KB flash, 1KB RAM, same peripheral set and 64-pin LQFP package-functionally compatible but reduced memory capacity. | Suitable for simpler sensor nodes or legacy designs where 48KB flash is unused. | Choose for cost-sensitive volume production where memory footprint remains under 30KB. |
Compared with MSP430F148IPMR, MSP430F149IPMR offers 12KB more flash for enhanced firmware resilience and feature growth, while MSP430F147IPMR trades memory capacity for lower unit cost-both retain identical timing, power, and interface behavior in shared 64-pin LQFP packaging.

FAQ
What is the maximum operating frequency of the MSP430F148IPMR?
The MSP430F148IPMR supports up to 8 MHz system clock via the XT2 oscillator (external crystal) or DCO calibration. While the CPU executes instructions at 125 ns per cycle (8 MHz), actual sustained frequency depends on supply voltage and temperature-TI specifies reliable operation up to 8 MHz at 2.2–3.6 V per SLAS272H Section 5.11.
Does the MSP430F148IPMR support in-system programming without external voltage?
Yes, the MSP430F148IPMR supports serial onboard programming (SBP) through the JTAG interface or UART-based BSL (Bootloader) without external programming voltage. The device uses internal charge pumps to generate required programming voltages-enabling field firmware updates via standard 3.3 V I/O levels.
How many ADC input channels does the MSP430F148IPMR have, and what is their resolution?
The MSP430F148IPMR integrates a 12-bit successive-approximation ADC (ADC12) with eight external input channels (A0–A7 on Port 6). It supports both single-ended and differential sampling, internal reference (2.5 V), and external reference inputs-delivering ±1 LSB integral nonlinearity across its full operating range.
Is the MSP430F148IPMR pin-compatible with other devices in the MSP430F14x family?
Yes, the MSP430F148IPMR in the 64-pin LQFP (PM) package shares identical pinout and electrical characteristics with MSP430F147IPMR and MSP430F149IPMR per TI's SLAS272H datasheet Figures 4-2 and Table 4-1-enabling drop-in replacement within the same package variant for memory-scaling design iterations.
What power-saving modes are available on the MSP430F148IPMR?
The MSP430F148IPMR provides five low-power modes (LPM0–LPM4), including LPM3 (standby) at 1.6 µA and LPM4 (off) at 0.1 µA with RAM retention. Wake-up from LPM3 to active mode occurs in less than 6 µs via external interrupt or timer event-optimized for intermittent-sensing applications.
