MSP430F248TPM - 16MHz 48KB MCU 12-bit ADC | Texas Instruments
料号： MSP430F248TPM ✓ 量产中MSP430F248TPM 概述
A mixed-signal microcontroller combines a general-purpose CPU with analog measurement and communication peripherals. The MSP430 belongs to the RISC MCU -> low-power microcontroller -> embedded semiconductor hierarchy, targeting portable, industrial, and instrumented systems that need deterministic control, low standby current, and fast wake-up.
The verified device features include a 16 MHz maximum CPU frequency, 16-bit RISC architecture, 48 KB Flash plus 256 bytes, 4 KB SRAM, 12-bit ADC, comparator, two USCI peripherals supporting I2C, SPI, and UART, and a hardware multiplier. The supply-voltage range shown in the verified datasheet references is 1.8 V to 3.6 V.
Its low-power operating modes are central to the design: the verified data cites 270 µA active current at 1 MHz and 2.2 V, 0.3 µA standby current using VLO, 0.1 µA off current with RAM retention, and standby wake-up in less than 1 µs. These figures make the device suitable for duty-cycled sensing systems where average energy matters more than uninterrupted processing.
Typical uses include low-power sensor acquisition, battery-operated instrumentation, industrial control, communications bridges, and embedded measurement nodes. The ADC and comparator support analog front-end conditioning, while the USCI interfaces connect displays, sensors, transceivers, and external data storage.
Designers should select decoupling, clock, and peripheral connections according to the manufacturer datasheet and verify all unused pins. Because the verified source identifies a 64-pin LQFP, PCB design should use a 64-pin-compatible footprint and preserve the exposed thermal behavior and recommended layout.
This page combines the verified manufacturer and distributor references with practical selection guidance, application context, and explicit data gaps where the supplied sources do not provide a complete value.

典型应用
MSP430F248TPM 适用于 7 应用s: Battery-Powered Sensor Acquisition, Industrial Measurement Node, Low-Power Communications Bridge, Battery-Operated Field Instrument, Embedded Data Logger, Smart Sensor Interface, Portable Medical or Wellness Monitor.
Battery-Powered Sensor Acquisition
The MSP430F248TPM fits low-power sensor acquisition because its verified 270 µA active current at 1 MHz and 2.2 V can be duty-cycled around short measurement windows. The 12-bit ADC provides a direct conversion resource, while the comparator can support threshold or alarm decisions without continuous software polling. Use standby VLO at 0.3 µA and off mode with RAM retention at 0.1 µA only when the complete system power budget supports those states. Design the sensor, regulator, and wake interval together.
推荐
Industrial Measurement Node
For industrial measurement, the MSP430F248TPM combines a 16 MHz 16-bit CPU, 4 KB SRAM, 12-bit ADC, and comparator in one 64-pin LQFP device. It can digitize analog process signals, compare thresholds, and communicate results through I2C, SPI, or UART. The -40 °C to +105 °C operating range supports industrial temperature requirements stated by the verified product listing, although the final design still requires transient, grounding, and calibration validation.
推荐
Low-Power Communications Bridge
The MSP430F248TPM is suitable for a communications bridge when a small controller must manage sensors, memory, and a serial link without continuous high-power operation. Two USCI peripherals support I2C, SPI, and UART, allowing local sensor polling and host connectivity. The 16 MHz CPU provides timing headroom, while less-than-1-µs standby wake-up helps reduce response latency. Validate protocol timing and bus levels against the selected external transceiver.
推荐
Battery-Operated Field Instrument
The MSP430F248TPM can serve as the control core of a field instrument that alternates between measurement and sleep. Its 48 KB Flash supports embedded firmware and calibration data, while 4 KB SRAM supports short acquisition and processing routines. The 12-bit ADC and comparator handle analog conditioning, and the fast wake-up helps the instrument respond promptly after a scheduled event. Specify regulator quiescent current and sensor standby behavior to obtain a realistic field-runtime estimate.
推荐
Embedded Data Logger
For embedded logging, the MSP430F248TPM can periodically sample analog inputs and store or forward measurements through its USCI interfaces. Its 16-bit RISC processor supports deterministic control tasks, while the hardware multiplier and 4 KB SRAM help manage formatting and buffer operations. Use the low-power modes between records rather than keeping the CPU active continuously. External nonvolatile storage, write endurance, timestamp accuracy, and bus integrity should be validated in the complete system.
推荐
Smart Sensor Interface
The MSP430F248TPM works well as a smart sensor interface when a local microcontroller must convert analog signals, apply thresholds, and expose data over a serial bus. Its 12-bit ADC and comparator support measurement and event detection, while I2C and SPI simplify connection to sensors and memory. Keep analog traces compact, provide a stable reference, and verify the final pin multiplexing in the 64-pin LQFP pin table. The MCU’s low-power characteristics can reduce maintenance burden in remote installations.
推荐
Portable Medical or Wellness Monitor
The MSP430F248TPM can support portable sensing platforms where battery efficiency and mixed-signal integration are important. The 12-bit ADC can acquire low-bandwidth physiological or environmental signals, while the comparator can establish simple thresholds. The device’s low standby and off currents can reduce energy use between measurements, but medical-system suitability depends on validation of accuracy, isolation, safety, and applicable regulatory requirements. Do not infer medical certification from the MCU specifications alone.

设计说明
Use the MSP430F248TPM's low-power modes as part of the system architecture rather than treating the MCU current figures as a complete power budget. The verified values are 270 µA active at 1 MHz and 2.2 V, 0.3 µA standby in VLO, and 0.1 µA off with RAM retention. Include the sensor, regulator, pull resistors, communications transceiver, and leakage paths in the calculation. Confirm wake-up behavior and required GPIO states against the manufacturer guidance.
Route the 64-pin LQFP footprint using the official Texas Instruments package drawing and keep analog input paths away from fast-switching digital traces. Place local decoupling at the supply pins, provide a stable analog reference where required, and follow the datasheet’s exposed-pad and thermal recommendations. Because the verified source confirms a 10 mm × 10 mm LQFP but does not provide complete pin-level routing data, validate the PCB against the current manufacturer drawings before fabrication.
The 12-bit ADC and comparator should be placed in an analog layout that minimizes digital coupling and ground bounce. Keep sensor traces short, use a quiet reference node, and separate analog and return-current paths as far as practical. The MSP430F248TPM supports I2C, SPI, and UART, but each interface requires correct signal levels, pull-up or termination choices, and firmware timing based on the selected bus and peripheral configuration.
合规信息
The supplied verified sources do not state compliance values for this exact MPN. Compliance must be confirmed from the current Texas Instruments product documentation and applicable supplier declarations.
