MSP430F235TPM - 16MHz Mixed-Signal MCU | Texas Instruments
部品番号: MSP430F235TPM ✓ 生産中MSP430F235TPM 概要
A mixed-signal microcontroller combines a digital processor with analog conversion and conditioning functions on one device. The MSP430 architecture belongs to the microcontroller, embedded processor, and power-management IC hierarchy, integrating real-time control, communications, and analog measurement while reducing the number of discrete components required in an embedded system.
The MSP430F235TPM operates at up to 16 MHz and provides 16 KB of Flash for program storage plus 512 bytes of SRAM for working memory. Its integrated 10-bit ADC and two operational amplifiers support mixed-signal designs that need to acquire, condition, and process sensor data. Peripheral support includes I2C, SPI, and UART interfaces for connecting displays, sensors, transceivers, and external data-acquisition equipment.
The device includes five power-saving modes and can wake from standby in less than 6 microseconds, according to the supplied Texas Instruments documentation. This combination of rapid wake-up and low-power operation supports systems that spend most of their time inactive but must respond quickly to external events. Its FLL+ frequency-locked loop provides clocking support for mixed-signal embedded systems.
Typical uses include industrial sensor nodes, compact data-acquisition systems, low-power instrumentation, and communication-connected embedded controls. The I2C and SPI interfaces support short-distance peripheral connections, while UART provides a straightforward serial path for configuration, logging, or supervisory communication. The integrated ADC and amplifiers are particularly relevant to designs in which analog conditioning must coexist with digital control.
When planning the PCB, use the 64-LQFP footprint and follow the manufacturer pin and layout guidance before assigning analog, digital, power, and ground pins. Account for ADC noise, analog grounding, supply decoupling, clock stability, and programming access. Confirm the exact peripheral configuration and pin multiplexing in the manufacturer datasheet because the supplied search results summarize the device but do not expose the complete pin table.
This product record combines verified manufacturer and distributor information with procurement data, package details, application guidance, and same-family replacement candidates. It provides a practical engineering summary for engineers evaluating the MSP430F235TPM for low-power mixed-signal embedded designs, while clearly identifying detailed parameters that require confirmation in the full manufacturer datasheet.

主な用途
MSP430F235TPM の用途: 6 件s: Industrial Sensor Node, Compact Data-Acquisition System, Low-Power Environmental Monitor, Battery-Powered Instrumentation, Communications-Assisted Embedded Control, Precision Control and Monitoring.
Industrial Sensor Node
The MSP430F235TPM suits an industrial sensor node that must acquire an analog signal, process it digitally, and communicate through a serial interface. Its 10-bit ADC and two integrated operational amplifiers can form the foundation of a compact measurement channel, while I2C, SPI, and UART provide options for sensors, local storage, and supervisory controllers. Five power-saving modes, 0.1 uA off-mode current with RAM retention, and standby wake-up in less than 6 microseconds support designs that remain active mainly around scheduled measurements. The 16 MHz RISC core provides a 125 ns instruction cycle for responsive control. Designers should still verify ADC accuracy, analog input limits, and peripheral multiplexing in the manufacturer datasheet.
おすすめ
Compact Data-Acquisition System
The MSP430F235TPM can serve as the control device in a compact data-acquisition system where sensor conditioning, conversion, and digital processing must share a limited board area. The 10-bit ADC and two on-chip operational amplifiers reduce the need for separate analog components, while 16 KB of Flash stores application firmware and 512 bytes of SRAM supports lightweight buffering and state management. SPI can accommodate higher-speed local peripherals, whereas UART or I2C supports lower-bandwidth instruments and configuration links. The mixed-signal integration is useful when traceability, component count, and low standby consumption matter. Production designs should confirm channel count, sampling characteristics, and analog-layout requirements using the complete manufacturer datasheet.
おすすめ
Low-Power Environmental Monitor
The MSP430F235TPM is appropriate for an environmental monitor that samples sensors infrequently and must conserve battery energy between measurements. Its documented five power-saving modes, 0.1 uA off-mode current with RAM retention, and less-than-6-microsecond standby wake-up allow the controller to remain responsive without running continuously. The integrated 10-bit ADC can acquire suitable sensor outputs, and the two operational amplifiers can provide conditioning where the source impedance and noise requirements permit. UART or I2C can report measurements to a local logger, while SPI supports faster sensors and removable storage. The engineer must select the final power mode, regulator topology, and sampling interval from the manufacturer current-consumption data to produce a defensible battery-life estimate.
おすすめ
Battery-Powered Instrumentation
The MSP430F235TPM can be used in battery-powered instrumentation that combines analog measurement with low-rate data logging or communications. The 16 MHz 16-bit RISC processor executes quickly, while the five low-power operating states permit the instrument to spend most of its time idle. Its 512 bytes of SRAM supports small working sets, and 16 KB of Flash accommodates firmware for acquisition control, calibration, and communication protocols. I2C and UART are useful for configuration interfaces and low-speed telemetry, while SPI can serve a display or memory device. Because the supplied data does not quantify active current, the final battery calculation must use the datasheet operating-current curves for the selected voltage, clock, and peripheral configuration.
おすすめ
Communications-Assisted Embedded Control
The MSP430F235TPM fits communications-assisted embedded control systems that need flexible serial connectivity alongside real-time processing. I2C supports short-distance sensor and peripheral connections, SPI supports faster external devices, and UART provides a conventional serial link to a modem, service tool, or supervisory controller. The 16 MHz CPU and 125 ns instruction cycle support deterministic control tasks, while the ADC and two operational amplifiers allow the same device to monitor an analog plant variable. Power-saving modes are valuable in remote or intermittently connected equipment. Designers should allocate the pins required by each interface, review whether peripherals can operate concurrently, and verify the package pin multiplexing in the MSP430F23x and MSP430F24x manufacturer datasheet.
おすすめ
Precision Control and Monitoring
The MSP430F235TPM can support precision control and monitoring designs that combine a moderately resolved measurement channel with embedded logic. Its 10-bit ADC is suitable for many closed-loop monitoring functions, and the two operational amplifiers can implement signal conditioning close to the controller. The 16-bit RISC architecture and 16 MHz clock allow control calculations to be interleaved with serial communication, while five power-saving modes help isolate the device from the operating profile. For an analog-heavy implementation, the principal benefits are reduced board area and shorter analog routing. The trade-off is that the supplied result does not provide the complete ADC input specification, reference requirements, or amplifier electrical limits; those details must be confirmed before setting precision expectations or compensation targets.

設計ノート
Use the manufacturer 64-LQFP land pattern and verify the package drawing before routing the board. Place the device so analog inputs and amplifier connections can remain away from high-current switching paths and digital clock lines. The supplied results do not provide the complete pin table, so do not infer analog or power-pin assignments from the family name. Confirm pin multiplexing, exposed-pad requirements, and programming access in the MSP430F23x and MSP430F24x datasheet before release.
Treat the 10-bit ADC and two operational amplifiers as a sensitive analog subsystem even though they share a mixed-signal package. Use a continuous ground reference, minimize loop area, separate analog and digital return currents where practical, and follow the manufacturer guidance for bypassing and reference routing. The supplied results do not provide ADC acquisition-time or amplifier noise specifications, so sampling timing and gain must be calculated from the full datasheet rather than assumed.
The verified data identifies five power-saving modes, 0.1 uA off-mode current with RAM retention, and standby wake-up in less than 6 microseconds. Use those values to define the intended duty cycle, but verify the exact operating mode and supply voltage in the manufacturer power-consumption graphs. Account for regulator quiescent current, sensor current, and communication activity when calculating battery life; a low MCU sleep current alone does not establish the complete system consumption.
Do not assume that every MSP430F2xx device with an LQFP package is interchangeable. Peripheral multiplexing, memory capacity, ADC architecture, amplifier count, operating-temperature grade, and active-mode limits can differ even within one family. Validate each replacement against the exact ordering table, pin table, memory map, interrupt vector, and application firmware. The alternatives listed here are same-brand candidates and still require manufacturer-datasheet confirmation before production use.
コンプライアンス情報
The supplied verified results do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Confirm these attributes on the current Texas Instruments product and ordering pages.
