MSP430F233TPM - 16MHz 16-Bit Ultra-Low-Power MCU | Texas Instruments
N.º de pieza: MSP430F233TPM ✓ ActivoMSP430F233TPM Descripción general
A microcontroller is a compact embedded-computer system that combines a CPU, memory, peripheral interfaces, and power-management functions on one integrated circuit. The MSP430 belongs to the mixed-signal microcontroller category, which extends the general embedded MCU hierarchy with analog conversion and comparison functions. Its 16-bit RISC architecture uses 16-bit registers and constant generators, while five low-power modes and fast standby wake-up support battery-powered and energy-conscious designs.
The MSP430F233 combines 8 KB Flash with 1 KB SRAM and a maximum clock frequency of 16 MHz. Its 12-bit ADC enables analog measurement, and the integrated comparator supports thresholding and basic signal conditioning. Four USCI modules provide serial connectivity for I2C, SPI, and UART configurations. Two 16-bit timers support timing, capture, compare, and periodic event generation, making the device useful for sensor acquisition, industrial control, and compact embedded measurement systems.
The MSP430F23x family is designed around a mixed-signal architecture and low-power operation. The FLL+ frequency-locked-loop system supports clock control, while the CPU provides a 125 ns instruction cycle at 16 MHz according to the family technical description. The device can operate across multiple low-power states, including standby and RAM-retention off modes, allowing firmware to reduce activity when the application does not require continuous processing.
Typical uses include low-power sensor nodes, battery-operated instrumentation, industrial meters, building-control endpoints, compact motor-control interfaces, and connected IoT devices. The 12-bit ADC is useful for battery, temperature, potentiometer, and analog sensor interfaces, while USCI peripherals simplify communication with external sensors, displays, transceivers, and data loggers. The LQFP package provides accessible leads and is suitable for through-hole assembly or conventional board-level manufacturing processes.
Designers should pay attention to the 1.8 V to 3.6 V supply range, peripheral pin multiplexing, clock configuration, and low-power state transitions. Place decoupling capacitors close to the supply pins, follow the pin-description table in the manufacturer datasheet when allocating I/O, and confirm the ADC input range and accuracy requirements for the selected operating conditions. For battery systems, account for standby and wake-up current alongside active-mode consumption.

Aplicaciones típicas
MSP430F233TPM es adecuado para 6 aplicacións: Battery-Powered Sensor Node, Industrial Metering Instrument, Low-Power Data Acquisition Front End, Connected IoT Endpoint, Compact Motor-Control Interface, Portable Environmental Monitor.
Battery-Powered Sensor Node
The MSP430F233TPM fits battery-powered sensor nodes because its MSP430 architecture provides five low-power modes, 0.3 uA standby current, and 0.1 uA off current with RAM retention. A typical design wakes the MCU to sample a resistive or temperature sensor through the 12-bit ADC, stores the result in 1 KB of SRAM, and uses an external serial interface to report the measurement. The 1.8 V to 3.6 V operating range also supports low-voltage energy-storage systems. Design the firmware to keep the CPU and unused peripherals disabled between measurements, and verify the complete sleep-current budget including pull resistors and external sensor leakage.
Recomendado
Industrial Metering Instrument
The MSP430F233TPM is suitable for industrial metering instruments that combine analog measurement with low-power processing. Its 12-bit ADC can sample voltage or sensor outputs, while two 16-bit timers support periodic sampling, debounce timing, and display updates. I2C or SPI can connect a display, external memory, or a communications module, and UART supports a simple host interface. The -40 C to +105 C operating range suits industrial equipment. Keep analog and digital return paths separated on the PCB, provide local decoupling, and calibrate the ADC path for the actual divider, reference, and signal bandwidth used in the meter.
Recomendado
Low-Power Data Acquisition Front End
The MSP430F233TPM can serve as the control and acquisition MCU in a compact data-acquisition front end. The fast 12-bit ADC supports digitizing slowly changing or externally conditioned analog signals, while the 16-bit RISC CPU performs scaling, filtering, thresholding, and data packing before transmission. The device’s 16 MHz maximum clock provides useful processing headroom without requiring a higher-power system architecture. For remote acquisition, the standby and RAM-retention modes reduce energy between sample bursts. Use the manufacturer’s recommended ADC input and reference arrangement, and check acquisition timing and output-noise requirements against the selected signal source.
Recomendado
Connected IoT Endpoint
The MSP430F233TPM is useful for small connected IoT endpoints that must monitor a local signal and communicate with a host or peripheral network. USCI channels provide I2C, SPI, or UART options for sensors, radio modules, displays, and configuration interfaces. At 16 MHz with a 16-bit architecture, the MCU can handle protocol framing, sensor management, and low-power scheduling while using only 8 KB of Flash and 1 KB of SRAM. Keep the wireless module’s supply current and transmission timing outside the MCU’s sleep budget where possible, and use the integrated comparator for threshold or presence detection when appropriate.
Recomendado
Compact Motor-Control Interface
The MSP430F233TPM can be used as the supervisory controller in a compact motor-control or actuator interface. Its timers provide timing references for PWM-related sequencing and periodic control tasks, while the comparator can monitor a feedback signal and the ADC can supervise a sensor or supply level. The 64-pin LQFP package exposes the required digital and analog resources for a conventional control board. Keep motor power switching on a separate power stage, use appropriate isolation and protection between the MCU and driver circuitry, and verify that control-loop timing remains within the MCU’s clock and peripheral limits.
Recomendado
Portable Environmental Monitor
The MSP430F233TPM is appropriate for a portable environmental monitor that periodically measures temperature, humidity, light, or gas-related sensor outputs. The 12-bit ADC and integrated comparator allow the firmware to combine quantitative readings with simple threshold events, while I2C or SPI supports common digital sensors. The MCU’s low-power modes help extend operating time between service intervals, while the -40 C to +105 C range provides useful industrial flexibility. Use the device’s 1.8 V to 3.6 V supply range to design the sensor and regulator interface, and account for sensor self-heating, ADC input settling, and enclosure temperature gradients during calibration.

Notas de diseño
Design the supply network for the MSP430F233TPM operating range of 1.8 V to 3.6 V, and place the required bypass capacitors close to the device power pins according to the manufacturer layout guidance. The MCU can enter 0.3 uA standby and 0.1 uA off-with-RAM-retention states, but the complete system current will also include sensor bias, pull resistors, communications hardware, and regulator quiescent current. Measure the assembled product in each operating mode rather than relying only on the MCU current figures.
Use the manufacturer 64-pin PM package drawing and pin-description table to create the PCB footprint and assign alternate-function pins. Keep analog inputs, comparator inputs, voltage references, and associated return paths away from switching nodes and high-current traces. Route the reset and clock connections according to the device guidance, and preserve a clean ground reference for the ADC and comparator subsystem. A footprint drawing alone does not establish electrical compatibility.
Do not select a replacement solely because it has a 64-pin LQFP package. MSP430 devices can differ in pin multiplexing, memory size, converter features, clock architecture, timers, and temperature grade. For a substitution, compare the exact device orderable part, pin list, peripheral mapping, electrical limits, and package drawing. The MSP430F233TPMR ordering variant is the closest confirmed alternative, but the production change should still be checked against assembly and marking requirements.
