MSP430G2553IN20 - 16MHz 16KB Flash MCU | Texas Instruments
Référence : MSP430G2553IN20 ✓ ActifMSP430G2553IN20 Présentation
A mixed-signal microcontroller combines a digital processor, analog measurement circuitry, communications interfaces, and timing resources within one device. The MSP430G2553 belongs to the MSP430 family of ultra-low-power microcontrollers and targets applications that require deterministic control, efficient peripheral integration, and low standby consumption. Its architecture supports portable instruments, sensing nodes, data acquisition modules, and small embedded-control systems.
Key features include a 16-bit RISC CPU operating at up to 16 MHz, 16 KB of Flash, 512 bytes of SRAM, a 10-bit ADC, an analog comparator, UART, SPI, I²C, and timers. The integrated peripherals reduce external component count and allow compact designs that measure analog inputs while exchanging data with external sensors, displays, or host systems. The manufacturer identifies the device for low-power portable measurement applications.
The MSP430 architecture uses 16-bit registers and an interrupt-oriented peripheral model. Its mixed-signal resources support sensor conditioning and threshold comparison without requiring a separate analog processor, while UART, SPI, and I²C interfaces provide paths to external integrated circuits. The 20-pin PDIP package also exposes the device through a conventional through-hole footprint suitable for prototyping, education, and industrial control boards.
Typical uses include battery-powered measurement instruments, simple data loggers, environmental sensors, industrial sensing nodes, keypad interfaces, and compact embedded-control products. UART, SPI, or I²C can connect a sensor module or local display, while the ADC and comparator support analog measurement. The MSP430G2553IN20 is also widely used as the target device for MSP430 LaunchPad-style development and educational projects.
Designers should verify the exact pin functions and peripheral multiplexing against the manufacturer datasheet before laying out the PCB. Decoupling, grounding, unused-pin handling, clock configuration, and low-power mode sequencing are critical in a compact mixed-signal design. The verified data does not provide a complete pin-level mapping, so pin names and electrical details not explicitly supplied are marked as needed rather than inferred.

Applications typiques
MSP430G2553IN20 convient pour 6 applications: Battery-powered portable measurement instrument, Environmental sensor node, Simple industrial data logger, Embedded keypad and display controller, Portable medical or diagnostic sensor interface, Battery-powered IoT sensor.
Battery-powered portable measurement instrument
The MSP430G2553IN20 fits portable measurement instruments because it combines a 16 MHz 16-bit RISC CPU, 16 KB of Flash, 512 B of SRAM, and five low-power modes in one 20-pin PDIP device. Its integrated 10-bit ADC and comparator allow the controller to acquire and interpret analog signals while the UART, SPI, or I²C interface connects a sensor or display. In a battery-powered design, firmware can use a low-power mode between measurements rather than leaving the CPU and unused peripherals active continuously. The verified Texas Instruments product description specifically positions the MSP430 family for portable measurement applications.
Recommandé
Environmental sensor node
For an environmental sensor node, the MSP430G2553IN20 can sample an analog sensor through its 10-bit ADC and use the comparator for threshold decisions before transmitting a result. Its UART, SPI, and I²C interfaces provide flexible options for connecting a temperature, humidity, pressure, or air-quality sensor module. The 16 MHz CPU and 16 KB Flash memory are sufficient for compact acquisition and communication firmware, while 512 B of SRAM supports short working buffers. Selecting a low-power mode during sensor idle periods is important when the node is expected to operate from a small battery or energy-harvesting source.
Recommandé
Simple industrial data logger
The MSP430G2553IN20 can serve as the control and logging MCU in a compact industrial data logger. Its 10-bit ADC is suitable for sensors with analog outputs, while the comparator can provide fast threshold events and timer resources can establish periodic logging intervals. UART or I²C can connect a nonvolatile storage device, host controller, or local communication module. The 20-pin PDIP package through-hole footprint is useful for prototypes and repairable industrial equipment, but designers must validate grounding, input protection, and analog signal conditioning for the deployed environment.
Recommandé
Embedded keypad and display controller
The MSP430G2553IN20 can manage a keypad, indicator, or small local display while supervising a sensor-oriented application. Its multiple I/O pins and integrated timers support debounced key scanning, periodic display updates, and event scheduling, while UART, SPI, and I²C provide flexible links to display and storage devices. The 16 MHz 16-bit CPU allows firmware to combine input handling with analog monitoring and serial communication. Because the verified data does not provide a complete pin map, the exact signal assignment should be based on the manufacturer datasheet and the selected external display interface.
Recommandé
Portable medical or diagnostic sensor interface
The MSP430G2553IN20 can be evaluated as the embedded controller in a low-power diagnostic sensor interface when the design requires local analog acquisition and serial communication. Its 10-bit ADC, comparator, and 16 MHz CPU provide basic signal conditioning and control functions, while the low-power architecture is relevant to portable equipment. The integrated ADC is not a substitute for application-specific medical signal conditioning, isolation, calibration, or safety validation. Those requirements must be addressed by the surrounding analog and mechanical design, and the manufacturer documentation should be consulted before using the MCU in a regulated medical product.
Recommandé
Battery-powered IoT sensor
The MSP430G2553IN20 is a plausible fit for a small battery-powered IoT sensing module because it combines low-power modes, 16 KB Flash, 512 B SRAM, and serial interfaces in a 20-pin package. A sensor can feed the ADC or comparator, while UART, SPI, or I²C connects a radio, gateway, or local storage element. The 16 MHz CPU is more than sufficient for simple thresholding, sampling, and protocol framing, but wireless communication usually requires a separate transceiver. Power consumption should be evaluated using the selected radio duty cycle and the MCU’s configured idle mode rather than the maximum clock specification alone.

Notes de conception
Configure the MSP430G2553IN20 for the actual duty cycle instead of leaving the CPU running at its 16 MHz maximum. The verified manufacturer description identifies five low-power modes, so use the appropriate idle mode between measurements and disable unused peripherals in firmware. Actual battery-life calculations require the selected clock, active duration, standby duration, and peripheral current values, which are not supplied in the verified data.
Place the required supply bypass components close to the device power pins and route analog sensor inputs away from switching nodes and serial communication traces. The verified data confirms a 3.3 V to 3.6 V supply range but does not provide a complete pinout or recommended capacitor values, so use the Texas Instruments datasheet and board-layout guidance before finalizing the PCB.
Do not treat related MSP430G2xx order codes as drop-in replacements without checking the manufacturer datasheet. The supplied cross-reference results mention MSP430G2252IN20 and MSP430G2452IN20, but do not verify their memory, clock, peripheral, or pin-level compatibility with MSP430G2553IN20. Validate package, pin names, supply limits, peripheral multiplexing, and firmware support before substitution.
Informations de conformité
The supplied verified web data does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status for MSP430G2553IN20.
