• Portable instrumentation where the 10-bit ADC and low-power modes reduce external components and extend battery run time significantly.
• Simple motor or actuator controllers that require reliable PWM generation and capture functions with a small board footprint.
• Serial bridge devices or IoT endpoints that use USI-based SPI/I2C interfaces to connect sensors and external memory with limited pin count.

MSP430G2332IRSA16R Advantages vs Typical Alternatives

The device blends a 16-bit core with integrated analog and timing peripherals. This yields higher computational efficiency and better analog performance than many 8-bit controllers in the same price class. Its multiple low-power modes cut standby consumption compared with comparable devices that lack deep sleep states. The small 16-pin package offers a more compact solution than larger microcontrollers while still providing up to a dozen usable I/O pins and on-chip ADC and serial interfaces for simpler system design.

FAQ

What core does it use?

The device uses a 16-bit RISC MSP430 CPU core. This core favors efficient code density and deterministic instruction timing for real-time embedded tasks.

What is the supply voltage?

It operates from 1.8 V to 3.6 V. This range supports common single-cell lithium and several battery chemistries without extra regulators in many designs.

Does it have an ADC?

Yes. The MCU includes a 10-bit analog-to-digital converter. That ADC reduces the need for external converters in sensor and measurement applications.

How many I/O pins are available?

The 16-pin package exposes around 12 general-purpose I/O pins. That count supports multiple digital sensors, control signals, and serial interfaces in compact designs.

Can it communicate over SPI or I2C?

Serial communication is provided via the USI block, which supports SPI-like and I2C-like protocols. This enables direct interfacing with common serial peripherals.
