MSP430G2332IPW14R Technical Specifications

MSP430G2332IPW14R Key Features

• 16-bit core that delivers compact code density and faster arithmetic than many 8-bit alternatives.
• Low-voltage operation from 1.8 V to 3.6 V, which matters for battery life and compatibility with modern sensor supplies.
• 10-bit ADC integrated on-chip to digitize analog sensors without an external converter, reducing board area and BOM cost.
• Timer_A with capture/compare registers that simplifies precise PWM and timing compared to software-only timing approaches.
• USI serial block that supports I2C or SPI protocols for flexible peripheral interfacing and faster system integration.
• Five low-power modes that enable lower standby currents and longer battery life than many general-purpose microcontrollers.
• Small 14-pin TSSOP package offering a smaller footprint and lower cost versus larger pin-count packages.

Typical Applications

• Battery-powered sensor modules that require ultra-low standby current, local 10-bit ADC conversion, and a compact 14-pin footprint for space-constrained enclosures.
• Simple industrial controllers where deterministic Timer_A events, I2C or SPI peripheral links, and 1.8 V to 3.6 V compatibility simplify system design and reduce components.
• Portable medical or wearable devices that need a small package, lower power draw in sleep modes, and an integrated ADC to measure analog signals directly.
• Consumer electronics user interfaces with limited I/O, where the MCU provides debouncing, PWM-driven indicators, and low-power idle between user interactions.

MSP430G2332IPW14R Advantages vs Typical Alternatives

The device favors lower power and smaller size over raw peripheral count. Compared to many 8-bit parts, it uses a 16-bit RISC core for denser code and faster math. Compared to larger MCUs, it offers a smaller 14-pin package and fewer pins to route, which reduces board area and cost. The integrated 10-bit ADC and USI block mean fewer external components, and the five low-power modes enable longer battery life in typical embedded tasks.

FAQ

What is the maximum clock speed?

The maximum internal clock frequency is 16 MHz. Designers can scale the clock lower for reduced power consumption and use the DCO or external clock sources depending on timing needs.

Which serial interfaces are available?

This device provides a USI block that can be configured for I2C or SPI operation. That single serial block lets you connect common peripheral ICs without adding a separate UART peripheral.

How many ADC channels are supported?

The on-chip ADC offers 10-bit resolution and supports multiple input channels. You can digitize several analog sensors directly, which reduces component count and simplifies PCB routing.

What power modes are available for battery designs?

There are five low-power modes (LPM0?CLPM4). Each mode progressively turns off system resources to minimize current draw, giving designers flexibility for optimizing active versus standby energy use.

Which package should I order for compact PCBs?

The PW package is a 14-pin TSSOP. It is well suited for compact PCBs and surface-mount assembly while keeping a low component footprint and easy routing for modest I/O counts.
