MSP430G2332IPW20R Technical Specifications

MSP430G2332IPW20R Key Features

• 16-bit core for compact code and efficient integer math, improving throughput over 8-bit alternatives.
• 1.8?C3.6 V operation for direct use with common battery chemistries, enabling longer run time and simpler power design.
• Five low-power modes (LPM0?CLPM4) to reduce energy use in sleep states and extend battery life compared to single-mode MCUs.
• Timer_A with 3 CCRs to handle PWM, capture and compare tasks without external logic, saving board space and BOM cost.
• USI module supporting SPI and I2C communication for flexible peripheral and sensor interfacing.
• 20-pin TSSOP package for compact PCB footprint and higher density compared with larger DIP or QFN parts.
• Industrial temperature rating (-40 to +85 ??C) for reliable operation in harsher or outdoor environments.
• On-chip watchdog for basic system reliability and recovery from software faults.

Typical Applications

• Battery-powered sensor nodes and wireless endpoints where low-voltage operation and multiple low-power modes extend field battery life and reduce maintenance.
• Handheld measurement tools that need compact boards and reliable timing for sampling, display updates, and user input handling in a tight 20-pin footprint.
• Industrial control interfaces requiring robust operation across -40 ??C to +85 ??C, with simple SPI or I2C links to sensors and actuators for local processing and control.
• Consumer appliances and metering devices where a small microcontroller provides PWM control, system supervision, and serial communications with minimal BOM cost and PCB area.

MSP430G2332IPW20R Advantages vs Typical Alternatives

The device offers a 16-bit CPU and five low-power modes, giving better compute efficiency and finer power control than many 8-bit MCUs. Its 1.8?C3.6 V range matches modern battery chemistries and allows direct connection to sensors that operate at similar voltages. The integrated Timer_A with three capture/compare registers and a USI module reduce the need for external timers and serial bridges. In a 20-pin TSSOP, the part delivers higher integration per board area than larger packages, while still meeting industrial temperature requirements.

FAQ

What supply voltages does it accept?

The device accepts a single-supply range of 1.8 V to 3.6 V. This range supports common battery chemistries and allows interface to low-voltage sensors without extra regulators.

Which package and pin count is used?

This part ships in a 20-pin TSSOP package (PW). The package offers a small PCB footprint and is suitable for compact board layouts and automated assembly processes.

Is it suitable for industrial use?

Yes. The industrial temperature grade covers -40 ??C to +85 ??C, making the device appropriate for many commercial and industrial applications where broader temperature tolerance is required.

What serial interfaces are available?

It includes a Universal Serial Interface (USI) module that can be configured for SPI and I2C operation. This enables direct connection to common sensors, displays, and external memories.

How does it help battery-powered designs?

Multiple low-power modes (LPM0?CLPM4) and low-voltage operation reduce average system power. The integrated timer and serial module also cut external component count, lowering system power and cost.
