MSP430G2432IPW14 Technical Specifications

MSP430G2432IPW14 Key Features

• One 16-bit CPU core that delivers efficient integer processing for control and measurement tasks.
• Integrated 10-bit ADC with multiple channels, enabling direct sensor interfacing without external A/D converters.
• Low-voltage operation (1.8?C3.6 V) for extended battery life and compatibility with 1.8 V and 3.3 V systems.
• Compact 14-pin TSSOP package, improving PCB space usage while retaining essential I/O and peripherals.

Typical Applications

• Portable sensor nodes and environmental monitors requiring ultra-low standby current and accurate 10-bit conversions for temperature, light, or humidity measurements over long battery life.
• Battery-powered metering and handheld instruments that need deterministic timing from a 16-bit timer and on-chip ADC to replace discrete analog front-ends.
• Embedded control in consumer and industrial devices where a small 14-pin package reduces BOM cost and board area while maintaining I2C or SPI connectivity for peripherals.
• Low-power data loggers and wearable devices that combine low operating voltage, compact footprint, and an integrated watchdog for reliable long-term operation.

MSP430G2432IPW14 Advantages vs Typical Alternatives

The device delivers a balance of low-power operation and integrated peripherals that often outperforms larger 8-bit microcontrollers in efficiency and performance per MHz. With a 16-bit core and on-chip 10-bit ADC, it reduces the need for external converters and offloads sensor processing from host controllers. Its 1.8?C3.6 V range and small 14-pin package make it more suitable than bulkier alternatives for space- and power-constrained designs. The integrated watchdog and brownout features also increase system reliability compared to minimal-feature MCUs.
