• Single 16-bit Timer_A providing precise timing and PWM generation for control, sensing and power management tasks.
• Universal Serial Interface (USI) supporting SPI and I2C to connect sensors and peripherals with fewer external components.
• Up to 16 general-purpose I/O pins for direct sensor, actuator and user-interface connections in a small footprint.
• Small 20-pin package for space-constrained PCBs while preserving necessary peripheral access and testability.
• Industrial temperature rating to meet robustness needs in factory, field, and outdoor installations.

Typical Applications

• Battery-operated sensor nodes where low active and sleep currents extend runtime and a small 20-pin package reduces PCB area for cost-sensitive deployments.
• Handheld control panels requiring simple human interface support, PWM outputs for indicators, and a serial bus for communicating with modules.
• Industrial monitoring instruments that need a hardened temperature range, reliable timer functions, and local non-volatile storage for firmware.
• Consumer devices such as remote controls and simple appliances where minimal BOM, single-cell supply operation, and basic serial connectivity are priorities.

MSP430G2232IN20 Advantages vs Typical Alternatives

The device targets designs where low power, compact size, and basic peripheral integration matter more than abundant memory or high processing throughput. Compared with larger MCUs, it offers fewer external components, a smaller PCB footprint, and lower standby current. Its 16-bit core delivers better code density than many 8-bit alternatives, while the built-in flash and USI reduce the need for external memory and serial converters. That combination lowers system cost and shortens time to market for simple embedded applications.
