MSP430G2433IPW28R Key Features

• Single 16-bit RISC core with compact instruction set for predictable, efficient control tasks and simple real-time loops.
• Integrated 10-bit ADC that reduces external analog components and speeds sensor acquisition for measurement applications.
• Low-voltage operation from 1.8 V to 3.6 V, enabling direct use with common battery chemistries and lower-power rails than many 32-bit alternatives.
• On-chip 16-bit Timer_A and serial USCI module for deterministic timing, PWM generation and UART/SPI/I2C connectivity without external controllers.

Typical Applications

• Battery-powered sensor nodes where long run-time and a small BOM are critical; the device minimizes external analog and timing parts and saves board area.
• Industrial control panels that need robust UART or SPI interfaces and deterministic timers for event scheduling and simple closed-loop control tasks.
• Handheld measurement instruments that require a 10-bit ADC for basic analog-to-digital conversion and low supply voltage operation for portability.
• Serial communication gateways that bridge RS-232/TTL or SPI peripherals to larger systems while maintaining low power consumption and compact packaging.

MSP430G2433IPW28R Advantages vs Typical Alternatives

The MSP430G2433IPW28R favors simplicity and energy efficiency over raw processing power.
