MSP430G2232IPW20 Technical Specifications

MSP430G2232IPW20 Key Features

• Ultra-low-power 16-bit core providing efficient processing and longer battery life compared with many 8-bit controllers.
• Integrated 10-bit ADC with multiple channels for direct sensor interfacing and reduced external component count.
• 16-bit Timer_A that supports precise timing, PWM generation and capture for motor control or timing-critical tasks.
• Compact TSSOP-20 package that enables smaller board area and simpler routing compared to larger 28-pin or 40-pin alternatives.

Typical Applications

• Battery-powered sensor nodes where low active and standby currents extend battery life and reduce maintenance intervals for remote deployments.
• Handheld instrumentation that needs a small 20-pin package, integrated ADC, and precise timers for measurement and user interface control.
• Consumer control panels and remote controls requiring compact size, reliable GPIO, and analog inputs for knobs, buttons, and sensors.
• Industrial I/O modules where operation across -40 ??C to +85 ??C and integrated peripherals reduce the need for external analog or timing ICs.

MSP430G2232IPW20 Advantages vs Typical Alternatives

The device combines a 16-bit MSP430 core with a 10-bit ADC and 16-bit timer in a 20-pin TSSOP. Compared to many 8-bit parts, it delivers higher arithmetic performance and more efficient code density.
