MSP430G2233IPW20 Key Features

• Single 16-bit core with compact code density for lower memory footprint and faster execution in control tasks.
• Integrated Flash and RAM on-chip, enabling field-upgradeable firmware and reduced BOM compared with external-memory alternatives.
• Low-voltage operation (1.8 V?C3.6 V) and ultra-low-power design that extends battery life in portable or remote sensor applications.
• Rich peripheral mix including a 16-bit timer and USI to support precise timing and multiple serial protocols without extra components.

Typical Applications

• Battery-powered sensor nodes where low current draw and fast wake-up are essential to maximize service life over months or years.
• Handheld controls and user interfaces that require compact firmware, multiple GPIOs, and reliable serial link options for peripherals.
• Industrial monitoring and metering equipment that demand industrial temperature operation and deterministic 16-bit timer control.
• Cost-sensitive consumer devices that benefit from integrated Flash and RAM to avoid external memory and reduce assembly complexity.

MSP430G2233IPW20 Advantages vs Typical Alternatives

The device delivers a tighter size-to-function ratio versus many 8-bit microcontrollers by combining a 16-bit core with on-chip flash and RAM. Compared with larger MCUs, it reduces BOM costs and power consumption while still providing up to 16 MHz performance and standard serial interfaces. Industrial temperature rating and a 20-pin TSSOP package make it more suitable for compact, rugged installations than bulkier options. For designs that prioritize low energy per operation and fewer external components, this part offers clear efficiency and integration advantages.
