MSP430G2303IPW28R Technical Specifications

MSP430G2303IPW28R Key Features

• Single 16?bit RISC core delivering efficient control for basic embedded tasks.
• Ultra?low supply range (1.8?C3.6 V) enabling direct operation from common batteries and low?voltage rails.
• Small flash and SRAM footprint (2 KB flash, 128 B RAM) reduces BOM cost for simple firmware.
• 28?pin TSSOP package offers a compact board footprint while keeping up to 20 GPIO available.
• Low?power modes permit extended battery life through deep standby and selective peripheral shutdown.
• On?chip watchdog and timer improve reliability and deterministic timing for control loops and wake events.

Typical Applications

• Simple battery?powered sensor nodes that require low quiescent current and occasional wake for measurement and reporting.
• Basic user interfaces and control panels where a small MCU provides debouncing, LED drive, and button scanning with minimal firmware.
• Portable handheld devices that need low?cost control, timing, and power management in a compact 28?pin package.
• Industrial or consumer sensor front ends that require a robust ?40 ??C to 85 ??C operating range and deterministic timer resources.

MSP430G2303IPW28R Advantages vs Typical Alternatives

This device favors simplicity and efficiency. Compared with larger 8/16?bit MCUs, it offers a true 16?bit core with lower code memory and RAM requirements, which reduces unit cost. The narrow 1.8?C3.6 V supply window and multiple low?power modes give longer battery life versus less optimized alternatives. In compact systems, the 28?pin TSSOP balances pin count and board area better than larger packages. For designs needing modest peripherals and tight power budgets, this part provides a concise, reliable solution.
