MSP430G2403IPW20 Technical Specifications

MSP430G2403IPW20 Key Features

• 16?bit ultralow?power core ?? reduces active and standby energy to extend battery life in handheld and remote designs.
• Wide supply range ?? 1.8 V to 3.6 V operation enables one?cell and multi?cell battery compatibility without external regulators.
• Compact 20?pin package ?? provides a smaller PCB footprint than larger MCUs while retaining essential GPIO and peripheral functions.
• Integrated peripheral set ?? timers and serial/analog resources simplify system design and lower BOM count for straightforward control tasks.

Typical Applications

• Battery?powered sensor nodes that require ultralow sleep currents, periodic wake?up to sample sensors, and simple local control logic for extended field life.
• Portable consumer devices with limited PCB space that need a compact microcontroller for menus, button handling, and low?power display driving.
• Industrial controllers where a small microcontroller performs supervisory tasks, simple serial communication, and watchdog or timing functions in constrained form factors.
• Energy?harvesting or remote telemetry endpoints that demand wide supply tolerance, microamp sleep currents, and reliable operation across -40 ??C to +85 ??C ambient ranges.

MSP430G2403IPW20 Advantages vs Typical Alternatives

Compared with larger or higher?power microcontrollers, this device offers much lower quiescent and active consumption thanks to the MSP430 ultralow?power architecture and multiple low?power modes. The 20?pin package delivers a smaller board footprint and fewer I/O than 28? or 40?pin parts, which reduces cost and assembly complexity for simpler designs. Wide 1.8?C3.6 V supply acceptance and industrial temperature rating make it more flexible than strictly 3.3 V?only devices. For compact, battery?sensitive applications, it balances integration and efficiency without excess features that add cost or power overhead.

MSP430G2403IPW20 Brand Info

The MSP430G2403IPW20 belongs to the MSP430 family from Texas Instruments, a long?established vendor of ultralow?power microcontrollers. TI positions the MSP430 line for energy?conscious embedded systems, offering comprehensive documentation, development tools, and ecosystem support tailored to rapid prototyping and production deployment.

FAQ

What package does IPW20 denote?

The suffix IPW20 indicates a 20?pin package variant. This package type provides a compact footprint and is commonly used for space?constrained PCB layouts that still require multiple general?purpose I/O and basic peripheral access.

What supply voltages are supported?

The device supports a wide supply range from 1.8 V up to 3.6 V, enabling operation from single?cell lithium sources or regulated 3.3 V rails. This range helps designers avoid external level?shifting in many battery?powered and portable applications.

Is this MCU suitable for battery?powered designs?

Yes. The MSP430 architecture emphasizes ultralow power with multiple low?power modes and microamp?class sleep currents, making it suitable for devices that spend most time in standby and require periodic wake?up to perform tasks.

Which temperature range does it support?

The device is rated for industrial temperature operation from -40 ??C to +85 ??C, allowing use in harsh ambient conditions and outdoor enclosures without additional thermal management for most embedded use cases.

Where can I find development resources?

Development tools, reference designs, and datasheets are available through the manufacturer??s documentation and toolchains. Reference material typically includes schematics, sample code, and recommended PCB layout practices for reliable system integration.
