• Multiple timers and serial interfaces for deterministic control and flexible comms, simplifying system integration.
• DMA engine for efficient peripheral data transfer that reduces CPU overhead and saves cycles.
• Wide supply range (1.8?C3.6 V) to support both lower?voltage and standard 3.3 V systems without additional regulators.
• Industrial temperature rating for reliable operation in harsher environments compared to consumer?grade parts.
• Compact 64?pin package that balances I/O density with board area for space?sensitive designs.

Typical Applications

• Battery?powered sensor nodes and portable instruments that need long run time and precise 12?bit analog measurement across multiple channels.
• Smart metering and energy monitoring units requiring reliable low?power MCU operation and on?chip flash for firmware updates.
• Industrial control modules where deterministic timers, serial interfaces and an industrial temperature range improve system robustness.
• Embedded human?machine interfaces and motor control submodules that benefit from DMA?assisted data movement and multiple communication ports.

MSP430F5437AIPN Advantages vs Typical Alternatives

This device combines low power consumption with on?chip 128 KB flash and 8 KB RAM, offering more integrated memory than many entry?level MCUs. Its 16?bit CPU gives better code density and lower energy per instruction versus equivalent 32?bit parts in low?power modes. Integrated DMA and a 12?bit ADC outperform simpler MCU alternatives by offloading the CPU and improving analog resolution. The wide 1.8?C3.6 V range and industrial temperature rating make it more adaptable across designs than consumer?grade microcontrollers.

FAQ

What is the CPU clock speed?

Maximum core speed operates up to 25 MHz. Design margins should account for peripheral timing and low?power modes that reduce effective processing frequency when enabled.

How much flash memory is available?

The device provides 128 KB of on?chip flash memory. This supports moderate firmware size, in?field updates and storage of configuration data without external memory.

What ADC resolution does it have?

It includes a 12?bit ADC. That resolution gives finer measurement steps and better dynamic range than 8?bit converters in many alternative MCUs.

What supply voltage range is supported?

Supply voltage ranges from 1.8 V to 3.6 V. This lets designers use the MCU in both lower?voltage and standard 3.3 V systems without additional power conversion in many cases.

Which package does it use?

The part is available in a 64?pin LQFP package. This offers a balance of I/O count and PCB footprint for mid?density embedded designs.
