• Low-voltage operation from 1.8 V to 3.6 V, making it suitable for single-cell battery systems and 3.3 V rails.
• Multiple 16-bit timers for precise PWM and timing control in motor drives, power supplies, and time-critical tasks.
• Compact 38-pin TSSOP package that balances pin count against PCB footprint for space-constrained applications.
• Industrial temperature rating (-40 ??C to +85 ??C) to ensure reliable operation in harsh or outdoor environments.

Typical Applications

• Battery-powered sensor nodes that require long sleep life and periodic 10-bit ADC sampling for environmental monitoring and telemetry.
• Industrial control panels where deterministic timer-driven control and multiple serial ports reduce component count and simplify schematics.
• Consumer handheld instruments that need a compact 38-pin footprint, low operating voltage, and precise timers for user interface and measurement tasks.
• Power-management and battery-charging circuits using low-power modes and 16-bit timers to implement efficient, real-time control routines.

MSP430G2755IDA38 Advantages vs Typical Alternatives

The MSP430G2755IDA38 provides a more energy-efficient option compared with many 8-bit microcontrollers, thanks to its 16-bit core and sub-microamp low-power modes. With integrated 10-bit ADC, dual USCI serial controllers, and multiple 16-bit timers, it reduces external component count and board complexity. Its 1.8 V?C3.6 V supply range and industrial temperature rating make it better suited for both battery-driven and industrial systems than higher-voltage or consumer-only alternatives.
