MSP430G2955IDA38R Technical Specifications

MSP430G2955IDA38R Key Features

• Single 16?bit core for compact control code and efficient integer math.
• Low voltage operation across a 1.8?C3.6 V range, enabling battery and energy?harvesting systems.
• 38?pin TSSOP footprint offers more I/O and peripheral access than smaller SOT packages while maintaining a small board footprint.
• Ultra?low power family heritage reduces standby and active energy use for longer field life in remote devices.

Typical Applications

• Battery?powered metering and data acquisition nodes that require long standby life and reliable timing for periodic sampling and wireless bursts.
• Industrial sensor controllers where tight thermal and voltage margins demand a 1.8?C3.6 V tolerant MCU and predictable low?power modes.
• Handheld user interfaces and portable instruments needing compact 38?pin packages for multiple GPIOs, ADC inputs, and serial peripherals in a small PCB area.
• Embedded motor or actuator controllers that benefit from a 16?bit MCU for control algorithms and low standby current while preserving board space.

MSP430G2955IDA38R Advantages vs Typical Alternatives

The device combines a 16?bit core with a small 38?pin TSSOP package, offering a better balance of I/O density and compact size than many 20? to 28?pin alternatives. Its 1.8?C3.6 V operating range and low?power lineage yield lower average system consumption compared with general?purpose 8? or 32?bit MCUs in similar footprints. For designs prioritizing energy efficiency and deterministic control, this part provides more direct peripheral access and simpler power?mode management than larger, more complex microcontrollers.
