MSP430I2041TPWR Technical Specifications

MSP430I2041TPWR Key Features

• Single 16?bit core delivering compact code density, enabling lower memory requirements and smaller firmware footprint.
• Low operating voltage range (1.8?C3.6 V) for flexible battery and system power designs, reducing the need for extra regulators.
• Very low standby currents that extend battery life and permit longer maintenance intervals in remote or portable systems.
• Integrated analog and digital peripherals that reduce external component count and improve system reliability.

Typical Applications

• Battery?powered sensors and transducers where long idle times and short active bursts demand minimal standby current and efficient wake?up.
• Industrial control nodes with constrained PCB space that need a 16?bit MCU with sufficient GPIO and integrated analog front end for basic I/O and timing.
• Handheld instruments and portable meters requiring a small package, low power consumption, and predictable operating voltage range for battery operation.
• Simple human?machine interfaces and keypads where modest firmware size, timers, and serial interfaces meet product requirements without external controllers.

MSP430I2041TPWR Advantages vs Typical Alternatives

The device combines a 16?bit core with very low active and standby currents, offering a stronger power?efficiency tradeoff versus many 8? and 32?bit alternatives.
