MSP430G2333IRHB32T Technical Specifications

MSP430G2333IRHB32T Key Features

• Single 16-bit RISC core with deterministic instruction timing for faster control-loop response.
• Low-voltage operation from 1.8 V to 3.6 V, which matters for longer battery life and wider supply choices.
• Integrated 16-bit timer modules for precise pulse generation and event timing, reducing external component count.
• Multiple low-power modes that lower quiescent current and improve energy efficiency in duty-cycled systems.

Typical Applications

• Battery-operated sensor nodes that require long standby life and periodic wake-up for measurements and reporting.
• Portable medical instruments where compact 32-pin packages and low power extend operating time between charges.
• Simple industrial controllers that need robust watchdog protection and reliable timing in harsh temperature ranges.
• Consumer handheld devices needing compact MCU functionality, deterministic I/O timing, and low sleep current.

MSP430G2333IRHB32T Advantages vs Typical Alternatives

The device stands out with a 16-bit architecture that delivers better code density and lower active current than many 8-bit alternatives. The lower supply requirement of 1.8?C3.6 V supports smaller battery stacks. The integrated 16-bit timer and watchdog reduce external parts and system cost. Multiple low-power modes provide clear energy savings versus general-purpose MCUs with fewer sleep states.
