MSP430G2333IPW20R Technical Specifications

MSP430G2333IPW20R Key Features

• One 16-bit RISC core that delivers more computational efficiency than typical 8-bit controllers, enabling faster math and control loops.
• Low-voltage operation (1.8?C3.6 V) so the device can run from single-cell Li-ion or multiple standard battery chemistries, improving design flexibility.
• Integrated ADC10 with multiple channels simplifies sensor interfacing and reduces external component count, which lowers BOM cost and board area.
• Multiple low-power modes and a watchdog timer that together extend battery life and increase system reliability under different duty cycles.

Typical Applications

• Battery-operated sensors and data loggers that require sub-??A standby current and occasional wake-up for measurement and transmission tasks.
• Simple industrial controllers that need deterministic timing, basic ADC measurements, and reliable operation across -40 ??C to +85 ??C.
• Consumer handheld controls and small appliances that benefit from compact 20-pin packaging and integrated peripherals to reduce PCB size.
• Power-sensitive metering and monitoring endpoints that require accurate analog inputs and minimal power draw during idle periods.

MSP430G2333IPW20R Advantages vs Typical Alternatives

The device provides a clear balance of performance and energy efficiency compared to typical 8-bit MCUs. Its 16-bit core delivers better arithmetic range and faster control algorithms, while multiple low-power modes reduce energy consumption versus higher-clocked alternatives. Integrated ADC and timers cut external parts and lower system cost. The 20-pin TSSOP package is smaller than many DIP options, enabling denser board designs and more compact products.
