This device balances minimal code memory and RAM with low active and standby currents to reduce system power. For purchasing and manufacturer references visit IC Manufacturer.

MSP430G2302IN20 Technical Specifications

MSP430G2302IN20 Key Features

• Single 16?bit CPU core that delivers efficient instruction throughput for control and timing tasks.
• Low supply range (1.8?C3.6 V) and low active/standby currents to extend battery life in portable products.
• Integrated 16?bit Timer_A for precise timing, PWM and event capture, reducing external component count.
• Universal Serial Interface (USI) provides SPI/UART capability to interface with sensors or comms modules.

Typical Applications

• Battery-powered sensor nodes where ultra?low current consumption and simple timing control reduce overall system power draw.
• Consumer handheld devices that require simple user interface control, debounce timing and serial communication with minimal firmware footprint.
• Industrial control panels that use through?hole mounting for mechanical robustness and need reliable low?voltage operation across temperature.
• Legacy system upgrades where a small DIP package and basic peripherals allow drop?in replacement with lower power and comparable I/O.

MSP430G2302IN20 Advantages vs Typical Alternatives

The MSP430G2302IN20 offers a lower power profile and simpler peripheral set compared with larger MCUs. Its 16?bit core gives more efficient code density than many 8?bit parts, often resulting in smaller firmware and fewer flash writes. The small 20?pin DIP package supports quick prototyping and easy mechanical mounting versus surface?mount only parts. For designs that need basic timing, a serial link and comparator without ADC overhead, it provides a compact, cost?effective choice.

FAQ

What core does it use?

The device uses a 16?bit MSP430 RISC core. This core is optimized for low active power and compact code size, making it suitable for simple control and timing tasks in embedded systems.

What is the operating voltage?

Supply voltage ranges from 1.8 V to 3.6 V. That span supports common single?cell lithium and alkaline battery supplies while preserving stable MCU operation across the specified range.

Does it include an ADC?

This variant includes an on?chip comparator but does not provide a multi?channel ADC. Designers needing analog measurement must add an external ADC or select a different MSP430 variant that includes ADC10 functionality.

Which communication interfaces exist?

The chip provides a Universal Serial Interface (USI), usable for SPI or UART modes. USI enables simple serial links to sensors and modules without a full hardware UART peripheral.

Is it suitable for harsh environments?

The device is specified for an industrial temperature range from ?40 ??C to +85 ??C. This makes it appropriate for many industrial and outdoor applications when combined with proper system design.
