MSP430G2432IPW20 Key Features

• Single 16-bit core with compact instruction set for efficient code density and predictable real-time control.
• Integrated 10-bit ADC (multiple channels) for direct sensor interfacing and reduced external component count.
• Multiple low-power modes that cut system energy use and extend battery life in portable or remote applications.
• On-chip Flash and SRAM for flexible firmware updates and small program footprints without external memory.
• USCI serial module enabling UART, SPI, and I2C with fewer external interface components and simpler PCB routing.
• 20-pin TSSOP package that balances small board area with sufficient I/O and analog access.

Typical Applications

• Battery-powered sensor nodes where ultra-low standby current and a 10-bit ADC reduce power and part count while maintaining reliable data acquisition.
• Handheld instrumentation that needs fast wake-up, compact firmware in Flash, and multiple timers for accurate measurement timing control.
• Embedded control panels that use multiple serial links (UART/SPI/I2C), small footprint, and low-voltage operation for system-level integration.
• Home automation endpoints where minimal BOM, low-power sleep modes, and on-chip analog conversion simplify design and extend device lifetime.

MSP430G2432IPW20 Advantages vs Typical Alternatives

The device offers a smaller package and lower active and standby power than many 8/32-bit alternatives while keeping a 16-bit CPU for better arithmetic efficiency. It integrates a 10-bit ADC, two 16-bit timers, and a multi-protocol USCI module, reducing external components and board area. The on-chip Flash and modest SRAM are well matched to compact firmware, allowing faster time-to-market and fewer supply-chain parts compared with designs that need external memory or separate analog front-ends.

FAQ

What package does it use?

This part is supplied in a 20-pin TSSOP package (PW). The package provides a compact footprint while keeping access to multiple GPIO, analog, and serial pins on a standard 0.65 mm pitch.

What is the supply voltage range?

The device operates from a low-voltage supply range of 1.8 V to 3.6 V. This range supports common battery chemistries and 3.3 V systems while enabling low-power operation across many embedded designs.

How much on-chip memory is available?

The MCU includes on-chip Flash memory for program storage and on-chip SRAM for runtime data. This combination enables firmware updates in the field and keeps board-level complexity lower than alternatives requiring external memory.

Which serial interfaces are supported?

A flexible USCI module supports standard UART, SPI, and I2C communication. This allows interfacing with sensors, peripherals, and host processors using fewer external interface chips.

Is it suitable for low-temperature industrial use?

Yes. The device is specified for an operating temperature range down to -40 ??C and up to +85 ??C, making it suitable for many industrial and outdoor applications with moderate thermal demands.
