MSP430G2353IPW20 Technical Specifications

MSP430G2353IPW20 Key Features

• 16-bit core for faster integer math and simpler code vs many 8-bit MCUs.
• On-chip flash reduces BOM and enables in-system firmware updates.
• Low-voltage operation supports 1.8?C3.6 V, improving compatibility with single-cell Li-ion or two-cell NiMH systems.
• Integrated 10-bit ADC for direct sensor interfacing without external converters.
• UART/SPI via USCI simplifies communication with modems, sensors, and other MCUs.
• Multiple low-power modes extend battery life and lower average system power vs always-on designs.
• Compact 20-pin package enables smaller board area compared to DIP or larger LQFP alternatives.

Typical Applications

• Battery-powered sensor nodes where the MCU must sample analog sensors, process data and transmit serialized packets while minimizing average current draw over long duty cycles.
• Portable medical devices that require 10-bit analog measurements and low standby power for longer operation between charges or battery swaps.
• Consumer handheld controllers where a small 20-pin footprint, multiple GPIO and serial interfaces are needed for buttons, LEDs and external radios.
• Industrial monitoring modules that use a single MCU to perform timing, ADC reads and UART communication in compact enclosures with extended temperature range.

MSP430G2353IPW20 Advantages vs Typical Alternatives

The device combines a 16-bit core and ultra-low-power sleep modes to deliver more processing per milliampere than many 8-bit parts. On-chip flash and a 10-bit ADC reduce external components and board cost versus solutions needing separate ADC or memory. The 20-pin package balances pin count and size, offering more I/O and peripherals than smaller SOIC devices while occupying less PCB area than larger LQFP alternatives.

FAQ

What is the core architecture?

The MCU uses a 16-bit RISC architecture optimized for energy efficiency and deterministic interrupt response. This core delivers simpler arithmetic and fewer instructions compared with 8-bit cores for many control tasks.

What supply voltages are supported?

Designed for low-voltage systems, it operates from a typical 1.8 V to 3.6 V range. This makes it suitable for single-cell lithium systems and common low-voltage logic domains.

How many GPIO and peripherals are available?

The 20-pin package exposes multiple general-purpose I/O pins along with built-in peripherals including a 16-bit timer and a universal serial communication interface that supports UART and SPI functions.

Is analog input supported?

Yes. A 10-bit analog-to-digital converter is integrated for direct sensor measurements, which reduces the need for external ADC components in many designs.

What development resources are available?

Texas Instruments provides datasheets, application notes, reference designs and IDE support. Starter kits and example firmware are commonly available to speed up board bring-up and validation.
