FAQ

What is the CPU architecture?

The device uses a 16-bit MSP430 RISC architecture. That architecture focuses on reduced instruction count and low-power operation, which cuts code execution time and lowers active current compared with many legacy 8-bit designs.

What supply voltage does it need?

It operates across a low-voltage range from 1.8 V up to 3.6 V. This allows direct connection to typical single-cell lithium or standard 3.3 V systems without additional regulators in many designs.

Does it include an ADC?

Yes, a 10-bit analog-to-digital converter is integrated on-chip. The ADC enables direct measurement of analog sensors, reducing external components and simplifying board layout for precision sensing tasks.

Which serial protocols are supported?

The Universal Serial Interface (USI) supports flexible serial modes, including UART-style, I2C and SPI-like communications. That flexibility helps interface multiple sensor types and peripheral devices with one peripheral block.

Is it suited for battery-powered products?

Yes, its multiple low-power modes and low active current profile make it well suited to battery-powered and energy-harvesting devices, extending operational life compared with many higher-power microcontrollers.
