FAQ

What is the core architecture?

The MCU uses a 16?bit RISC CPU core common to the MSP430 family. This architecture yields higher data width than typical 8?bit parts and enables compact code and efficient arithmetic for control and sensing tasks.

Does it support serial protocols?

Yes. The device includes serial modules that support UART and SPI and can be used for I2C communications. These on?chip interfaces reduce external transceivers and simplify system integration.

What analog functions are available?

Integrated analog features include a 10?bit ADC and an analog comparator. These allow direct connection of many sensors and reduce the need for external ADC chips in measurement applications.

What voltage range is required?

The part operates from a low supply range suitable for battery systems. It supports typical embedded voltages and includes brown?out and reset functions for safe operation across supply variations.

How does it handle low?power operation?

Multiple low?power modes let the CPU sleep while peripherals like timers or serial interfaces remain active as needed. This approach minimizes average current draw and extends battery life in intermittent?activity systems.
