FAQ

What core does it use?

It uses a 16-bit RISC CPU optimized for code density and low-power operation. This core is common in MSP430 value-line parts and supports efficient arithmetic and control flow for tight embedded code.

What is the ADC capability?

The device offers a 10-bit ADC with multiple input channels. That ADC enables direct interfacing to sensors and reduces the need for external conversion ICs in measurement applications.

Which serial interfaces are available?

It includes a USI module that can be configured for UART and SPI operation. That flexibility lets engineers implement simple serial links or connect to SPI peripherals with minimal external components.

How does it save power?

Multiple low-power modes let the MCU drop to microamp-range currents during idle periods. Combined with a low-voltage operating window, this reduces average power compared with many mainstream microcontrollers.

Is it suitable for industrial use?

Yes. The device is rated for -40 ??C to +85 ??C and comes in a 16-pin industrial package. These characteristics suit sensor interfaces and control electronics used in industrial settings.
