FAQ

What is the core architecture?

The device uses a 16-bit RISC core optimized for low-power operation. This architecture provides better arithmetic and control performance than typical 8-bit cores while keeping power and code size low.

What ADC resolution is available?

The integrated ADC is 10-bit with multiple input channels. That resolution suits many sensor and metering tasks without adding an external converter, saving board space and cost.

Which serial protocols are supported?

The on-chip Universal Serial Interface supports UART, SPI and I2C modes. This gives flexible options for host links, sensor buses and peripheral ICs using common serial standards.

What are the power rails and limits?

The MCU accepts a supply between 1.8 V and 3.6 V. This range supports most coin-cell and single-cell Li-ion systems and enables low-voltage battery operation with stable performance.

What temperature range does it support?

The device is specified for industrial operation from -40 ??C to +85 ??C. This allows deployment in harsher environments compared with commercial-only temperature parts.
