FAQ

What memory type is used?

This MCU uses FRAM (ferroelectric RAM) as its nonvolatile memory. FRAM offers fast writes, low energy per write, and high endurance compared with flash memory.

What is the core architecture?

The part is based on a 16-bit RISC core. This architecture provides compact code density and efficient control performance for embedded tasks and low-power operation.

What supply voltages are supported?

Designed for 1.8 V to 3.6 V operation. This range supports single-cell battery systems and many common industrial power rails without external regulators in many designs.

What temperature range is guaranteed?

The device is specified for industrial temperature applications, operating typically from -40 ??C up to +85 ??C to meet common industrial reliability requirements.

How does FRAM benefit designs?

FRAM enables faster nonvolatile writes and far greater write endurance than flash. That reduces energy per write and extends lifetime for frequent-logging or calibration tasks.
