• On-chip debug circuitry for non-intrusive in-system debugging without external emulators
• Flexible interrupt handling and power management modes including idle and stop

Applications

• USB communication devices
• Data acquisition systems
• Portable instruments
• Sensor interface circuits

Procurement Notes

Verify the specific suffix 'GMR' against official documentation to confirm reel packaging and tape-and-reel specifications. Ensure the selected variant matches the required operating temperature range and voltage supply constraints for the target application environment.

Selection Notes

Select this component when a highly integrated solution combining USB connectivity with analog signal processing is required. The device offers footprint compatibility with other members of the C8051F38x family, facilitating design upgrades or changes in memory capacity while maintaining pinout consistency.

Part Context

This part belongs to the C8051F38x family of mixed-signal microcontrollers. These devices are designed as complete system-on-a-chip solutions, integrating essential peripherals such as oscillators, voltage regulators, and reset circuits to minimize external component count and simplify board layout.

Replacement Considerations

Check for end-of-life status on similar parts like the C8051F380-GQ. Consider EFM8BB series for new designs as the C8051F38x family may be marked not recommended for new designs.
