• On-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators
• Flexible General-Purpose I/O pins with 5 V tolerance and crossbar-enabled configuration

Applications

• Battery chargers
• Electronic toys and games
• Motor control systems
• Optical communications

Procurement Notes

Verify the specific suffix against the manufacturer's current documentation, as this component is marked Not Recommended for New Designs. Confirm package type and temperature grade requirements before ordering. Check for active replacement part numbers within the same family if long-term availability is required.

Selection Notes

Select this model when a low-cost 8-bit MCU with mixed-signal capabilities is needed. Ensure the application fits within the 2.2 V to 3.6 V supply range. Consider the 16-pin SOIC package constraints for pin count and physical layout. Verify that the 8 kB Flash and 512 Bytes RAM meet the program and data storage requirements.

Part Context

This part belongs to the C8051F85x/86x series of low-cost 8-bit MCUs. The family shares common architectural features such as the CIP-51 core and peripheral sets. Differences between models typically involve memory size, package options, and temperature ranges. This specific variant uses the -Gx commercial temperature grade and SOIC-16 packaging.

Replacement Considerations

Check for EFM8BB51F8G or similar newer Silicon Labs 8-bit MCU families. Verify pin compatibility and software migration paths if replacing with a different package or series.
