RF Transceiver ICS Procurement Notes

Verify the specific suffix 'C0R' against the official datasheet to confirm package type and tape-and-reel configuration. Confirm that the component status is appropriate for your design lifecycle, as older Blue Gecko variants may be subject to obsolescence notices. Ensure compatibility with existing firmware libraries for Bluetooth v4.0 support.

RF Transceiver ICS Selection Notes

Select this model when Bluetooth v4.0 compliance is required rather than newer BLE versions. It is suitable for applications needing moderate processing power via the Cortex-M4 core. Consider the 256 kB flash capacity for code storage needs. Evaluate the QFN-32 footprint against PCB space constraints compared to larger packages like QFN-48.

RF Transceiver ICS Part Context

This part belongs to the Blue Gecko family, designed for cost-effective Bluetooth solutions. It shares architectural similarities with other MG1 and BG1 series chips but differs in radio specifications and package options. It serves as a foundational SoC for early-generation BLE products before the transition to BG2x series.

RF Transceiver ICS Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Check for direct pin-compatible upgrades within the same generation or consider migration to the BG2x series for enhanced performance and newer Bluetooth standards.
