RF Transceiver ICS Procurement Notes

Verify component authenticity carefully as this part number is listed as End-of-Life by the manufacturer. Confirm that current inventory sources are authorized distributors or certified secondary market suppliers. Ensure the specific package variant matches design requirements due to potential legacy stock variations. Check RoHS compliance documentation explicitly before integration into new production runs.

RF Transceiver ICS Selection Notes

Select this component when a combined MCU and BLE radio solution is required within a single package. Consider the 1.8 V to 5.5 V operating range for flexible power domain designs. Evaluate the 24-channel ADC capability against sensor interface needs. Note the limited I/O count of 36 pins may constrain complex peripheral integration compared to larger packages.

RF Transceiver ICS Part Context

This device belongs to the PSoC BLE family, designed for compact wireless applications. It merges processing, memory, and RF functions to reduce bill-of-materials complexity. The QFN-56 package provides a small footprint suitable for space-constrained portable electronics. It represents a consolidated approach to Bluetooth-enabled embedded systems.

RF Transceiver ICS Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Due to the End-of-Life status, direct replacements may require redesigning the PCB layout and firmware architecture to accommodate different pinouts or memory configurations.
