RF Transceiver ICS Procurement Notes

Verify the specific suffix 'CR' indicates tape-and-reel packaging when sourcing components. Confirm that the part number matches the exact memory configuration of 1024 kB flash and 128 kB RAM. Ensure compatibility with the required operating temperature range of -40°C to +85°C for the intended application environment.

RF Transceiver ICS Selection Notes

Select this component for applications requiring low-power BLE connectivity with moderate code storage needs. The 0 dBm output power is suitable for short-range communications. Consider the QFN-48 package size for PCB layout constraints. Evaluate if the 40 MHz clock speed meets the processing requirements for the specific firmware implementation.

RF Transceiver ICS Part Context
