NRF9E5-REEL

RF Transceiver ICS Overview

The NRF9E5-REEL is an RF system-on-chip from Nordic Semiconductor, integrating a transceiver and an 8051 microcontroller. It operates in ISM bands at 433 MHz, 868 MHz, and 915 MHz. The device supports GFSK modulation with a maximum data rate of 50 kbps. Key electrical parameters include a transmit power of 10 dBm, receiver sensitivity of -100 dBm, and a supply voltage range of 1.9 V to 3.6 V. Current consumption is specified as 12.5 mA during reception and 9 mA during transmission. It utilizes an SPI interface and is housed in a QFN-32 package.

RF Transceiver ICS Feature Summary

RF Transceiver ICS Procurement Notes

Verify the specific suffix against official documentation to confirm packaging type and functional variants. Ensure compatibility with the required operating voltage and frequency band for the target application. Cross-reference the datasheet for environmental ratings and interface specifications before integration.

RF Transceiver ICS Selection Notes

Select this component for designs requiring integrated MCU and RF functionality in a compact form factor. Consider the 8051 architecture constraints and the specific ISM band requirements. Evaluate the trade-off between the moderate data rate and the low power consumption profile suitable for battery-operated devices.

RF Transceiver ICS Part Context

This part belongs to the nRF9 series of wireless SoCs from Nordic Semiconductor. It represents an earlier generation of integrated RF solutions compared to modern nRF5 or nRF91 series products. The device is designed for cost-sensitive applications needing basic wireless connectivity without complex protocol stacks.

RF Transceiver ICS Replacement Considerations

Check for direct pin-compatible substitutes within the same family. Verify if newer generations offer improved performance or lower power while maintaining software compatibility.
