EM3586-IRT

RF Transceiver ICS Overview

The EM3586-IRT is a Zigbee and IEEE 802.15.4 System-on-Chip (SoC) from Silicon Labs, integrating an ARM Cortex-M3 core with RF transceiver capabilities. It operates in the 2.4 GHz ISM band with O-QPSK modulation. Key specifications include 512 KB of flash memory and 32 KB of RAM. The device supports a maximum data rate of 5 Mbps and delivers an output power of 8 dBm. It features a sensitivity of -100 dBm and operates on a supply voltage range of 1.18V to 1.9V for specific logic levels, or 2.1V to 3.6V generally. Current consumption is 28 mA during reception and varies during transmission.

RF Transceiver ICS Procurement Notes

Verify the specific suffix 'IRT' against official Silicon Labs documentation to confirm package type and temperature grade. Confirm availability status as some EM358x variants may be marked as Not Recommended for New Designs (NRND). Ensure compatibility with required operating voltage ranges specified in the datasheet before procurement.

RF Transceiver ICS Selection Notes

Select this component for applications requiring integrated MCU and RF in a compact form factor. Consider the 5 Mbps data rate limit compared to higher-speed variants if throughput is critical. Verify that the 8 dBm output power meets link budget requirements for the intended deployment environment.

RF Transceiver ICS Part Context

This part belongs to the Silicon Labs EM358x family of Zigbee SoCs. These devices are designed to simplify the development of wireless IoT solutions by combining processing and communication in a single chip. The EM358 series is widely used in residential and commercial automation due to its robust protocol support and low power characteristics.

RF Transceiver ICS Replacement Considerations

Check for EM3586-RT or EM3586-RTR for pin-compatible alternatives with different packaging. Verify if newer generations like EFR32MG series offer backward compatibility or improved performance metrics.
