DA14581-00AT1

RF Transceiver ICS Overview

The DA14581-00AT1 is a Bluetooth Low Energy 4.2 System-on-Chip (SoC) optimized for A4WP and HCI applications. It features an ARM Cortex-M0 core operating at up to 48 MHz with 32 kB program memory and 42 kB SRAM. The device integrates a 2.4 GHz transceiver with 0 dBm output power and -93 dBm sensitivity. It operates on a single 3.3 V supply, drawing 3.4 mA during transmission and 3.7 mA during reception. The component is housed in a QFN-40 package measuring 5 mm x 5 mm x 0.9 mm, offering 24 GPIOs.

RF Transceiver ICS Feature Summary

• Integrated radio transceiver and baseband processor compliant with Bluetooth 4.2 standards
• Dedicated ROM storing qualified protocol stack including L2CAP, SM, ATT, GATT, and GAP
• Flexible memory architecture supporting Over-the-Air (OTA) updates for profiles and custom code
• Hardware implementation of Link Layer with interface controllers for enhanced connectivity

RF Transceiver ICS Applications

• Power Receiving Unit (PRU) for Alliance for Wireless Power (A4WP)
• Human-Computer Interaction (HCI) devices
• Proximity sensors and beacons
• Health and fitness trackers

RF Transceiver ICS Procurement Notes

Verify the specific suffix AT1 against official Renesas documentation to confirm pinout and package dimensions. Confirm RoHS compliance status via the manufacturer's current datasheet. Check lifecycle status as previous models may be marked Not Recommended for New Designs (NRND). Ensure compatibility with existing antenna designs given the integrated RF I/O requirements.

RF Transceiver ICS Selection Notes

Select this SoC for applications requiring ultra-low power consumption and small form factors. The integrated nature reduces external component count compared to discrete solutions. Consider the 3.3 V supply constraint and verify that the 24 GPIOs meet interface requirements. Evaluate OTA update capabilities if field firmware upgrades are necessary for the target application.

RF Transceiver ICS Part Context

This component belongs to the SmartBond family of Bluetooth Low Energy SoCs from Renesas Electronics Corporation. It is based on the DA14580 architecture but offers optimizations such as reduced boot time. The series targets battery-powered IoT devices where size, cost, and power efficiency are critical design constraints.

RF Transceiver ICS Replacement Considerations

The DA14585 and DA14586 are listed as alternative products within the SmartBond portfolio. Verify pin compatibility and software migration efforts before substitution. Note that newer models may support Bluetooth 5.0 specifications instead of 4.2.
