Application Specific Microcontrollers datasheet and documents for DARR84-APK
Application Specific Microcontrollers Overview
The DARR84 is a highly-integrated wireless audio processor based on Microchip’s KleerNet technology. It supports tri-band operation at 2.4, 5.2, and 5.8 GHz with Wireless DNA technology to mitigate interference from Wi-Fi, Bluetooth, and microwave ovens. The device integrates a 16-bit HD stereo DAC with a headphone amplifier and a 16-bit mono ADC with a microphone amplifier. It features an integrated SRC for multiple sampling rates, bi-directional audio support, and an embedded 8052 MCU. Designed for battery-powered applications like AAA batteries or charging circuits, it offers low-latency transmission under 20 ms.
Application Specific Microcontrollers Feature Summary

Application Specific Microcontrollers Procurement Notes
Verify the specific revision suffix against the datasheet DS00001615A to ensure compatibility with required reference designs. Confirm that the supplier provides the complete component rather than a development kit. Check for moisture sensitivity labeling as the device requires proper handling during storage and assembly.
Application Specific Microcontrollers Selection Notes
Select the DARR84 when a solution requires multi-band flexibility and low-latency uncompressed audio without external DACs or ADCs. It is suitable for designs needing bi-directional voice communication and Dolby certification compliance. Ensure the application supports the required antenna diversity algorithms for robust link performance in multipath environments.
Application Specific Microcontrollers Part Context
The DARR84 extends Microchip’s KleerNet interoperability, deriving its core from the DARR83 processor. It targets high-end audio devices by reducing overall solution costs through high integration. The device facilitates connectivity with other KleerNet-enabled consumer electronics, supporting open interoperability across brands.
Application Specific Microcontrollers Replacement Considerations
The DARR83 is identified as the predecessor model sharing the fundamental core. Verify pinout and feature parity if substituting, noting that the DARR84 adds tri-band support and higher integration compared to earlier iterations.
