eKA8566A

USB Audio Controller

1 General Description

The eKA8566A is a USB digital audio controller with audio data processing that

supports 16-bit 2-channel format at 48kHz, 44.1kHz, 32kHz or 8kHz sampling rate.

2

The device has an integrated USB transceiver, USB core, MCU, DAC, ADC, and I S

Input/Output. It can handle a high-level USB protocol, and manages user interface via

general I/O pins.
