Description

The TAS1020A integrated circuit (IC) is a universal serial bus (USB) peripheral interface device designed specifically for applications that require isochronous data streaming. Applications include digital speakers, which require the streaming of digital audio data between the host PC and the speaker system via the USB connection. The TAS1020A device is fully compatible with the USB Specification Version 1.1 and the USB Audio Class Specification.

The TAS1020A uses a standard 8052 microcontroller unit (MCU) core with on-chip memory. The MCU memory includes 8K bytes of program memory ROM that contains a boot loader program. At initialization, the boot loader program downloads the application program code to a 6,016-byte RAM from either the host PC or a nonvolatile memory on the printed-circuit board (PCB).
