TAS1020B Firmware Development Kit 1.0

TAS1020B Firmware Development Kit by Texas Instruments (TI)

The TAS1020B Firmware Development Kit is a complete software toolkit for building, customizing, and validating firmware for TI’s TAS1020B USB audio streaming controller. Centered around an 8052-based architecture, the kit streamlines development of class‑compliant USB audio devices and accelerates time to market for products such as USB DACs, audio interfaces, headsets, and docking stations.

Key capabilities

• Reference firmware for USB Audio Class (UAC1) devices, including isochronous audio streaming over full‑speed USB
• Example implementations for device control (HID/media keys, volume/mute), endpoint configuration, and descriptor customization
• I2S interface support to external DAC/ADC codecs, with sample code to adapt data paths and clocking
• Boot and update flows using on‑chip ROM bootloader, with host utilities for in‑system firmware download and EEPROM programming
• Proven USB descriptors and request handling to ease compliance and interoperability

What’s included

• Source code and sample projects tailored for the TAS1020B
• Build files targeting industry‑standard 8051/8052 toolchains (e.g., Keil C51)
• Prebuilt images and example USB descriptors for quick bring‑up
• PC‑side utilities for firmware download, testing, and basic audio/control verification
• Documentation: developer’s guide, API references, porting notes, and application examples

Benefits

• Reduces integration risk with production‑tested reference implementations
• Shortens development cycles through ready‑to‑use code and tools
• Eases customization of audio endpoints, controls, and device identity to fit specific product requirements

Typical applications

• External USB DACs and headphone amplifiers
• USB microphones and headsets
• Stereo audio interfaces and docking stations

Notes

• Requires a compatible 8051/8052 toolchain for building firmware
• Designed for full‑speed USB audio (USB Audio Class 1); host driver needs may vary by operating system
