Note the following details of the code protection feature on Microchip devices:
Microchip products meet the specification contained in their particular Microchip Data Sheet.
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions.
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
Microchip is willing to work with the customer who is concerned about the integrity of their code.
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act.

Chapter 1. Introduction

The OS8121X Slim Board Family is a powerful set of different demonstration boards that have been designed to showcase a variety of application-specific use cases, such as the operation of several audio instances.
Available demonstration boards are the:
OS81210 USB Application Boards (available as USB master or USB slave board)
OS81214 Slim Auxiliary I/O Board
OS81214 Slim Microphone Board
Figure 1-1 shows a powerful and low-cost example setup that uses Slim Boards; both

OS8121X Slim Board Family
The idea behind the Slim design pattern is to avoid an MCU running on all but one of the devices in the network. However, a controlling instance is needed to allow a wide variety of use cases. This instance is an OS81210 USB Application Board, which con­nects via USB to an MCU or SoC.

Chapter 2. OS81210 USB Application Boards

2.1 OVERVIEW

An OS81210 USB Application Board is available in two flavors: as USB master board and USB slave board. A USB slave board has per default the configuration interface disabled, which allows the configuration of INIC resources, such as ports and sockets from network side. The USB master board has per default the configuration interface enabled, which allows a locally attached EHC the configuration of INIC resources (con­figuration requests from network side are rejected). Both boards are identifiable by a Master or Slave sticker affixed on the top side of the board.
OS81210 USB Application Boards are used to interface a controlling instance to the network. In many cases this will be a single board computer or a laptop running Linux. The boards are used to configure any Slim Board on the network and to feed and receive audio streams to/from the network. If the MOST Linux Driver is used, a record or playback ALSA interface can be utilized for this purpose. An image of the board is shown in Figure 2-1.

2.3 FUNCTIONAL DESCRIPTION

Figure 2-2 gives an overview of the board’s main components.
FIGURE 2-2: BLOCK DIAGRAM
An OS81210 USB Application Board provides an electrical Physical Layer (ePHY) interface to the network. The electrical interface is implemented with passive front-end components [1]. If the board is connected with the Power Injector Box, the 12 V of the box are used to feed the on-board power supply, which provides 1.8 V INIC core supply and 3.3 V for INIC I/Os and other components. As long as the output voltage of the power supply is not stable, the INIC will be hold in reset.
The Configuration/Debug Header Connector is used to read, load or customize the INIC’s initial start-up configuration data.
DS60001523A-page 14  2017 Microchip Technology Inc.
The USB connector is used to connect the board to USB applications. For more infor­mation refer to the INIC Hardware Data Sheet [1]. If the Power Injector Box is not con­nected, the board can also be powered via the USB connector.
