USB253x/USB46x4/USB3x13 Embedded Testing Modes
The Microchip USB253x/USB46x4/USB3x13 product lines are a family of feature-rich, low-power USB 2.0 hubs optimized for use in portable devices or embedded systems where high performance and minimal BOM costs are critical design requirements. The SMBus slave interface is a 2-pin protocol which can be used to customize the functionality of this family of USB hubs. The System on Chip (SoC) can use this interface to control the digital and USB lines for testing, configure custom functionality, and load custom firmware to unlock the various features of the embedded processor. Among these features is a USB compliance test mode designed to facilitate USB compliance testing when a USB253x/USB46x4/USB3x13 hub is applied within an embedded system.
