USB2 controller hubsMicrochip Technology Inc. announced seven new UCH2 ICs across three families that are said to be the the first to provide programmability, enabling the developers of PCs and mobile devices to configure their designs without external memory. These UCH2s support both USB2 and USB High Speed Interchip (HSIC) connectivity, help maximize battery life via low-power modes such as Link Power Management (LPM), and offer the ability to replace wall chargers with advanced battery charging modes, such as BC1.2, Apple, SE1 and China charging. For applications that need to communicate over multiple protocols, these UCH2s feature direct I/O bridging to I2C, SPI, UART and general-purpose I/O. They also have the flexibility to support the behaviors of multiple operating systems, such as vendor-specific messaging and FlexConnect for simple port reversals. Microchip’s new UCH2s integrate “Quad Page” configuration OTP Flash memory, which reserves space for interoperability and other customizations by the designer, including four separate configuration opportunities.
