USB3503数据手册集成电路（IC）的控制器规格书PDF

描述 Description

As portable devices continue to add more features and the system architecture becomes more complex, it is necessary to have more than one USB port to manage communications with internal and external peripheral devices. Microchip's low-power USB3503 offers three downstream ports and is specifically designed for portable embedded applications where more than one USB port is required. The USB3503 attaches to an upstream port via HSIC and supports Low, Full and Hi-Speed downstream devices on all enabled downstream ports. The package size has been minimized to save valuable PCB space, making the device well-suited for portable, battery-powered embedded systems where power consumption, reduced BOM cost and Battery Charger (BC) detection capabilities are critical design requirements.The USB3503 is the industry's first HSIC-based USB 2.0 hub controller designed specifically for portable consumer electronics products such as smartphones, tablets and e-readers. Designed to deliver the low-power and ultra-small footprint that portable product designers demand, the USB3503 also delivers robust USB performance proven through multiple generations of Microchip USB 2.0 hub controller products.The USB3503 integrates the latest USB-IF Battery Charging 1.1 specification with Microchip's RapidCharge Anywhere™ functionality that dramatically reduces the time required for battery charging, while its flexible power regulators facilitate simple design into battery-powered devices. Microchip's complimentary and confidential MicroCHECK design review service, which offers insight from the initial concept to the final PCB layout, is available to customers who are using our products in their projects. You can confidently submit your design materials in a secure and private setting, and our expert engineers will provide individualized feedback to enhance your design. MicroCHECK design review service is subject to Microchip's Program Terms and Conditions and requires a myMicrochip account.
