نظرة عامة على المنتج
The Microchip USB2412-DZK is a low-power, single Transaction Translator (STT) USB 2.0 Hi-Speed hub controller with two downstream ports in a 28-pin QFN (5×5 mm) package. Designed for embedded USB applications, it supports low-speed, full-speed, and high-speed downstream devices. The device features fully integrated USB termination and pull-up/pull-down resistors, an on-chip 24MHz crystal driver, built-in default configuration requiring no external components, and 4kV HBM ESD protection on all pins. It operates from a single 3.3V supply with internal 1.2V regulators over the commercial temperature range of 0°C to +70°C.
