USB HUB WITH MICROCONTROLLER

The CY7C65113C device is a one-time programmable 8-bit microcontroller with a built-in 12-Mbps USB hub that supports up to four downstream ports. The microcontroller instruction set has been optimized specifically for USB operations, although the microcontrollers can be used for a variety of non-USB embedded applications.
