The USB2514B-AEZC is a versatile and power-efficient USB 2.0 hub Controller IC. Leveraging Microchip's innovative MultiTRAK™ technology that delivers industry-leading data throughput in mixed-speed USB environments, the USB2514B-AEZC is an USB port expansion solution for applications that demand ultra low power and a small footprint without compromising on performance. Well-suited for consumer and mobile applications, all members of the USB2514B-AEZC family are available in a space-saving package. The common 36-pin package shared among the 2/3/4 port hub controller measures only 6x6 mm and provides an ultra small footprint for space-constrained designs while allowing scalable port expansion from two to four ports.
