SL811HS | Cypress Semiconductor


SL811HS is an embedded Full Speed USB host/slave controller. SL811HS incorporates USB interface functionality with internal full- or low-speed transceivers. When in host mode, SL811HS is the master and controls the USB bus and the devices that are connected to it. In peripheral mode, the SL811HS can operate as a full- or low-speed device. In addition, SL811HS can communicate with microprocessors, DSPs, and with various buses such as ISA, PCMCIA.
