Description

The D720200AF1 uses a PCI Express Gen 2 system interface bus allowing system designers to easily add up to two USB3.0 SuperSpeed interfaces to systems containing the PCI Express bus interface. When connected to USB 3.0-compliant peripherals, the μPD720200A can transfer information at clock speeds of up to 5 Gbps. The μPD720200A and USB 3.0 standard are fully compliant and backward compatible with the previous USB2.0 Standard. The new USB 3.0 standard supports data transfer speeds of up to ten times faster than those of the previous-generation USB2.0 standard, enabling quick and efficient transfers of large amount of information.

S2R72V27 USB Controller

Description

The S2R72V27 is a USB host/device controller LSI that supports the USB 2.0 high-speed mode. A single USB port can be operated as a USB host or USB device depending on how control is switched. This LSI maintains high compatibility with the S2R72V17 but includes additional functions such as support for USB host isochronous transfers. This Device is also compatible with S2R72V27 at it’s function.

Features

1. Supports HS (480 Mbps), FS (12 Mbps), and LS (1.5 Mbps) transfer
2. Built-in pull-down resistor for downstream ports (no external circuit required)
3. Built-in HS termination (no external circuit required)
4. Supports control, bulk, interrupt, and isochronous transfers
5. Supports HS (480 Mbps) and FS (12 Mbps) transfer
6. Built-in FS/HS termination (no external circuit required)
7. VBUS 5V I/F (requires external protective circuit)
8. Supports control, bulk, interrupt, and isochronous transfers

The sequence of steps for turning the power supplies on and off are described below. This LSI cannot be operated with only the LVDD or CVDD power supplies turned on or off. The HVDD can be turned off if the LVDD or CVDD power supplies are on. The synchronous register cannot be accessed while HVDD is off, since the PLL does not operate. Also, the following restrictions apply to the sequence for turning the CVDD/HVDD I/O power supplies and LVDD internal power supply on or off. There are no restrictions on the sequence for turning the CVDD and HVDD power supplies on or off.
