5 / 112 page CY7C67300 Document Number: 38-08015 Rev. *L Page 5 of 112 USB Features ■ USB 2.0-compliant for full and low speed ■ Up to four downstream USB host ports ■ Up to two upstream USB peripheral ports ■ Configurable endpoint buffers (pointer and length), must reside in internal RAM ■ Up to eight available peripheral endpoints (one control endpoint) ■ Supports control, interrupt, bulk, and isochronous transfers ■ Internal DMA channels for each endpoint ■ Internal pull up and pull down resistors ■ Internal series termination resistors on USB data lines USB Pins OTG Interface EZ-Host has one USB port that is compatible with the USB On-The-Go supplement to the USB 2.0 specification. The USB OTG port has a various hardware features to support Session Request Protocol (SRP) and Host Negotiation Protocol (HNP). OTG is only supported on USB PORT 1A. OTG Features ■ Internal charge pump to supply and control VBUS ■ VBUS valid status (above 4.4V) ■ VBUS status for 2.4V< VBUS <0.8V ■ ID pin status ■ Switchable 2K ohm internal discharge resistor on VBUS ■ Switchable 500 ohm internal pull up resistor on VBUS ■ Individually switchable internal pull up and pull down resistors on the USB data lines OTG Pins 2 Hosts + 1 Peripheral Host Host Peripheral – 2 Hosts + 1 Peripheral Host Host – Peripheral 2 Hosts + 1 Peripheral Peripheral – Host Host 2 Hosts + 1 Peripheral – Peripheral Host Host 1 Host + 1 Peripheral Host – Peripheral – 1 Host + 1 Peripheral Host – – Peripheral 1 Host + 1 Peripheral – Host – Peripheral 1 Host + 1 Peripheral – Host Peripheral – 1 Host + 1 Peripheral Peripheral – Host – 1 Host + 1 Peripheral Peripheral – – Host 1 Host + 1 Peripheral – Peripheral – Host 1 Host + 1 Peripheral – Peripheral Host – 2 Peripherals Peripheral – Peripheral – 2 Peripherals Peripheral – – Peripheral 2 Peripherals – Peripheral – Peripheral 2 Peripherals – Peripheral Peripheral – 1 Peripheral Any Port Table 3.
