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

External Memory Interface

EZ-Host provides a robust interface to a wide variety of

external memory arrays. All available external memory array

locations can contain either code or data. The CY16 RISC

processor directly addresses a flat memory space from

0x0000 to 0xFFFF.
