Reference Manual

ReadyBoard 620

Note:

The shaded area denotes power or ground. Signals are listed in the following order: RS232 
followed by RS485/RS422. The signals marked with * = Negative true logic. 

USB Interfaces 

The I/O Hub (CS5536) provides the USB solution for both legacy OHCI controllers and EHCI controller 

(USB 2.0) support. The I/O Hub (Southbridge) contains port-routing logic that determines which controller 
(OHCI or EHCI) handles the USB data signals. The PC style (or Standard) connector (J13A/B) provides two 

of the four USB ports (USB0 and USB1). The other two USB ports share a single 10-pin header (J17A/B) on 
the board. 

USB 2.0 Support

The I/O Hub contains an Enhanced Host Controller Interface (EHCI) compliant host controller, which 

supports up to 4 high-speed USB 2.0 Specification compliant root ports. The higher speed USB 2.0 

specification allows data transfers up to 480 Mbps using the same pins as the 4 Full-speed/Low-speed USB 
OHCI ports. The I/O Hub port-routing logic determines which of the controllers (OHCI or EHCI) processes 

the USB signals. The following list provides some of the ReadyBoard 620’s EHCI features.

•

One EHCI host controller for all four USB ports on connectors (J17A/B, and/or J13A/B)

•

Support for USB v2.0 Specification

•

Over-current fuses, located on the board, where USB0 and USB1 share a single fuse (F3) and USB2 and 
USB3 share a single fuse (F2). 

Legacy USB Support 

The I/O Hub supports two USB Open Host Controller Interfaces (OHCI) and each Host Controller includes 
a root hub with two USB ports each, for a total of 4 USB ports. The USB Legacy features implemented on 

the USB ports include the following:

•

One root hub and two USB ports on connector (J17A/B)

•

One root hub and two USB ports on connector (J13A/B)

•

Supports USB v.1.1 OHCI with integrated physical layer transceivers

•

Supports improved arbitration latency for OHCI controllers 

•

OHCI controllers support Analog Front End (AFE) embedded cell instead of USB I/O buffers to allow 
for USB high-speed signaling rates

•

Over-current fuses, located on the board, are used on all four USB ports
