... In 1993, engineers from Compaq, Intel, Microsoft, and NEC gathered and jointly developed a peripherals interface for next-generation PCs. This led to their release of the first USB 1.0 specifications (standards) in 1996. USB 1.1 was released in 1998 and USB 2.0 was released in 2000. For many years, the RS-232C and printer ports served as the main interface for connecting peripherals ...

... The MB91F662 installed on this board is equipped with the Mini-Host function. 3. Signal lines USB cables are inexpensive to make, using only two signal lines and two power lines. The two signal lines carry 3.3 V differential signals (D+ and D-). The two power lines are labeled Vbus (5V), and GND. Connected devices can draw up to 500 mA of power, allowing manufacturers to develop devices that do not require external power supplies ...
Page 58
... Plug Each end of the USB has a plug with a different shape. One end is called the A plug, the other the B plug. A smaller connector is used on embedded devices and is called a Mini-A plug and Mini-B plug, to distinguish from the standard plug size. The cable supplied with this board has an A plug and a Mini-B plug ...
Page 59
... A Full Speed device pulls up the D- signal line with a 1.5 kΩ (R2) resistor. (Transfer rate types will be discussed later.) After the USB device is connected, the host detects whether it is the D+ signal line or D- signal line that is pulled up, and selects its data transfer rate accordingly. ...
Page 60
... Transfer methods Several transfer methods are specified for the USB. Table 4.7-1 below summarizes the USB transfer methods. Isochronous transfer This is the most preferred transfer method for the USB. This transfer method has a guaranteed Typical bandwidth and is used application where real-time transfers ...
Page 61
... Each function and hub has several buffers for transferring data over the USB called endpoints. A full speed device can have endpoints, while a low speed device can have up to three. Each endpoint is defined with an endpoint number, transfer direction, transfer method, and maximum packet size ...
Page 62
... The USB device uses the descriptor to inform the host of its attributes. There are several types of descriptors that the host can request. In turn, the device returns information that describes itself to the host. The USB device is ready to be used by the host when it has been assigned an address and its configuration has been recognized. (Refer to Figure 6 below) Figure 4 ...
Page 63
... USB transmissions are managed by dividing time into frames that repeat every 1 ms, and allocating small portions of this transmission time to each device within each frame. The host starts a frame by sending the SOF packet every 1 ms. This is followed by a token packet sent from the host, which informs the device of the transfer type, device address, and end point. ...
Page 64
... The packets shown in Figure 4.9-3 are combined to form a frame for transferring over the USB. Each packet will be explained. All packets begin with a SYNC field. This is an 8-bit field used to synchronize the input data and local clock on the input circuit. The SYNC field is used only for synchronizing. The frame starting packet contains an SOF (Start of Frame) field after the SYNC field ...
