Introduction to USB

Universal serial bus (USB) was designed to standardize

the connection of the computer peripherals, such as

keyboards, mice, printers, pen drives, hard disks, and

portable media players, both to communicate and supply

power needed for them. USB is the most common

connectivity solution for PCs and consumer devices today.

Plug and play, easy to use and simple to implement, USB

continues to gain traction in new applications and market

segments. Coming to the history of the USB

specifications, the first version of the specification,

USB 1.0 was released in 1996. This version of

specification defines two transfer speeds to address the

different types of devices available until then. 1.5 Mbps

(low-speed) is to address the low speed devices like

keyboard and joysticks, 12 Mbps (full-speed) is to address

the devices like disk drives. USB 2.0 specification was

released in 2000 and it allows the maximum signaling rate

of 480 Mbps (high-speed), which is 40 times to the

signaling rate of full-speed. USB 3.0 specification was

released in 2008 and it allows the maximum signaling rate

of 5 Gbps (Superspeed), which is 10 times to the signaling

rate of high-speed.

Cypress FX2LP is a USB 2.0 peripheral controller and the

following sections talk about the overview of USB 2.0,

features of FX2LP, hardware, software and firmware

resource that are available for FX2LP.

Cypress offers a wide range of USB products including

low-speed, full-speed, and Superspeed devices. Refer to

the overview of the USB product portfolio on Cypress

website.

Getting Started with FX2LP™ USB 2.0 Overview Signaling rates supported by USB 2.0: The USB 2.0 transfers signal and power over a four wire cable and the supported data rates are:    Series “A” connector is used to connect the upstream towards the host and Series “B” connector is used to connect the downstream towards the devices. Standard Series “B” connector is defined for relatively large and stationary devices like hard drives, printers.

Getting Started with FX2LP™ Introduction to FX2LP EZ-USB FX2LP (CY7C68013A/14A/15A/16A) is a programmable, low-power USB 2.0 USB peripheral controller. The FX2LP chipset integrates the USB 2.0 transceiver, serial interface engine (SIE), an enhanced 8051 microcontroller, and a programmable peripheral interface in a single chip. Using this, you can create a wide range of cost-effective solutions with superior time-to-market.

Getting Started with FX2LP™ This FX2LP-DVK can be used as the debugging platform for FX2LP. The on-board EEPROM can store different configuration options for FX2LP. Note Since this development kit is for EZ-USB, which is a product family name that includes both FX2LP and FX1, the support collaterals in the DVK are divided into separate folders for FX1-based designs (FX1) and for FX2LP-based designs (FX2LP). When creating a USB 2.

Getting Started with FX2LP™ The snapshot of the CyControl is shown in the following figure: Figure 4. CyControl C yp r e s s G P I F D e s i g n e r The general programmable interface (GPIF) is an extremely flexible parallel interface, which can be programmed to act as a glueless interface, for connecting many types of external peripherals to EZ-USB FX2LP. The programmed GPIF is powerful enough to directly implement protocols such as ATAPI, EPP parallel port, Utopia, and so on.

Getting Started with FX2LP™ The snapshot of the GPIF Designer is shown in the following figure: Figure 5. GPIF Designer Windows Driver Frameworks (WDF) for Windows XP with SP2. The WinUSB architecture consists of a kernel-mode driver (Winusb.sys) and a user-mode dynamic link library (Winusb.dll) that exposes WinUSB functions. By using these functions, you can manage USB devices with usermode software. Winusb.sys is supported on Windows XP/Vista/7/8.
