The CY7C64225-28PVXCT is a low-power, high-speed, quad-channel universal serial bus (USB) transceiver. It is specifically designed to provide a low-cost, low-power solution for USB peripherals such as keyboards, mice, and printers. The CY7C64225-28PVXCT is an 8-bit, register-based programmable logic device (PLD) which can be configured to interface with many different types of digital signals, including RS-232, SPI, I2C and UART. The device also has an embedded on-chip voltage regulator, which allows it to operate from a single supply voltage of 3.3V.

The CY7C64225-28PVXCT is mainly used as an interface controller in embedded products. It acts as a controller between the host system and the USB peripherals. It provides the host with a means of communicating with the USB devices over a USB connection. The controller can also be used to provide a means of communication between a host system and an external I/O bus system, such as a SPI bus or I2C bus.

The CY7C64225-28PVXCT supports two forms of data transfer, namely, control and bulk transfers. Control transfers are used for communication between the host and the USB device, while bulk transfers are used to transfer large amounts of data over a USB connection. The controller also supports data rates of up to 12 Mbps, and can support up to sixteen endpoints.

The CY7C64225-28PVXCT uses the USB protocol for data transfer. The device supports the USB 2.0 standard and the USB On-The-Go (OTG) specification. It also supports multiple transfer modes, including interrupt transfers, isochronous transfers, and isochronous pipelining transfers. The controller also supports built-in power management, allowing the device to enter low-power states when idle.

The CY7C64225-28PVXCT incorporates an 8-bit microprocessor core, which provides programmable signal handling abilities. The microprocessor core is powered by an external system clock, which allows it to receive data at higher speeds. The controller can support multiple external interrupt sources, allowing it to receive interrupts from external devices embedded in the system.

The CY7C64225-28PVXCT is housed in a 64-pin LQFP package and is supported by a variety of development tools. The controller also comes with on-chip program and data memories, allowing it to be reprogrammed using the Flash memory. The controller is available in two temperature ranges, industrial (-40° to +85°C) and commercial (0° to +70°C). Electrical specifications are also provided to allow designers to select the appropriate controller for their application.

In summary, the CY7C64225-28PVXCT is a low-cost, high-speed, and low-power, quad-channel interface controller specifically designed for USB peripherals. It supports multiple data transfer modes, supports power management, and has an 8-bit microprocessor core. It is housed in a 64-pin LQFP package and is supported by a variety of development tools.
