CY7C68016A-56LTXC application field and working principle

The CY7C68016A-56LTXC is a highly integrated, low voltage USB peripheral controller designed for easy integration into many different application fields. It offers a full-speed 12 Mbps USB Iface, device specific instructions and offloads the host system processor of a variety of tasks. CY7C68016A-56LTXC has been designed as a secure, flexible and cost effective solution for consumers and commercial applications.

Application Field

CY7C68016A-56LTXC is targeted at a variety of applications and is suitable for designing a USB interface into products such as digital cameras, calculators, scanners and other devices. It helps to offload the host of tasks associated with the interface, including USB enumeration and data transfers, simplifying the design and providing a seamless and reliable interface.

Working Principle

The CY7C68016A-56LTXC operates on a USB peripheral architecture with a 12 kbps USB 1.1 (low-speed) or full-speed data rate, 4096 bytes of Code RAM, 512 bytes of EEPROM, 128 bytes of EEPROM, 512 bytes of SRAM and 16 kbytes of 8-bit programmable external data memory. The data rate can be programmed and there are many features to provide a secure and reliable USB interface, such as hardware encryption/decryption, CRC, hardware protection, firmware update support and HID support. Information is exchanged between the device and the host, first a SETUP Packet (GET_VAR, GET_DIB, etc.). The controller has a number of dedicated 10-bit inputs or 10-bit outputs which can be used for custom compatible data transfer functions and also supports dedicated commands such as GET_CLASS and SET_DIB for debugging purposes.The controller also supports a range of USB specific features such as suspend and resume, isochronous transfers, power management, device configuration and device descriptors, as well as hardware and software protocol support. Additionally, vendor-specific control registers and command decoders are accessible to customize communication between the host and the device.The CY7C68016A-56LTXC USB controller also supports up to 8 endpoint USB transfers, allowing simultaneous transfers to and from the device. Integral support is provided for transfer speeds up to 12 Mbps as well as 128 byte FIFOs and dual porting. This provides scalability in the supported applications and greater flexibility in design.To support multiple USB applications and topologies, the CY7C68016A-56LTXC controller supports two USB ports for high speed, one port and two ports for full speed and four ports for low speed with support for both USB1.1 and USB2.0Compliant. A dedicated I/O port designed to communicate with vendor specific devices adds great flexibility to the device.The CY7C68016A-56LTXC also features integrated power and clock management features, providing features such as power on/off and deep sleep cyclical clock gating. This helps to increase system functionality, stability and reduce power consumption significantly.In addition to the above listed features, the CY7C68016A-56LTXC controller is highly programmable and supports a variety of operating modes. Some of these includes; multiple processor interfaces, CPU instruction control, low-power writeback and watchdog timer. These features provide easy to use tools to manipulate and control the device parameters.In conclusion, multi-featured CY7C68016A-56LTXC USB peripheral controller is a powerful and cost effective device that provides a reliable solution to many consumer and commercial applications. This device offers a low voltage operation, high speed operation, isochronous transfers, power management, device configuration and device descriptors, along with vendor specific control registers, integrated power and clock management features, and integrated support for up to 8 endpoints.
