The CY7C65210-24LTXI is an integrated USB 2.0 application-specific integrated circuit (ASIC) controller, designed to provide a cost-effective solution for USB 2.0 applications such as keyboards, trackballs and touchscreens. It is a member of Cypress Semiconductor\'s USB 2.0 family of interface controllers.

The CY7C65210-24LTXI provides a low-power, highly integrated, low-cost solution for USB 2.0 enabled systems. It supports up to four endpoints, is I²C and SPI compatible, and is capable of operating from a single 2-wire serial interface. The CY7C65210-24LTXI is also compliant with the USB 2.0 power-management specification, which allows it to quickly detect and respond to device wakeup events.

The CY7C65210-24LTXI offers a wide range of features and functions including an integrated USB 2.0 hub with four downstream ports, an integrated protocol engine, multiple clock domains, and DMA (direct memory access) support for data movement directly to and from host memory. It supports peak throughput rates of up to 480 Mbps and is compliant with the USB 2.0 specification. The integrated hub supports low, full, or high speed downstream ports, providing flexibility in system design and application.

The integrated protocol engine of the CY7C65210-24LTXI contains an embedded logical address, which allows it to autonomously access data through USB, without needing any external intervention. The protocol engine interprets the USB commands, performs the necessary protocol functions, and generates response packets to the host. It also provides buffering and control of data transactions at the endpoint level, allowing for seamless integration with external hardware.

The CY7C65210-24LTXI supports multiple clock domains and modern communication protocols, including an integrated I²C, SPI and MII interface. It supports data transmission and reception through serial peripheral or USB interfaces, making it ideal for applications that require high bandwidth transfer of data. The low power operation of the CY7C65210-24LTXI also makes it suitable for battery-powered devices.

The CY7C65210-24LTXI also provides an integrated DMA controller, allowing the processor to perform data transfers from system memory to the USB interfaces. DMA supports direct data movement from a system address to the various functions supported by the CY7C65210-24LTXI. This eliminates the need for CPU intervention, resulting in significant performance improvements.

The CY7C65210-24LTXI is designed to provide an ideal solution for a wide range of USB based applications. This cost-effective controller is highly integrated and provides plug-and-play operation, integrated USB 2.0 hubs, support for multiple clock domains, high throughput data transfers, and low power consumption.
