CY7C63803-SXC

Controllers Overview

The Infineon CY7C63803-SXC is a USB peripheral controller integrated circuit belonging to the CY7C638xx series. It supports USB 2.0 High Speed (HS) communication with a data rate of 1.5 Mb/s for low-speed operations. The device operates within a supply voltage range of 4 V to 5.5 V and draws a maximum operating current of 10 mA. Designed for surface mount applications, it is housed in an 8-pin SOIC package. The component functions as a dedicated interface between host systems and USB peripherals.

Controllers Feature Summary

• Integrated USB 2.0 compliant peripheral controller functionality
• Supports high-speed and low-speed data transfer modes
• Direct SPI interface capability for host connection

Controllers Applications

• USB peripheral control interfaces
• Low-speed USB device implementations
• Host-to-peripheral communication bridges

Controllers Procurement Notes

Verify the specific suffix designation against official documentation, as the provided model references the SXC variant while verified datasheets often cite SXCT. Confirm availability status, as this product line may be discontinued or subject to end-of-life notices. Ensure the selected package matches the required PCB footprint constraints before ordering.

Controllers Selection Notes

Select this component when a dedicated USB peripheral controller is required for low-speed data transmission. Verify that the 4V to 5.5V supply range aligns with the system power architecture. Consider the 8-pin SOIC package dimensions for layout compatibility. Evaluate if the integrated controller logic meets the specific protocol requirements of the target peripheral application.

Controllers Part Context

This part belongs to the Infineon CY7C638xx family of USB controllers. These devices are designed to simplify the integration of USB connectivity into embedded systems by handling the physical layer signaling and protocol management. The series typically offers compact solutions for low-cost USB peripheral designs.

Controllers Replacement Considerations

Check for direct substitutes within the CY7C638xx series, such as the CY7C63803-SXCT, which shares similar electrical characteristics but differs in packaging format. Verify pinout compatibility and software configuration requirements before substituting.
