CY7C65634-48AXC

Controllers Overview

The CY7C65634-48AXC is a USB high-speed hub controller from Infineon Technologies, part of the HX2VL series. It supports USB 2.0 standards with data rates of 12 Mb/s and 480 Mb/s. The device operates within a supply voltage range of 3.15 V to 5.25 V and draws a working power current of 77.46 mA. Designed for surface mount installation, it is housed in a 48-TQFP (7x7) package. The component functions reliably across an operating temperature range of 0°C to 70°C.

Controllers Feature Summary

• Supports USB 2.0 High Speed (480 Mb/s) and Full Speed (12 Mb/s) data transmission protocols.
• Integrated hub controller functionality for expanding USB connectivity.
• Operates on a wide voltage input range suitable for various system power architectures.

Controllers Applications

• Adapters and chargers
• Home entertainment systems
• Mobile devices

Controllers Procurement Notes

Verify the specific suffix '48AXCT' against the requested model when sourcing, as packaging formats such as tape-and-reel or cut-tape may differ while maintaining identical electrical specifications. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements prior to assembly planning to ensure supply chain alignment with manufacturing constraints.

Controllers Selection Notes

Select this component for designs requiring a dedicated USB 2.0 hub controller with low power consumption characteristics. Ensure the PCB layout accommodates the 48-LQFP package dimensions. Verify that the host system provides stable voltage within the 3.15 V to 5.25 V range to maintain optimal signal integrity and operational stability during high-speed data transfers.

Controllers Part Context

This component belongs to the EZ-USB HX2VL family, which focuses on very low-power USB 2.0 hub solutions. It serves as a successor or alternative to previous generations like the CY7C65631, offering improved power efficiency while maintaining compatibility with standard USB host controllers and peripheral devices in compact form factors.

Controllers Replacement Considerations

The CY7C65631-56LTXC is documented as a potential replacement option, though it utilizes a QFN-56 package instead of TQFP-48. Verify pinout compatibility and thermal management requirements before substituting, as the package change necessitates PCB redesign considerations.
