• Includes built-in battery charger detection capabilities compliant with USB specifications.
• Features internal flash memory for storing customizable USB descriptors and system parameters.
• Provides flexible general-purpose input/output pins with configurable drive states.

Controllers Applications

• Medical and healthcare devices
• Point-of-Sale terminals
• Test and measurement systems
• Gaming systems
• Industrial networking equipment

Controllers Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to ensure correct packaging and temperature grade. Confirm that the required driver software matches the target operating system version. Check for any regional distribution restrictions or supply limitations before finalizing procurement plans.

Controllers Selection Notes

Select this component when a dedicated USB-to-SPI bridge is required without firmware development. Ensure the application utilizes the vendor class protocol rather than CDC if standard virtual COM drivers are not desired. Verify that the SPI clock frequency requirements align with the master or slave operational limits defined in the datasheet.

Controllers Part Context

This part belongs to the EZ-USB Serial Bridge Controller family, designed for legacy peripheral connectivity. It serves as a drop-in replacement for complex custom USB interfaces by offloading protocol handling. The device simplifies design by integrating necessary oscillators and regulators on-chip.

Controllers Replacement Considerations

CY7C652148-24LTXIT is the tape-and-reel variant of the same functional device. Cross-reference with other USB-SPI controllers in the family only if pinout compatibility and specific protocol support requirements differ significantly.

Controllers FAQ

What is the default SPI configuration mode?

The default configuration is SPI Master mode. It can be reconfigured to SPI Slave mode using the provided configuration utility.

Does the device support hardware flow control?

No, the CY7C652148 does not support hardware flow control. It relies on software-based flow management for SPI transactions.

How is the remote wakeup feature enabled?

Remote wakeup is enabled via the configuration utility. It requires the host to enable the feature through the SET_FEATURE request during enumeration.
