CY7C68016A-56LFXC

Application Specific Microcontrollers Overview

The CY7C68016A-56LFXC is a USB peripheral controller from the EZ-USB FX2LP family, manufactured by Infineon Technologies. It integrates an 8051 microcontroller core with 16K x 8 bytes of RAM and features no onboard program memory (ROMless). The device supports High Speed (HS) USB data rates up to 480 Mbps and operates within a supply voltage range of 3V to 3.6V. It is housed in a 56-VFQFN package with exposed pad, measuring 8x8 mm, and is designed for surface-mount installation.

Application Specific Microcontrollers Procurement Notes

This component is classified as Not Recommended for New Designs (NRND) or End-of-Life. Verification of current availability through authorized distributors is required, as stock may be limited to surplus channels. Compliance with RoHS3 standards is confirmed. Moisture Sensitivity Level (MSL) is rated at 3, requiring adherence to specific handling and reflow soldering guidelines.

Application Specific Microcontrollers Selection Notes

Select this part when a ROMless USB controller with high-speed capabilities is needed for custom firmware implementation. Ensure the design accommodates the 56-VFQFN footprint and provides adequate thermal management via the exposed pad. Verify that the host system supports USB High Speed protocols and that the 3V to 3.6V power rail is stable.

Application Specific Microcontrollers Part Context

The CY7C68016A-56LFXC belongs to the EZ-USB FX2LP series, which are widely used for flexible USB connectivity solutions. Unlike variants with embedded EEPROM or Flash, this ROMless version allows full user-defined programming via the USB interface or external bootloaders, offering maximum flexibility for diverse application requirements.

Application Specific Microcontrollers Replacement Considerations

Direct pin-compatible replacements within the same package include other FX2LP variants such as CY7C68013A-56LTXCT, though functional differences like I/O count and internal memory must be evaluated. Cross-referencing with Cypress/Infineon official substitution guides is recommended to ensure electrical and logical compatibility.
