Product details

What this 8051 USB microcontroller brings to the board

The Infineon CY7C68014A-100AXC is a USB microcontroller built around an 8051 core, designed to handle high-speed USB peripheral duties without needing a separate protocol engine.

ROMless means external flash is mandatory

This part is ROMless — there is no on-chip program memory. The 8051 boots from an external I²C EEPROM or is loaded over USB by the host during enumeration.

This keeps it in indoor gear — desktop peripherals, test equipment, USB hubs, data acquisition front-ends, consumer electronics. Not for under-hood automotive, outdoor telecom cabinets, or unheated factory floors. The 100-LQFP package is surface-mount only; plan for a standard reflow profile.

Active lifecycle and compliance

The ROHS3 stamp covers the current regulatory requirements for most markets.
