8051 USB engine with external firmware storage
The Infineon CY7C68013A-56PVXCT is an EZ-USB FX2LP™ USB microcontroller built around an 8051 core, designed as a high-speed USB peripheral controller for applications like data acquisition, imaging, and test equipment that need a USB 2.0 interface with local processing. It integrates 16K x 8 of internal RAM for code and data, but the program memory type is ROMless — meaning the firmware must reside in an external serial or parallel memory device (such as an I²C EEPROM or parallel Flash) that the 8051 boots from over the I²C or USB interface. The 24 general-purpose I/O pins, combined with I²C, USB, and USART interfaces, give it the connectivity to handle control, data streaming, and host communication in a single chip.
This part is not rated for industrial, automotive, or outdoor environments where extended temperature or humidity cycling is expected. For designs that need the same USB peripheral function across a wider temperature span, the EZ-USB FX2LP family includes industrial-temperature variants; verify the suffix before committing the BOM if the end equipment sees more than 70°C ambient.
Package and assembly — 56-SSOP footprint
Housed in a 56-BSSOP package (0.295" body width, 7.50mm width, 0.635mm pitch), the CY7C68013A-56PVXCT is a surface-mount SSOP that reflows with standard lead-free profiles. The supplier device package is 56-SSOP, and the tape-and-reel or cut-tape options suit both prototyping and volume pick-and-place.
For volume commitments or long-term supply agreements, the active lifecycle means no forced redesign horizon from this component.
