CY7C68013A-56LTXI

The CY7C68013A-56LTXI from Infineon (formerly Cypress) is a high-speed USB 2.0 peripheral controller with an integrated 8051 microcontroller core, part of the EZ-USB FX2LP family. It provides a complete USB 2.0 transceiver, serial interface engine (SIE), and programmable endpoint FIFOs on a single chip, supporting data rates up to 480 Mbps. The device includes 16 KB of on-chip SRAM for code and data, a General Programmable Interface (GPIF) for glueless connection to a wide range of external parallel interfaces, and a slave FIFO mode that allows external processors or FPGAs to access the USB bus directly. The 56-lead QFN package offers a compact footprint while retaining up to 40 I/O pins, an I²C controller, and an integrated phase-locked loop (PLL) that derives the 48 MHz USB clock from a low-cost 24 MHz crystal.

This controller is widely deployed in industrial instrumentation, test and measurement equipment, medical imaging systems, and data acquisition modules where reliable high-speed USB communication is essential. In practice, the FX2LP often serves as a USB bridge for DSPs, FPGAs, or ASICs that lack native USB connectivity, and its GPIF capability supports direct interfacing to parallel buses without external glue logic. The part number suffix “LTXI” indicates the industrial temperature range (−40°C to +85°C) and the 56-pin QFN package, making it suitable for extended-environment and high-reliability applications. Infineon continues to manufacture and support the FX2LP family under a product longevity program, mitigating obsolescence risk for long-lifecycle industrial and embedded designs.
