CY7C68300C-56LFXC

CY7C68300C-56LFXC is a Cypress EZ-USB USB 2.0 controller device in a 56‑pin lead-free LQFP package. It is used to implement USB peripherals (and, in some contexts, bridge devices) by handling the USB signaling and protocol while a host MCU or processor runs application logic. The device includes a USB transceiver and a programmable USB protocol engine, with configurable endpoints and on‑chip memory for firmware data, enabling data movement between the USB bus and the host system. It is commonly employed in custom USB peripherals (HID, mass storage, serial bridges, data loggers, USB-to-serial adapters, etc.). Programming is done via firmware loaded into on‑chip RAM/flash, depending on the variant. Package type: 56‑pin LQFP with RoHS lead-free finish. For exact details (pinout, electrical specs, memory map, endpoint configuration, programming method), refer to the CY7C68300C datasheet and Cypress application notes.

CY7C68300C-56LFXC is part of Cypress/Infineon’s EZ-USB FX2LP family. Near direct replacements: CY7C68013A-56LFXC and CY7C68013A-56LTXC. Functional equivalents (USB 2.0 MCU / USB-FIFO bridge) include FTDI FT2232H, Microchip PIC32/PIC24 USB MCUs, and NXP LPC17xx/LPC43xx. Verify pinout, power and firmware compatibility before substituting.
