概述

Description

CY7C63743-SXC is a Cypress USB 2.0 hub controller IC. It implements a USB hub with one upstream port to the host and multiple downstream ports (the CY7C6374x family typically supports up to four). It includes the USB 2.0 transceivers, hub arbitration logic, port power switches with overcurrent protection, and basic hub management features to enable embedded USB hubs with high-speed (480 Mbps) and full-speed operation.
Use cases: adding multiple USB ports to an embedded system, docking stations, peripherals, or automotive/industrial apps where a compact hub is needed.
Operation: usually controlled by a host MCU or embedded processor to configure descriptors, handle control requests, and manage port power; some variants can operate with limited firmware for standalone tasks. See the datasheet for exact pinout, electrical specs, package (SXC) details, and memory/ROM options.

Features

Here are the core features of CY7C63743-SXC (EZ-USB family):
- USB 2.0 Hi-Speed peripheral controller with integrated PHY (480 Mbps) and full-speed compatibility
- On-chip 8051-based microcontroller for firmware and device logic
- On-chip RAM and ROM for firmware/data; supports external memory interface
- DMA engine with endpoint FIFOs for high-throughput USB data transfer
- Flexible endpoint architecture: multiple endpoints (including bulk, interrupt, and isochronous)
- Programmable USB descriptors and device classes via firmware (e.g., HID, MSC, CDC)
- General-purpose I/O pins with configurable directions and drive strength
- Clocking options with USB-required 48 MHz operation (PLL) from a crystal
- Power options: bus-powered or self-powered, with power management and suspend/resume support
- Development ecosystem: Cypress EZ-USB tools, sample firmware, and evaluation/support resources
Note: exact memory size, number of endpoints, and package details vary by variant; verify datasheet for the SXC-specific specs.

Package

CY7C63743-SXC is packaged in a 64‑pin LQFP (Thin Quad Flat Pack). For exact dimensions and pinout, consult the Cypress/Fab datasheet.

Pinout

- Pin count: 28-pin package (SXC variant, SSOP-28 style).
