Product details
Overview
CY7C65630-56LTXC from Cypress Semiconductor is a 4-port, single-transaction-translator (1-TT) USB 2.0 hub controller supporting high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) operation with integrated USB 2.0 PHYs, internal voltage regulator, and on-chip termination/pull-up/pull-down resistors. It operates from a single 3.3 V supply and uses a 24 MHz external crystal with integrated PLL for clock generation. Designed for space-constrained industrial and automotive applications (–40 °C to +85 °C), it enables compact, low-BOM USB hub solutions in docking stations and monitor hubs.
For engineers reviewing the CY7C65630-56LTXC datasheet, CY7C65630-56LTXC pinout, CY7C65630-56LTXC application, or CY7C65630-56LTXC equivalent, key selection criteria include downstream port count (4), TT architecture (single), power mode support (bus/self-powered), EEPROM configurability (VID/PID/port enable/power settings), and QFN-56 package compatibility with CY7C65640.
Technical Context
The CY7C65630 implements a USB 2.0 hub repeater for same-speed traffic (e.g., high-speed upstream to high-speed downstream) and a dedicated transaction translator (TT) for speed translation between high-speed upstream and full-/low-speed downstream devices. Its routing logic dynamically assigns ports to either path based on attached device speed.
Configuration is loaded at power-up from an external SPI EEPROM, enabling runtime customization of VID/PID/DID, active/removable port count, overcurrent detection polarity/timing, port indicator behavior, and ganged vs. individual power switching - all without firmware changes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB 2.0 hub controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C65640-56LTXC | Pin-for-pin compatible, identical 4-port/1-TT architecture and feature set | No functional difference; CY7C65640 is legacy part with same footprint and electrical specs | Select CY7C65630 for new designs - CY7C65640 is obsolete per Cypress PCN-190115 |
| UPD720114GA | 4-port, 2-TT architecture; supports concurrent full-speed transfers; requires 1.05 V core + 3.3 V I/O supplies | Better throughput for mixed full-speed devices but higher BOM complexity and power consumption | Choose UPD720114GA only when concurrent full-speed bandwidth >12 Mbps is required |
Compared with CY7C65640-56LTXC, CY7C65630-56LTXC offers identical functionality with updated lifecycle status; versus UPD720114GA, it trades concurrent full-speed capability for lower power, simpler power delivery, and reduced passive count - ideal for cost- and space-constrained industrial hubs.

FAQ
Does CY7C65630-56LTXC require an external crystal?
Yes - it requires a 24 MHz fundamental-mode quartz crystal connected to XTAL_IN/XTAL_OUT. The internal PLL generates the 480 MHz clock needed for USB 2.0 high-speed operation. No external oscillator is needed, but the crystal must meet specified load capacitance (12 pF) and stability (±50 ppm) requirements per datasheet Section 23.
Can CY7C65630-56LTXC operate in bus-powered mode without external power regulation?
Yes - its internal regulator accepts 4.4 V to 5.25 V VBUS input and delivers regulated 3.3 V to the core and I/O. All USB transceivers, logic, and port drivers operate from this single rail, eliminating need for external DC/DC or LDO in bus-powered designs compliant with USB 2.0 power budgets.
How is port power switching implemented on CY7C65630-56LTXC?
Each downstream port has a dedicated PWR# output that drives the gate of an external N-channel MOSFET. Configuration via SPI EEPROM determines whether ports are ganged (all PWR# tied together) or individually controlled. The IC asserts PWR# high to enable power; OVR# signals fault conditions independently per port.
Is CY7C65630-56LTXC compatible with USB 3.x hosts or peripherals?
No - it is strictly a USB 2.0 hub controller. It connects only to USB 2.0 upstream hosts and downstream peripherals. When connected to a USB 3.x port, it operates in USB 2.0 backward-compatible mode (using the SS lane's USB 2.0 sideband). It does not support SuperSpeed (5 Gbps) signaling or associated protocols.
