Product details
Overview
CY7C65630-56LTXIT from Cypress Semiconductor is a 4-port USB 2.0 hub controller with single transaction translator (1TT), integrated USB 2.0 PHYs, internal 24 MHz PLL, and on-chip termination/pull-up/pull-down resistors. It operates from a single 3.3 V supply, supports bus- and self-powered modes, and targets low-power embedded USB expansion in industrial and automotive temperature ranges (–40 °C to +85 °C).
For engineers reviewing the CY7C65630-56LTXIT datasheet, CY7C65630-56LTXIT pinout, CY7C65630-56LTXIT application, or CY7C65630-56LTXIT equivalent, key selection criteria include downstream port count (4), TT architecture (single), EEPROM-configurable VID/PID/port 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 serial interface engine (SIE) handles bit stuffing, checksum generation, and address checking autonomously.
Configuration is loaded at power-up from an external SPI EEPROM, enabling runtime customization of port count, removable status, overcurrent detection mode, LED polarity, and string descriptors. The device integrates 1.5 kΩ upstream pull-up, 15 kΩ downstream pull-down, and series termination resistors on all D+/D− lines - eliminating 12 external passives.

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 |
|---|---|---|---|
| CY7C65640-56LTXI | Same 4-port/1TT architecture; identical pinout and electrical specs; differs only in qualification grade (industrial vs. commercial temp range) | CY7C65640 rated for 0 °C to +70 °C; lacks automotive/industrial temp validation | Select CY7C65640 only if ambient operating temperature remains within commercial range and cost is primary constraint |
| UPD720114GA | 4-port/2TT architecture; higher concurrent full-speed bandwidth; requires external 1.2 V supply and more passives | Supports dual-TT for improved mixed-speed throughput; not pin-compatible; larger footprint | Choose UPD720114GA when application demands higher full-/low-speed device concurrency and board area is not constrained |
Compared with CY7C65640-56LTXI, the CY7C65630-56LTXIT offers extended temperature operation and identical functionality; versus UPD720114GA, it trades dual-TT bandwidth for lower BOM count, smaller QFN-56 footprint, and single-supply simplicity.

FAQ
What is the minimum required external component count for basic CY7C65630-56LTXIT operation?
A functional CY7C65630-56LTXIT design requires only a 24 MHz crystal, decoupling capacitors, and an SPI EEPROM (if configuration persistence is needed). All USB termination, pull-up, and pull-down resistors are integrated - eliminating 12 discrete passives typically required in competing hub ICs.
Does CY7C65630-56LTXIT support both bus-powered and self-powered hub configurations?
Yes. The device supports both modes via EEPROM configuration. In bus-powered mode, it draws power from upstream VBUS and uses internal regulators to supply core logic. In self-powered mode, it accepts an external 3.3 V supply and disables VBUS sensing, enabling operation even when upstream port is unpowered.
How is overcurrent protection implemented on downstream ports?
Each downstream port has a dedicated OVR# input that monitors external current-sense circuitry. The device supports two modes: latched (port remains disabled until host issues ClearPortFeature) or auto-retry (port re-enables after timeout). Mode selection and timeout duration are configured via SPI EEPROM during initialization.
Can CY7C65630-56LTXIT be used in USB-C applications?
No. CY7C65630-56LTXIT is a standard USB 2.0 Type-A hub controller with fixed upstream/downstream D+/D− pins. It does not support USB-C alternate modes, CC logic, or reversible connector detection. For USB-C hub applications, a companion USB-C PD controller (e.g., CYPD3177) must be added externally.
