TetraHub™ Controller
Cypress Semiconductor Corporation • 198 Champion Court • San Jose, CA 95134-1709 • 408-943-2600
Document Number: 001-65659 Rev. *I Revised April 10, 2017
HX2VL – Very Low Power USB 2.0 TetraHub™ Controller
Features
■ High-performance, low-power USB 2.0 hub, optimized for
low-cost designs with minimum bill-of-material (BOM).
■ USB 2.0 hub controller
❐ Compliant with USB2.0 specification, TID# 30000059
❐ Up to four downstream ports support
❐ Downstream ports are backward compatible with FS, LS
❐ Multiple translator (TT), one per downstream port for
maximum performance.
■ Very low-power consumption
❐ Supports bus-powered and self-powered modes
❐ Auto switching between bus-powered and self-powered
❐ Single MCU with 2 K ROM and 64 byte RAM
❐ Lowest power consumption.
■ Highly integrated solution for reduced BOM cost
❐ Internal regulator – single power supply 5 V required.
❐ Provision of connecting 3.3 V with external regulator.
❐ Integrated upstream pull-up resistor
❐ Integrated pull-down resistors for all downstream ports
❐ Integrated upstream/downstream termination resistors
❐ Integrated port status indicator control
❐ 12-MHz +/-500 ppm external crystal with drive level 600 W
(integrated PLL) clock input with optional 27/48-MHz
oscillator clock input.
❐ Internal power failure detection for ESD recovery
■ Downstream port management
❐ Support individual and ganged mode power management
❐ Overcurrent detection
❐ Two status indicators per downstream port
■ Maximum configurability
❐ VID and PID are configurable through external EEPROM
❐ Number of ports, removable/non-removable ports are
configurable through EEPROM and I/O pin configuration
❐ I/O pins can configure gang/individual mode power
switching, reference clock source and polarity of power
switch enable pin
❐ Configuration options also available through mask ROM
■ Available in space saving 48-pin TQFP (7 × 7 mm) and 28-pin
QFN (5 × 5 mm) packages
■ Supports 0 C to +70 C temperature range

■ Overview: USB Portfolio, USB Roadmap
■ USB 2.0 Hub Controller Selectors: HX2LP, HX2VL
■ Application notes: Cypress offers a large number of USB appli-
cation notes covering a broad range of topics, from basic to
advanced level. Recommended application notes for getting
started with HX2VL are:
❐ AN72332 - Guidelines on System Design using Cypress's
USB 2.0 Hub (HX2VL)
❐ AN69235 - Migrating from HX2/HX2LP to HX2VL
■ Reference Designs:
❐ CY4608 HX2VL Very Low-Power USB 2.0 Compliant 4-Port

■ Models: HX2VL (CY7C65632/34/42) - IBIS
HX2VL Development Kit
HX2VL Development Kit board is a tool to demonstrate the features of HX2VL devices (CY7C65632, CY7C65634). In the initial phase
of the design, this board helps developers to understand the chip features and limitations before proceeding with a complete design.
The Development kit includes support documents related to board hardware, PC application software, and EEPROM configuration
data (.iic) files.
