CY7C65632-48AXCT 개요
A USB 2.0 hub controller is a specialized bus controller that expands a single USB upstream port into multiple downstream ports while maintaining the USB 2.0 protocol envelope. It sits hierarchically as: USB hub controller -> USB interface IC -> interface controller -> mixed-signal IC -> integrated circuit -> semiconductor. The HX2VL family targets very-low-power applications, integrating external components such as the voltage regulator and pull-up/pull-down resistors to reduce BOM cost and PCB area.
Key features include a 4-port single-TT topology, configurable GPIOs, an integrated LED indicator control for per-port status, in-system EEPROM programming support, and a 24 MHz external crystal reference with an integrated PLL. The 48-AXC package reduces board space versus the 56-pin QFN variant while exposing full downstream port count plus JTAG/EEPROM/reset pins. The integrated upstream termination, integrated 1.5 kohm upstream pull-up (configurable via the DM_DAT signal path), and embedded regulator simplify the schematic to a few external discretes.
From an architectural perspective, the HX2VL combines a USB 2.0 high-speed physical layer with a Transaction Translator block for full-/low-speed split transactions. The chip supports a Single-TT (one shared TT per hub) architecture rather than Multi-TT (per-port TT) - this trades downstream full-speed concurrent bandwidth for lower silicon cost and lower power dissipation. Per Infineon datasheet, the embedded regulator provides a 3.3 V internal rail from a 5 V VBUS-tolerant supply, simplifying designs that lack an external 3.3 V LDO.
Typical applications include USB 2.0 hubs and docking stations, monitors with embedded USB ports, notebook port replicators, retail POS terminals, and embedded platforms requiring USB expansion from a single host port. Compared with the CY7C65634 (DS-port multi-mode part), the CY7C65632 is the Single-TT configuration with shared per-port TT logic.
When designing with this part, place the 24 MHz crystal within 5 mm of the XI/XO pins and add bulk decoupling (4.7 uF plus 0.1 uF) close to VCC. Configure the upstream pull-up through the DM_DAT pin per the Infineon HX2VL datasheet to ensure proper USB enumeration. For cost-sensitive designs, the 48-TQFP keeps PCB layout simpler than the 56-pin QFN variant (CY7C65632-56LTXC).

설계 노트
Place the 24 MHz crystal within 5 mm of the XI and XO pins on the CY7C65632-48AXCT with short, symmetric traces to minimize clock skew and EMI. Add a 4.7 uF bulk capacitor plus a 0.1 uF decoupling capacitor adjacent to the VCC pin. Per Infineon HX2VL datasheet layout guidelines, keep the upstream USB D+/D- traces as a 90-ohm differential pair with no splits and route them on the top layer only to maintain USB 2.0 high-speed signal integrity.
Do not connect the upstream D+/D- pull-up resistor externally - the CY7C65632-48AXCT integrates the 1.5 kohm pull-up configurable via the DM_DAT pin per Infineon HX2VL datasheet. Adding an external pull-up causes USB compliance failures. Also, ensure the RESET pin is configured per Infineon community guidance to monitor VBUS through R1/R2 resistors; incorrect reset configuration prevents proper USB enumeration on plug/unplug events.
The CY7C65632-48AXCT integrates a 3.3 V regulator from the 3.15 V to 5.25 V VBUS-tolerant supply; do not add an external 3.3 V LDO unless powering other 3.3 V peripherals. Per Infineon HX2VL datasheet, the integrated regulator handles all internal analog and digital supply rails. Add bulk decoupling (4.7 uF) at VCC and (0.1 uF) adjacent to the supply pin. Power dissipation is approximately 100 mA typical from VBUS during normal hub operation.
Route the downstream port pairs (DM1/DP1 through DM4/DP4) as 90-ohm differential pairs with no splits and matched lengths to within 150 mil. Per Infineon HX2VL datasheet, the per-port over-current sense pins (OC1_N through OC4_N) must connect to the high-side current-sense output of the downstream power switch; place 100 kohm pull-ups to VCC on these pins if no power switch is used. Also, place the EEPROM I2C lines (SDA/SCL) on a separate bus segment from the JTAG lines to avoid crosstalk during programming.
규정 준수 정보
RoHS and REACH compliant per Infineon regulatory documentation. Not AEC-Q100 qualified (commercial temperature grade 0 C to 70 C); for automotive USB hub applications use AEC-Q100 qualified alternatives. HX2VL family is halogen-free per Infineon product documentation.
