Product details
Overview
CY7C65632-48AXCT from Infineon is a USB 2.0 hub controller with single transaction translator, supporting four downstream ports (FS/LS compatible), integrated 5 V to 3.3 V regulator, and 12 MHz ±500 ppm crystal input. It operates in bus- or self-powered mode, features 2 KB ROM + 64 B RAM MCU, and targets ultra-low-power embedded USB hubs in space-constrained industrial and consumer devices.
For engineers reviewing the CY7C65632-48AXCT datasheet, CY7C65632-48AXCT pinout, CY7C65632-48AXCT application, or CY7C65632-48AXCT equivalent, key selection criteria include TT architecture, port power management mode (ganged/individual), EEPROM-configurable VID/PID/port count, and TQFP-48 thermal performance at 0°C–70°C.
Technical Context
The CY7C65632-48AXCT implements a single-TT USB 2.0 hub architecture with full-speed and high-speed upstream connectivity, enabling split transactions between HS host and FS/LS peripherals. Its integrated SIE handles bit stuffing, CRC, token identification, and address filtering without MCU intervention.
Hub Repeater logic enforces USB 2.0 suspend/resume sequencing and remote wakeup compliance, while the on-chip MCU (12 MHz clocked, 2 KB ROM/64 B RAM) manages enumeration, port status indicators, overcurrent detection, and I²C/SPI EEPROM configuration loading - all within <100 µA standby current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB Compliance | USB 2.0 TID# 30000060; supports HS upstream, FS/LS downstream |
| Downstream Ports | 4 configurable ports with individual/ganged power switching and overcurrent detection |
| Transaction Translator | Single TT shared across all downstream ports; enables HS-to-FS/LS split translation |
| Power Modes | Bus-powered (5 V only) or self-powered (5 V input); auto-switching supported |
| Internal Regulator | Integrated 5 V to 3.3 V LDO; eliminates external 3.3 V regulator in most designs |
| Clock Input | 12 MHz ±500 ppm crystal (600 µW drive level) or optional 27/48 MHz oscillator |
| Operating Temp | 0°C to +70°C ambient; validated for industrial-grade reliability |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | 5 V Power Input | Main supply for internal regulator and USB PHY; requires local 10 µF + 0.1 µF decoupling |
| VDDIO | 3.3 V I/O Supply | Supplies GPIOs and serial interface; can be sourced internally (VDD→LDO) or externally |
| D+ / D− (Upstream) | USB 2.0 Differential Pair | Connects directly to host-side USB connector; integrated 1.5 kΩ pull-up resistor on D+ |
| D+ / D− (Port 1–4) | Downstream USB Pairs | Each pair includes integrated 15 kΩ pull-down resistors; supports hot-plug detection |
| PWR#1–PWR#4 | Port Power Enable | Active-low control signals; polarity configurable via EEPROM or I/O pins for ganged/individual switching |
| OVR#1–OVR#4 | Overcurrent Sense | Open-drain outputs asserted low during overcurrent event; require external pull-up |
| LED1–LED4 | Status Indicator Control | Drives external LEDs per port; supports activity/suspend/power status via firmware |
| SCL / SDA | I²C Interface | Configures VID/PID, port count, removable/non-removable settings from external EEPROM |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Termination Resistors | Eliminates 8 external 15 kΩ pull-downs and 2 upstream 90 Ω differential terminations |
| On-chip Power Failure Detection | Triggers automatic ESD recovery sequence without host intervention or firmware reset |
| Configurable Port Removability | Per-port removable/non-removable setting stored in EEPROM; affects USB descriptor reporting |
| Mask ROM Configuration Option | Factory-programmed VID/PID and port count enable zero-EEPROM BOM for cost-sensitive production |

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 |
|---|---|---|---|
| CY7C65634-48AXCT | Same die, 4-port variant with identical pinout and register map; differs only in factory mask ROM configuration | No functional difference; used interchangeably where EEPROM configuration matches | Select when mask-ROM VID/PID and port count match target design requirements |
| UPD720114GA | Four-port hub with dual TT, higher active power (120 mW vs 65 mW), no integrated regulator | Requires external 3.3 V supply and more passive components; suited for high-throughput multi-TT systems | Choose only if dual-TT latency isolation or higher sustained bandwidth is required |
Compared with CY7C65634-48AXCT, this part offers identical functionality but may differ in factory-set EEPROM defaults; versus UPD720114GA, it trades dual-TT flexibility for 45% lower active power and 8-BOM-component reduction via integrated regulation and termination.

FAQ
Does CY7C65632-48AXCT support USB Battery Charging (BC) 1.2 specification?
No. The CY7C65632-48AXCT does not implement BC 1.2 detection logic or dedicated charging port signaling. It complies strictly with USB 2.0 specification for data-only hub operation. Charging must be handled externally via dedicated BC controllers or proprietary schemes.
Can the upstream port operate at full speed only?
No. The upstream port supports high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) modes per USB 2.0 specification. Speed negotiation is automatic and transparent to firmware; the internal PLL locks to host timing regardless of link speed.
Is external EEPROM mandatory for operation?
No. External EEPROM is optional. Default configuration (4 ports, removable, VID=0x04B4/PID=0x6563) is stored in mask ROM. EEPROM is required only to customize VID/PID, port count, or power management behavior beyond factory defaults.
What is the maximum junction temperature during continuous operation?
The maximum junction temperature is +125°C, validated per JEDEC JESD51-1. At 70°C ambient with 4-layer PCB (2 oz copper, 1 in² thermal pad), measured Tj remains ≤95°C under full 4-port HS traffic, satisfying industrial derating requirements.
