Product details
Overview
CY7C65642-48AXC from Infineon is a USB 2.0 hub controller with four downstream ports, integrated multiple transaction translators (one per port), 2 KB ROM/64 B RAM MCU, and internal 5 V-to-3.3 V regulator - enabling bus- or self-powered operation in docking stations and monitor hubs.
For engineers reviewing the CY7C65642-48AXC datasheet, CY7C65642-48AXC pinout, CY7C65642-48AXC application, or CY7C65642-48AXC equivalent, this device delivers per-port TT support, configurable VID/PID via EEPROM, ganged/individual power switching, and 12 MHz ±500 ppm crystal–driven PLL timing for high-speed USB host-to-peripheral routing.
Technical Context
The CY7C65642-48AXC implements a dedicated transaction translator per downstream port to handle high-speed split transactions for full/low-speed devices, ensuring compliance with USB 2.0 TID# 30000059. Its hub repeater supports full- and high-speed connectivity between upstream and same-speed downstream ports.
Integrated HS USB control logic manages enumeration, suspend/resume, and frame synchronization with the host, while the on-chip MCU executes configuration decoding and GPIO control - all operating from a single 12 MHz clock source with optional 27/48 MHz oscillator input.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB Compliance | USB 2.0 specification compliant; certified TID# 30000059 - ensures interoperability with standard hosts and peripherals. |
| Downstream Ports | 4 independent ports, each with dedicated transaction translator - enables concurrent full/low-speed device support without bandwidth contention. |
| Power Modes | Bus-powered and self-powered auto-switching - eliminates external power mode selection circuitry. |
| Internal Regulator | Integrated 5 V-to-3.3 V regulator - reduces BOM by removing external LDO; 3.3 V output supplied directly to core logic. |
| Crystal Input | 12 MHz ±500 ppm crystal with 600 µW drive level - enables precise USB timing without external PLL components. |
| Operating Temp | 0°C to +70°C - validated for commercial desktop, monitor, and peripheral enclosure environments. |
| MCU Resources | 2 KB ROM + 64 B RAM - sufficient for boot firmware, EEPROM configuration parsing, and GPIO management without external memory. |

| OVR#1–OVR#4 | Overcurrent fault indicator (active-low) | Open-drain outputs signaling overcurrent condition per port; used for external protection logic. |
| LED1–LED4 | Port status indicator control | Drives external LEDs for connection/activity status; supports dual-color or single-color configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Per-port transaction translator | Enables simultaneous high-speed host communication with multiple full/low-speed peripherals without TT bottlenecking. |
| Configurable port topology | Number of ports, removable/non-removable status, and gang/individual power mode set via EEPROM or I/O pins - no firmware reflash required. |
| Integrated analog components | Eliminates 12 external resistors (termination, pull-up/down) and simplifies power design with internal 5 V-to-3.3 V regulator. |
| ESD recovery with power failure detection | Detects internal supply collapse during ESD events and triggers automatic reset/recovery - improves system robustness in unshielded enclosures. |
| Reference clock flexibility | Accepts 12 MHz crystal or 27/48 MHz oscillator input - allows layout optimization and cost trade-offs between precision and component count. |
Applications
| Docking Station Hub | Monitor Integrated Hub |

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 |
|---|---|---|---|
| USB2514B-AEZG | 4-port hub with single shared TT; no integrated regulator; requires external 3.3 V supply and discrete termination/pull resistors. | Higher BOM count and less suitable for space-constrained bus-powered designs. | Prefer when existing 3.3 V rail is available and cost-per-component is prioritized over integration. |
| CY7C65632-48AXC | Same HX2VL family but with 3 downstream ports; identical pinout and firmware compatibility; lower port count reduces power and thermal load. | Better fit for compact accessories where fourth port is unnecessary. | Select when application requires only three downstream devices and board area/power budget is constrained. |
Compared with USB2514B-AEZG, CY7C65642-48AXC reduces component count and enables simpler power architecture; versus CY7C65632-48AXC, it adds one port with identical integration and thermal profile - making it optimal for full-featured docking and monitor hubs.

FAQ
Does CY7C65642-48AXC support USB Battery Charging (BC) 1.2 specification?
No. The CY7C65642-48AXC does not implement BC 1.2 detection or D+–D− voltage handshake logic. It supports standard USB 2.0 port power switching and overcurrent protection only. Charging functionality must be implemented externally using dedicated BC ICs or host-side negotiation.
Can the upstream port operate at full speed only?
No. The upstream port fully supports high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) modes per USB 2.0 specification. Its HS USB control logic and PHY are qualified to TID# 30000059, ensuring interoperability with high-speed hosts.
Is external EEPROM mandatory for configuration?
No. Configuration can be implemented via mask ROM for fixed setups, eliminating EEPROM. Pin-strapping options allow basic settings (port count, power mode, clock source) without any external memory - ideal for cost-sensitive, high-volume production.
What is the maximum junction temperature during continuous operation?
The CY7C65642-48AXC has a maximum junction temperature of +125°C. Under typical 4-port bus-powered operation with 0°C to +70°C ambient, measured junction temperature remains below +85°C with standard 4-layer PCB layout and 1 oz copper, per thermal resistance data in Rev. *O datasheet Section 12.
