SMSC EVB-USB2514BC Revision A SMSC CONFIDENTIAL - PRELIMINARY USER MANUAL Revision 0.3 (05-19-09) EVB-USB2514BC Evaluation Board Revision A User Guide 1 Overview The SMSC USB2514B MultiTRAKTM is a Low-Power, Full-Featured, OEM configurable, Hi-Speed USB 2.0 compliant hub with four downstream ports. Each of these downstream ports in the USB2514B device is capable of supporting battery charging. The EVB-USB2514BC Evaluation Board demonstrates a standalone application for the hub with all the features listed below and demonstrates advanced power saving options and configurable port assignments. 1.1 1.2 Features 36-pin QFN RoHS compliant package. Four USB 2.0 downstream hub ports with individual port power and over-current sense (OCS). Hi-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) compatible. USB Battery Charging is supported on downstream USB Port 1 to a full 1.5 A. USB Battery Charging is supported on all other downstream USB ports to 500 mA (optional). (In actual use, the port 5 V path, port power controllers, and OCS circuits must be chosen to fully support the specification [ex., USB Port 1]). Multi-Transaction Translator is enabled. Supports internal default hub configuration. Optionally supports configuration from external EEPROM. Low cost 4-Layer space saving design with two outer signal layers, a power inner layer, and a ground inner layer. Individual port over-current sensing. Individual port power control with LEDs for port power indication. Self-powered operation. Operates from a single voltage (5.0 VDC, regulated) external power supply. Single onboard 3.3 VDC regulator. Red LED indicator for "Active" hub state (optional). EMI suppression provided by selection of capacitors and inner power/ground PCB layers. ESD component footprints provided (optional). Single crystal clock source. Schematics, layout, and bill of materials are available to minimize new product development time. General Description The EVB-USB2514BC is an evaluation and demonstration platform featuring the USB2514B Ultra Fast USB 2.0 Hub on a 4-layer RoHS compliant printed circuit board. The EVB-USB2514BC is designed to demonstrate the unique features of this device using a low cost PCB implementation with individual port power control for the downstream USB 2.0 ports. Downstream USB 2.0 port 1 includes a high current port power controller to fully support USB battery charging as a high current walk up port. The EVB-USB2514BC is designed to support internal default configuration settings and an external I2C(R)1 EEPROM (optional) for custom configured functionality. A location is provided for an external I2C EEPROM device for configuration at U6. Figure 2.1 and Figure 2.2 show the top and bottom level silk screen and copper layers. 1.I2C is a registered trademark of Philips Corporation. Revision 0.3 (05-19-09) 2 SMSC EVB-USB2514BC Revision A SMSC CONFIDENTIAL - PRELIMINARY USER MANUAL EVB-USB2514BC Evaluation Board Revision A User Guide 2 Hardware Configuration 2.1 Hardware Description The EVB-USB2514BC has one onboard regulator, which generates 3.3 VDC from an external 5 VDC regulated power supply. The USB2514B generates its own 1.2 VDC for internal use with on-chip 1.2 VDC regulators. The internal 1.2 VDC regulator to the oscillator and the PLL is turned off during suspend to minimize suspend current. The USB2514B consumes power from the 3.3 VDC supply. Downstream port power is distributed by three power switches that consume power from the 5 VDC supply. U2 supplies power to the high current downstream port 1. U1 and U3 supply power to the other three ports at 500 mA. Upstream and downstream port connectors have USB 2.0 compliant decoupling and a separate shield ground. 2.1.1 Port Assignment Downstream ports are numbered 1 through 4 with individual port power controllers. The USB2514B allows any or all of the downstream ports to be configured for high current battery USB charging, and the EVB-USB2514BC is designed to demonstrate that feature. Downstream port 1 is assigned as the default battery charging port with a high current port power controller installed. 2.1.2 USB2514B Configuration Default: The EVB-USB2514B has been set up to support an internal default configuration as determined by the state of the CFG_SEL2, CFG_SEL1, and CFG_SEL0 pins immediately after reset. The vendor ID, product ID, language ID, device ID, and other choices have been set using ROM code defaults. EEPROM Option: The EVB-USB2514B can load configuration from an external two-wire, I 2C EEPROM U6. The EEPROM must be installed at U6, and the configuration option resistors on the CFG_SEL2, CFG_SEL1, and CFG_SEL0 pins changed to enable this option. The EEPROM may be pre-programmed before installation, or be programmed with the USB host using provided SMSC USBDM applications. This option allows access to all of the configuration registers and ID strings for the USB2514B device for detailed functional analysis and exercise as desired. The EVB-USB2514B is compatible with I2C EEPROMs from several manufacturers. The memory capacity must be at least 512 bytes. 2.1.3 Powered State LED An optional LED (LED5) indicates when +5 VDC power is present. 2.1.4 Activity LED An optional LED (LED6) indicates when the USB2514B is active (configured and not suspended). 2.1.5 Port Power LEDs LED1, LED2, LED3, and LED4 indicate when port power is available to the associated downstream USB port. 2.1.6 Connector Description The EVB-USB2514B has a set of standard USB style connectors, one of type B for the upstream port and four of type A for downstream ports. Power is supplied via a 2.0 mm power jack. Table 2.1 lists all of the connectors. For more details on the pinout of these connectors, please see the EVBUSB2514BC schematics on the CD-ROM included with your EVB-USB2514BC.

The PCB layer stackup is shown in Table 2.2. All signals are routed on top and bottom layers. Internal layers are ground and power. Note that the differential signals from the USB2514B match the upstream and downstream port placement simplifying routing of critical signals.
