USB2517/USB2517I USB 2.0 Hi-Speed 7-Port Hub Controller General Description OEM Selectable Features The 7-Port Hub is a low power, OEM configurable, MTT (multi transaction translator) hub controller IC with 7 downstream ports for embedded USB solutions. The 7port hub is fully compliant with the USB 2.0 Specification and will attach to an upstream port as a Full-Speed Hub or as a Full-/Hi-Speed Hub. The 7-Port Hub supports Low-Speed, Full-Speed, and Hi-Speed (if operating as a Hi-Speed Hub) downstream devices on all of the enabled downstream ports. • Customizable Vendor ID, Product ID, and Device ID • Select whether the hub is part of a compound device (When any downstream port is permanently hardwired to a USB peripheral device, the hub is part of a compound device.) • Flexible port mapping and disable sequence. Ports can be disabled/reordered in any order to support multiple product SKUs. Hub will automatically reorder the remaining ports to match the Host controller's numbering scheme • Programmable USB differential-pair pin location - Eases PCB layout by aligning USB signal lines directly to connectors • Programmable USB signal drive strength. Recover USB signal integrity due to compromised system environments using 4-level driving strength resolution • Select the presence of a permanently hardwired USB peripheral device on a port by port basis • Configure the delay time for filtering the over-current sense inputs • Configure the delay time for turning on downstream port power • Indicate the maximum current that the 347-port hub consumes from the USB upstream port • Indicate the maximum current required for the hub controller • Support Custom String Descriptor up to 31 characters in length for: - Product String - Manufacturer String - Serial Number String • Pin Selectable Options for Default Configuration - Select Downstream Ports as Non-Removable Ports - Select Downstream Ports as Disabled Ports - Select Downstream Port Power Control and Over-Current Detection on a Ganged or Individual Basis - Select USB Signal Drive Strength - Select USB Differential Pair Pin location General Features • Hub Controller IC with 7 downstream ports • High-performance multiple transaction translator MultiTRAK™ Technology provides one transaction translator per port • Enhanced OEM configuration options available through either a single serial I2C EEPROM, or SMBus Slave Port • 64-Pin (9x9 mm) QFN, RoHS compliant package • Supports commercial (0ºC to +70ºC) and industrial (-40ºC to +85ºC) temperature ranges Hardware Features • Low power operation • Full Power Management with individual or ganged power control of each downstream port • On-chip Power On Reset (POR) • Internal 1.8V Voltage Regulator • Fully integrated USB termination and Pull-up/Pulldown resistors • On Board 24MHz Crystal Driver, Resonator, or External 24/MHz clock input • USB host/device speed indicator.

The signals are arranged in functional groups according to their associated interface. The “N” symbol in the signal name indicates that the active, or asserted, state occurs when the signal is at a low voltage level. When “N” is not present before the signal name, the signal is asserted when at the high voltage level. The terms assertion and negation are used exclusively. This is done to avoid confusion when working with a mixture of “active low” and “active high” signals. The term assert, or assertion, indicates that a signal is active, independent of whether that level is represented by a high or low voltage. The term negate, or negation, indicates that a signal is inactive.

Detect Upstream VBUS Power Upstream USB Interfaces VBUS_DET 44 Detects state of Upstream VBUS power. The MCHP Hub monitors VBUS_DET to determine when to assert the internal D+ pull-up resistor (signaling a connect event). When designing a detachable hub, this pin must be connected to the VBUS power pin of the USB port that is upstream from the hub. For self-powered applications with a permanently attached host, this pin must be connected to 3.3V or 5.0V (typically VDD33).
