USB2503A-HZH

USB2503A-HZH - USB 2.0 3-Port Hub Controller | Microchip

Microchip USB2503A-HZH is a USB 2.0-compatible three-port USB hub controller with a 48-QFN-EP 7 x 7 mm package. It supports low-speed operation at 1.5 Mb/s, full-speed operation at 12 Mb/s, and high-speed operation at 480 Mb/s. The controller operates from 1.62 V to 3.6 V and includes three transaction translators, flexible configuration options, and selectable downstream-port power management. A USB hub controller is an interface IC within the USB interface-controller hierarchy. It connects one upstream USB host connection to multiple downstream USB ports, allowing peripherals such as storage devices, keyboards, network adapters, and industrial USB modules to share one host port. Unlike a host controller that manages operating systems and device software, the USB2503A-HZH handles USB signaling, port transactions, configuration, and power distribution while requiring no firmware development. The principal features include full USB 2.0 operation, one transaction translator per downstream port, low-speed, full-speed, and high-speed device support, per-port or ganged power control, and detection of both bus-powered and self-powered operating conditions. Configuration can use pin-selectable defaults, an external serial EEPROM, or a microcontroller interface. When the microcontroller interface is used, the hub operates as an SMBus slave device. In the architecture described by the Microchip USB2503/USB2503A datasheet 00002249A, dynamic power switching monitors the external SELF_PWR input. If the available power source changes, the hub disconnects downstream devices and the upstream connection before reattaching in the appropriate bus-powered or self-powered configuration. External 10 kΩ pull-up resistors are recommended on SDA/SMBDATA and SCL/SMBCLK/CFG_SEL0 lines according to the SMBus 1.0 Specification and EEPROM-manufacturer guidance. Typical implementations include compact desktop USB expansion, USB-to-serial systems, embedded equipment with multiple service connections, data-acquisition equipment, and powered peripherals. The three downstream ports are useful when a compact host interface must support several external devices without adding another system controller. The primary design constraint is accurate implementation of USB power, signal routing, configuration straps, and exposed-pad thermal management. Maintain the specified USB differential routing and supply decoupling, and verify the external power-source transition behavior before enabling downstream loads. Because the available web data does not provide a complete pin table, designers should use the manufacturer datasheet for final pin assignments and layout values. This page consolidates the verified USB 2.0 speeds, operating range, package information, configuration methods, and sourcing links for USB2503A-HZH. It also identifies the manufacturer's recommended USB2513B replacement direction while clearly distinguishing a documented replacement path from a verified pin-for-pin drop-in substitute.

The Microchip Technology USB2504-JT is a USB 2.0 four-port hub controller with no firmware development required, supporting low-speed 1.5 Mb/s, full-speed 12 Mb/s, and high-speed 480 Mb/s downstream operation in a 64-pin TQFP package measuring 10 x 10 mm. The controller integrates the hub interface logic needed to manage four USB downstream ports while attaching to a USB host. An integrated USB hub controller is a semiconductor interface device that expands one host USB connection into multiple downstream ports. It sits between a USB host and peripherals, handling port attach, disconnect, enumeration, power-gating, and traffic routing. The USB2504 family is positioned within the USB interface-controller and peripheral-controller hierarchy, providing infrastructure for USB hubs without requiring a separate hub firmware. Key features include compliance with the USB 2.0 specification, four downstream ports, firmware-free configuration, low-speed, full-speed, and high-speed downstream support, and operation from a 3 V to 3.6 V supply according to the USB2504A-JT comparison data. Configuration can use strapping options, an external EEPROM, or a microcontroller interface; when connected to a microcontroller, the hub appears as an SMBus slave device. The controller is designed for USB hubs, docking stations, KVM equipment, and embedded systems that need more than one USB port. Its 64-pin TQFP package provides the required external connectivity for four downstream channels and upstream USB signaling. USB 2.0 hub designs must still provide correct power distribution, downstream-port protection, layout routing, and connector implementation; the controller itself does not eliminate those board-level requirements. A key design consideration is power budgeting. Each enabled downstream port can require current for attached USB devices, so the power supply, switches, protection components, and connector wiring must be sized for the worst-case load. High-speed USB traces also require controlled impedance, short return paths, and careful separation from noisy power and switching circuitry. Microchip documentation provides configuration guidance for EEPROM and microcontroller-based implementations. This page synthesizes verified manufacturer and distributor information, cross-reference results, package details, and practical engineering considerations. It distinguishes documented USB2504 features from parameters that require confirmation in the manufacturer datasheet, helping engineers evaluate the USB2504-JT for four-port USB hub designs.

According to the Microchip product page, the device is fully USB 2.0 compliant and requires no firmware development. Configuration can begin with pin-selectable defaults, limited strapping options, an external EEPROM, or a microcontroller interface. When configured through a microcontroller, the hub appears as an SMBus slave, allowing an external controller to alter supported configuration options. Dynamic power switching monitors the SELF_PWR input and removes downstream and upstream power when local supply availability changes. Typical uses include USB 2.0 docking stations, desktop hubs, KVM equipment, external storage interfaces, embedded USB expanders, and industrial peripheral hubs. Four high-speed transaction translators make the controller appropriate when several peripherals must coexist behind one host connection without relying on USB firmware. PCB design must preserve high-speed USB routing discipline, including a short upstream path, controlled impedance, continuous reference planes, and placement of required decoupling close to the device. The exact pin names, capacitor values, clock requirements, operating temperature, and power ratings must be confirmed against the manufacturer datasheet before layout release. This page consolidates the verified manufacturer and distributor facts, distinguishes the explicitly supported USB2504-JT cross-reference from unsupported substitutions, and identifies engineering details that still require direct datasheet confirmation.

USB2507-ADD

USB2507-ADD - USB 2.0 7-Port Hub | Microchip Technology

The Rochester Electronics USB2507-ADD is an integrated USB 2.0-compatible seven-port hub controller based on the SMSC USB2507, packaged in an 80-pin TQFP measuring 12 x 12 mm. It supports seven downstream USB connections at low speed, 1.5 Mb/s, full speed, 12 Mb/s, and—when attached to a high-speed host—high speed, 480 Mb/s. Configuration does not require custom firmware, making the device suitable for embedded USB expansion, legacy PC systems, printers, storage peripherals, and industrial equipment. A USB hub controller is an interface IC that bridges one upstream USB host connection to multiple downstream ports while transaction translators isolate traffic on each active link. Within the USB interface hierarchy, the USB2507 family belongs to the seven-port hub-controller class and implements USB 2.0 connectivity. Per-port or ganged downstream power control can be selected, while bus-powered and self-powered source conditions can be detected. Configuration can use strapping options, an external EEPROM, or a microcontroller interface; with the latter, the hub operates as an SMBus slave. Key verified capabilities include seven transaction translators, operation at 1.5 Mb/s, 12 Mb/s, and 480 Mb/s, full power management, selectable per-port or ganged power control, and bus-power or self-power detection. The controller also supports an on-board 24 MHz crystal driver or a 24 MHz external clock, an internal PLL for 480 MHz USB 2.0 sampling, and an integrated 1.8 V linear voltage regulator. These blocks reduce the external clock, timing, and supporting circuitry normally required by a multiport USB hub. The -ADD order code is offered in the same 80-TQFP, 12 x 12 mm package identified for USB2507-ADT by the verified distributor data. Because both parts use the same base USB2507 family, that package relationship supports direct footprint reuse, although functional equivalence should still be confirmed against the manufacturer pin table and ordering information. The manufacturer documentation also identifies SMBus and serial configuration paths, supporting designs that require adjustable runtime or manufacturing configuration. Typical installations include legacy industrial computers, medical carts, test systems, peripheral concentrators, USB-to-serial equipment, and embedded platforms needing more than the host controller's native ports. In a typical design, one upstream USB line connects to the host, while seven downstream routes connect to internal or external connectors. The principal engineering constraints are USB differential routing, correct power budgeting, connector protection, support for bus- or self-powered operation, and compliance with the electrical requirements stated in the manufacturer datasheet. When laying out the board, treat the differential USB pairs as controlled-impedance nets and keep upstream and downstream routing separated to minimize crosstalk. Provide the crystal or supported 24 MHz clock network exactly as specified, place decoupling close to the supply pins, and confirm that downstream power switches can meet the required inrush and over-current behavior. The USB2507-ADD can simplify firmware development, but it does not remove the need for correct host support, power architecture, connector design, and USB signal integrity.

Verified product information identifies seven downstream ports, USB 2.0 compatibility, and support for low-speed, full-speed, and high-speed devices. Search results also describe an internal 24 MHz crystal-driver circuit or external 24 MHz clock source, an internal phase-locked loop for 480 Mbit/s sampling, an internal 1.8 V linear regulator, integrated USB terminations and bias resistors, and short-circuit protection on USB differential pins. These functions support a compact hub implementation while reducing external clock and signal-conditioning overhead. Configuration flexibility is provided through strapping options, an external EEPROM, or a microcontroller interface. Search data indicates that a microcontroller-connected hub appears as an SMBus slave, while strap options modify a limited subset of configuration choices. This allows prototype settings to change without firmware and production designs to use persistent configuration when required. Typical uses include USB docking stations, external storage connectivity, laboratory equipment, computer-accessory consolidation, and embedded systems that need seven downstream USB connections. The controller should be paired with suitable hub-board power switching, protection, connectors, and layout that preserves USB differential-signal integrity. Designers must also verify the current electrical limits, pin functions, clock source, and reference configuration directly against the manufacturer datasheet before layout release. The principal design consideration is that USB hub design combines high-speed edge-rate signaling with exposed connector paths. Controlled impedance, short matched traces, careful return paths, correct terminations, and verified power-supply sequencing are essential. The 80-pin TQFP footprint is not interchangeable with a smaller controller without a PCB redesign, even when another hub offers the same USB version. This product record combines the verified Microchip USB2507 data, official datasheet links, distributor package information, configuration details, and practical implementation guidance. It is intended to support engineering selection and sourcing, while flagging missing electrical, lifecycle, pricing-tier, pinout, and compliance values rather than inventing them.

System designers must still verify USB enumeration, power-budget, and downstream-device compatibility requirements. The principal design consideration is power management. Port power-switch control and overcurrent protection should be coordinated with the required downstream current budget, while internal-regulator and decoupling requirements must follow the manufacturer reference design. Signal-routing practice should preserve USB differential-pair geometry and provide the required protection and connection details. This page consolidates the verified USB2512BT/M2 specifications, distributor availability records, package information, and same-family replacement data. It also separates confirmed parameters from unavailable technical details and identifies the engineering trade-offs that matter when comparing a two-port USB 2.0 hub controller with other hub implementations.

It provides an integrated solution for expanding a single USB host connection into two USB ports in embedded equipment. The controller also supports I2C management, port mapping, and single-transaction-translator hub operation. A USB hub controller is an interface integrated circuit that coordinates traffic between one upstream host port and multiple downstream peripherals. The USB2512I-AEZG belongs to the USB 2.0 interface-controller hierarchy, where transaction translators separate low-speed, full-speed, and high-speed traffic and permit mixed-speed devices to share a host port. This makes the device useful where a compact peripheral needs more connectivity than a single USB port can provide. Key features include one upstream USB 2.0 connection, two downstream USB 2.0 ports, a 3 V to 3.6 V operating supply range, and a typical current draw of 95 mA. The industrial-temperature-rated version is identified by the I suffix, while the 36-pin QFN package uses a 0.50 mm pitch and includes an exposed thermal pad for improved heat dissipation. The device uses Microchip MultiTRAK technology and single-transaction-translator operation to manage mixed-speed USB traffic efficiently. Its integrated management interface supports configuration over I2C, while port mapping provides control over downstream-port relationships.

The Microchip USB2513B-AEZC is a 3-port USB 2.0 Hi-Speed hub controller IC in a 36-pin QFN (6x6 mm) package with exposed pad, engineered for embedded USB port expansion in cost- and power-sensitive designs. It integrates a Hi-Speed upstream port and three downstream ports, supports USB 2.0 Link Power Management, and operates from a single 3.3 V supply. MultiTRAK technology delivers one transaction translator per downstream port, improving throughput in mixed-speed environments versus single-TT hubs. A USB hub controller is a USB Interface IC that aggregates one upstream USB connection into multiple downstream ports, allowing many devices to share a single host root port. Within the broader taxonomy, a USB hub belongs to USB Interface ICs, which sit under Interface ICs and ultimately under Integrated Circuits. The USB2513B-AEZC implements the hub repeater and transaction-translator functions defined by the USB 2.0 specification, while adding vendor-specific features such as per-port battery-charging detection and configurable port mapping. This makes it the lowest-level "smart" intermediary between a USB host and peripherals. Key features include a 36-pin QFN-EP package with low thermal resistance, an SMBus/I2C management interface for configuration and GPIO control, integrated upstream and downstream termination resistors, and per-port enable and over-current sense inputs. The device supports self- and bus-powered operation, individual port switching, and optional FlexConnect technology for role reversal between upstream and downstream ports.

Microchip Technology USB2513B-I/M2 is a 3-port USB 2.0 high-speed hub controller in a 36-SQFN 6x6 mm package. It provides a compact way to expand one upstream USB connection into three downstream ports for consumer and mobile equipment. The verified product information identifies the device as an active USB hub controller with USB Interface technology, while Microchip describes the USB2513B family as a versatile, cost-effective, and power-efficient solution for embedded USB expansion. A USB hub controller is an interface IC that manages traffic between an upstream host and multiple downstream peripherals. Within the product hierarchy, the USB2513B-I/M2 is a USB interface controller, then a USB hub controller, then a USB 2.0 high-speed device, and finally a semiconductor. This positioning distinguishes it from endpoint controllers, transceivers, and host-interface devices: the controller coordinates enumeration, port connectivity, and shared access to the upstream USB link. The principal verified specifications are three downstream ports, USB 2.0 high-speed operation, and a 36-SQFN package measuring 6x6 mm. Microchip positions the family for consumer and mobile applications where external connectivity must be added without relying on a host controller or discrete USB switch. Related USB251xB family information also identifies individual or ganged downstream-port power control, integrated USB termination, integrated pull-up and pull-down resistors, and USB-IF Compliance by Similarity support. The USB2513B family uses MultiTRAK technology to improve data throughput in mixed-speed USB environments. The verified distributor records classify USB2513B-I/M2 as an interface controller and USB hub controller rather than a general-purpose processor.

The controller supports I²C EEPROM and SMBus host interfaces and is designed for embedded USB port expansion in consumer and mobile equipment. A USB hub controller is a semiconductor that manages traffic between a USB host and one or more downstream USB ports. The USB2513BI family combines configurable USB 2.0 routing, low-power operation, and MultiTRAK transaction handling in one controller. Its position within the hierarchy is USB interface controller → USB hub controller → embedded USB interface IC, allowing one upstream connection to expand into multiple downstream ports. Three principal characteristics define the USB2513BI-AEZG: three USB 2.0 high-speed ports, a 3 V to 3.6 V supply range, and a 36-QFN 6 mm × 6 mm package. The family description also identifies configurable operation, low power consumption, and MultiTRAK technology for mixed-speed USB environments. These characteristics make the controller appropriate where a host interface must support several peripherals without using a full-size host computer. The MultiTRAK architecture is significant because it supports predictable handling of multiple USB transactions through the hub. Compared with basic four-wire hub implementations, a dedicated USB 2.0 controller can integrate device enumeration, configuration, status monitoring, and downstream-port management. The I²C EEPROM interface permits external configuration storage, while the SMBus interface provides a two-wire management path suitable for embedded platform control and diagnostics. Typical uses include compact consumer hubs, mobile accessories, embedded USB expansion, docking systems, and mixed-speed peripheral arrangements. In a docking application, the upstream USB connection can feed multiple external peripherals while the controller manages enumeration and port transactions. In a mobile accessory, the low-power 3.3 V-class operating range and compact QFN footprint help limit board area, although final thermal and power performance depend on the complete system implementation. Designers should preserve the manufacturer's recommended external-component and layout arrangement around the controller. The I²C EEPROM interface, USB data routing, power-supply connections, and decoupling network must be implemented according to the device pin description and reference circuitry. The package has 36 terminals, so use the 36-pin QFN pinout rather than a generic 32-pin or 40-pin footprint when assigning PCB pads and checking continuity. This page combines the manufacturer's product description, USB family characteristics, package information, interface details, and application-oriented engineering guidance. It also separates confirmed direct alternatives from broader family comparisons, helping engineers identify the correct USB hub controller and verify footprint, port count, supply range, and configuration requirements before committing a PCB layout.

Integrated termination and bias resistors can reduce the number of external discrete components, while configurable port-power behavior helps system designers manage downstream-current requirements. Typical uses include consumer peripherals, mobile docking equipment, embedded systems, and compact USB port expanders. A system requiring three USB 2.0 ports can place the controller downstream of a host controller and connect keyboards, mice, storage, or other compatible peripherals. Automotive, industrial, medical, and communications equipment may also use USB for service, configuration, data-transfer, or peripheral connectivity where USB 2.0 compatibility is sufficient. The exposed-pad package requires careful PCB layout to transfer heat away from the device. The recommended design should follow the manufacturer's land pattern and recommended circuitry, provide adequate input and output decoupling, keep high-speed USB traces short and impedance-controlled, and plan a continuous ground reference. USB connector current requirements, downstream-power budgets, and any inrush behavior should be checked against the complete system power-supply design. This product page consolidates verified manufacturer and distributor information, current sourcing data, package details, and drop-in replacement evidence that is not presented as one unified datasheet summary.
