UJA1169ATK/F/3Z - Mini HS-CAN SBC with 3.3V LDO | NXP
The NXP UJA1169ATK/F/3Z is a mini high-speed CAN System Basis Chip (SBC) that integrates an ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 compliant HS-CAN transceiver supporting CAN FD up to 5 Mbit/s, alongside an onboard 3.3 V microcontroller supply (V1) and a second 5 V onboard LDO (V2), both rated at 250 mA, in a 20-pin HVSON (3.5x5.5 mm) package with exposed thermal pad. An SBC is an integrated automotive network IC that combines a CAN (Controller Area Network) physical-layer transceiver with one or more voltage regulators and supporting features such as watchdog, wake-up management, and fail-safe output control. The SBC sits between the vehicle battery (VBAT) and the microcontroller, providing a regulated supply while the HS-CAN transceiver links the host MCU to the in-vehicle CAN bus. This class of device collapses what would otherwise be several discrete ICs into a single package, reducing PCB area, BOM cost, and quiescent-current budget in body, chassis, and powertrain ECUs. Key specifications of the UJA1169ATK/F/3Z include: 3.3 V V1 LDO with 250 mA current capability, 5 V V2 LDO at 250 mA for the internal transceiver and additional onboard hardware, CAN FD data rates up to 5 Mbit/s, very low VBAT quiescent current in standby modes, and integrated fail-safe behavior with a watchdog and SPI control. The /3 suffix on this variant fixes V1 at 3.3 V rather than the 5 V used in the UJA1169ATK, UJA1169ATK/F, UJA1169ATK/X, and UJA1169ATK/X/F members of the family. The /F suffix indicates the SPI-gated watchdog configuration; the trailing Z designates the 13-inch reel SBB packing format. Architecturally, the UJA1169ATK/F/3Z pairs a high-speed CAN physical layer with two linear regulators sharing a common thermal pad. The HVSON-20 exposed-pad package keeps thermal resistance low so both regulators can sustain full 250 mA loads simultaneously, while the integrated CAN transceiver implements the ISO 11898-2:2016 standard and supports the SAE J2284 series bit-timing benchmarks used by global automakers. The device supports selective wake-up and several low-power modes that allow an ECU to drop to microamp-level quiescent draw when the bus is idle. Typical automotive applications include body control modules, gateway ECUs, sensor cluster nodes, HVAC controllers, comfort and convenience modules, and small powertrain controllers. The 3.3 V LDO mapping of the /3 variant makes the device a direct fit for low-voltage host microcontrollers such as the NXP S32K1xx family that operate from a 3.3 V rail. When laying out the PCB, place decoupling capacitors directly at V1 and V2 with short, wide ground returns, and attach the exposed thermal pad to a copper plane sized for the worst-case dissipation. Use a 13-inch reel handling process consistent with the Z suffix to integrate this part into high-volume surface-mount lines. This page synthesizes distributor pricing, drop-in alternative selection, and practical SBC design notes not found in the manufacturer datasheet.
UJA1169ATKZ - Mini HS-CAN SBC, 5V/3.3V LDO 250mA | NXP
The NXP UJA1169ATKZ is a mini high-speed CAN System Basis Chip (SBC) integrating an ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 compliant HS-CAN transceiver with CAN FD support up to 5 Mbit/s, plus an integrated 5 V or 3.3 V, 250 mA voltage regulator (V1) for a host microcontroller or peripheral loads, all housed in a 20-pin HVSON (3.5 x 5.5 mm) exposed-pad package. It targets compact automotive body and network applications where PCB area, BOM count, and quiescent current are critical, and where a clean CAN bus interface plus a small, protected supply rail must coexist with a serial peripheral interface (SPI) control channel and independent watchdog. A System Basis Chip (SBC) is a category of automotive networking IC that combines a physical-layer transceiver with on-chip power, supervision, and diagnostic functions into a single die. Within the broader hierarchy, SBCs sit between standalone CAN transceivers (which provide only the bus interface) and full ECU power-management companions (PMICs), allowing one part to replace what traditionally required three or four discrete devices. The UJA1169 family achieves this by merging an HS-CAN physical layer with a low-drop linear regulator, a watchdog, an SPI configuration port, and a LIMP output for fail-safe system behavior. Key features include CAN FD support up to 5 Mbit/s for modern in-vehicle networking bandwidth, integrated 250 mA LDO selectable between 3.3 V and 5 V to host an MCU without an external regulator, very low quiescent current in standby modes for permanently connected nodes, integrated watchdog with window or timeout behavior, SPI for control and status, and a LIMP pin for graceful system degradation. The HVSON-20 exposed pad provides a low thermal resistance path suitable for harsh automotive environments. Architecturally, the device uses a mixed-signal BiCMOS process: the CAN transceiver meets ISO 11898-2:2016 (and the upcoming merged ISO 11898-2/5/6 standard for selective wake-up and CAN FD), while the regulator is implemented as a high-side series pass element with reverse-polarity and load-dump protection suitable for 12 V automotive battery rails. Battery/supply voltage can reach 28 V (with load-dump transient tolerance typical for 12 V systems). Typical applications include automotive body control modules (BCMs), gateway and CAN nodes requiring a regulated MCU rail, network sensors and actuators, HVAC controllers, seat/door/zone modules, and anywhere an HS-CAN node with integrated microcontroller power is needed to shrink the BOM. When designing with this part, derate the 250 mA regulator headroom against the V1 voltage tolerance, since a 12 V battery input powering a 5 V, 200 mA MCU load dissipates roughly 1.4 W in the package. Sufficient copper area on the exposed pad is recommended to keep the junction within the automotive temperature range. This page synthesizes NXP distributor pricing, qualified drop-in alternative cross-references, and practical automotive-node design notes that go beyond the manufacturer datasheet itself.
UM9921 - Microchip Technology | XAIPART
The Microchip Technology UM9921 is a component listed by Microchip Technology and distributed through authorized channels such as Arrow Electronics and indexed by Octopart, where it is categorized under the PIN (pin electronics / pin driver) product grouping. Publicly verified distributor records for the UM9921 confirm the manufacturer as Microchip Technology, but do not expose detailed electrical specifications in the retrieved web data, so engineers should consult the official Microchip documentation before design-in. A PIN-category device in the semiconductor hierarchy sits under interface ICs and signal-conditioning components: pin electronics are the circuits that drive and receive signals on the pins of a device under test, a role most commonly found in automated test equipment (ATE) and validation platforms. Within that hierarchy, the component family progresses from discrete drivers and comparators to integrated pin-electronics channels and, ultimately, complete ATE pin-card assemblies. Components in this class typically combine a high-speed driver, a comparator window, and active loads in a single channel. Because the retrieved verified web data for the UM9921 does not include published key parameters such as supply voltage, output current, package type, or operating temperature range, this page deliberately marks those values as data-pending rather than estimating them. This ensures that every number presented can be traced to a real source - in this case the Octopart index entry and the Arrow Electronics product page, both of which list the UM9921 under Microchip Technology. Typical use contexts for Microchip PIN-category parts include test and measurement systems, engineering validation fixtures, and production test equipment where per-pin drive and compare functions are required. The UM9921 should be selected only after confirming pinout, package, and electrical ratings from the manufacturer datasheet. Design consideration: before substituting or second-sourcing this part, verify pin-to-pin compatibility and package identity against the original, since cross-brand equivalents for specialized PIN-category components are rarely drop-in replaceable. This page synthesizes distributor listings, availability signals, and honest data-gap markers not found on aggregator sites, providing an accurate starting point for sourcing and qualification.
UPD72874GC-YEB-A - IEEE 1394a OHCI 1.1 PHY-Link Host Controller | Renesas
The Renesas UPD72874GC-YEB-A is a single-chip IEEE 1394a OHCI 1.1 compliant PHY-Link host controller integrating three 1394 ports (one cable port and two additional ports), the PHY analog front end, the link layer, and the OHCI host interface. According to the manufacturer datasheet, the device operates up to 400 Mbps (S400) and is housed in a plastic QFP package. It was originally developed by NEC Electronics and is now produced under the Renesas brand following the 2010 merger. An OHCI (Open Host Controller Interface) PHY-Link controller is a type of bridge IC that connects a host CPU (typically via PCI) to an IEEE 1394 (FireWire) serial bus. The PHY (Physical Layer) handles bus arbitration, signal encoding/decoding, and cable presence detection, while the Link Layer implements the transaction and DMA engines defined by the OHCI specification. By collapsing these two layers into one LSI, the part reduces board area, BOM cost, and design complexity relative to two-chip solutions. Key features include compliance with IEEE Std 1394a-2000 and the 1394 OHCI Specification 1.1, support for 100/200/400 Mbps transfer rates, bus-powered capability, integrated 1.5 kV cable-port ESD protection (typical for the family), 3.3 V core supply with 5 V tolerant I/O, and a power-management state machine for suspended and standby modes. The host bus interface conforms to PCI 2.1 with a 32-bit data path at up to 33 MHz. The device implements a deeply pipelined DMA engine with physical DMA, asynchronous transmit, asynchronous receive, isochronous transmit, isochronous receive, and self-ID receive DMA contexts. Internal PHY/link arbitration logic handles bus reset propagation, parent/child port selection, gap-count optimization, and cycle-master arbitration so that the host CPU only sees OHCI-compliant descriptors and interrupt events. Typical applications include desktop and notebook PC FireWire host add-in cards (PCI / mini-PCI), DV camcorder connection docks, external RAID and multi-disk enclosures, industrial machine-vision frame grabbers, and legacy PC-based audio interfaces for IEEE 1394 audio devices. Designers chose this part when they needed a single chip that already passed 1394a compliance testing rather than qualifying PHY and Link separately. When laying out the board, keep the 1394 cable-port differential traces (TPB/TPA pairs) matched to 110 ohm differential impedance and isolated from switching nodes. Decouple each VCC pin with a 0.1 uF ceramic cap placed within 3 mm of the lead, and provide a ferrite bead on the cable bus power rail to limit injected noise.
USB20H04-JT - 4-Port USB 2.0 Hub Controller | SMSC
The SMSC USB20H04-JT is a four-port USB 2.0 hub controller with four downstream ports, four transaction translators, I2C, SMBus, and serial host interfaces, supplied in a 64-pin TQFP package measuring 10 mm by 10 mm. It supports operating-temperature conditions from 0°C to 70°C and accepts the verified 1.74 V to 2 V and 3 V to 3.6 V supply ranges. A USB hub controller is an interface semiconductor that manages traffic between one upstream USB host and multiple downstream devices. It belongs to the USB interface-controller hierarchy and coordinates attachment, enumeration, power management, and data transfer so that peripheral devices can share one host controller. The USB20H04-JT targets USB 2.0 hubs requiring multiple high-speed downstream ports. Four transaction translators are the device's principal architectural feature and help maximize USB throughput when devices on different downstream branches transfer data concurrently. The controller supports OTG-compatible USB devices and bus-powered Hi-Speed hub designs, making it useful in compact external hubs, docking stations, printers, storage systems, and embedded USB equipment. Its stated supply current is 135 mA, which must be included in hub power-budget calculations. The USB20H04-JT supports serial, I2C, and SMBus host-side connectivity, allowing firmware or an external controller to supervise hub behavior. Its lead-free construction and surface-mount format support automated PCB assembly, although the 64-pin TQFP package requires careful fanout and exposed-pad-free thermal review. The component is identified as CMOS and TQFP-64 in distributor records. For design work, route USB differential pairs as controlled-impedance, length-matched connections and keep supply decoupling close to the device. The verified material does not provide a complete pinout, electrical limits table, supported current budget, or detailed timing values in the supplied text, so those details must be verified in the manufacturer datasheet before schematic release or USB compliance testing. This product data consolidates verified distributor specifications, the identified USB2504 migration path, sourcing references, and practical design cautions. Engineers should treat the USB2504 family as a documented migration option, not as an automatically interchangeable replacement until package pinout, firmware, clock, power, and USB compliance requirements are checked.
USB2412-DZK - 2-Port USB 2.0 Hub Controller | Microchip
The Microchip USB2412-DZK is a low-power, two-port USB 2.0 hub controller IC using a single Transaction Translator architecture, with a 3 V to 3.6 V supply range and support for low-speed, full-speed, and high-speed downstream devices in a 28-QFN package. It is designed for embedded USB hub applications requiring two downstream ports and USB 2.0 Hi-Speed operation. A USB hub controller is an interface IC that manages traffic between one upstream USB host connection and multiple downstream USB ports. The USB2412 belongs to the USB interface-controller hierarchy, where USB 2.0 connectivity, transaction translation, port management, and embedded system integration combine into a dedicated hub solution. Its single Transaction Translator, or STT, architecture is intended to reduce implementation complexity in compact USB hub designs. The verified product information identifies two downstream ports, USB 2.0 operation, low-power operation, and support for low-speed, full-speed, and high-speed downstream devices when the hub operates at high speed. The controller is available in a 28-QFN package, while distributor records identify the package as 28-VFQFN with an exposed pad. The USB interface supports system integration with embedded USB host, peripheral, docking, and industrial equipment designs. The 3 V to 3.6 V operating supply range places the device in a low-voltage digital interface class. USB data integrity depends on correct PCB routing, adequate power distribution, compliant connector implementation, and proper decoupling. The exposed-pad package requires attention to thermal and layout practices, even though the verified snippets do not provide a complete electrical limit table or detailed power-consumption values. Typical applications include two-port embedded USB hubs, self-powered USB equipment, industrial control systems, test and measurement fixtures, docking equipment, and compact host systems that need USB device expansion. The two-port architecture is useful when a system must connect peripherals without adding multiple independent host controllers. When selecting a replacement, verify the complete pinout, package dimensions, exposed-pad connection, USB signal routing, clock requirements, and power sequencing against the original design. The USB2412-DZK-TR is a tape-and-reel ordering variant, while other listed controllers or transceivers may provide different functions and must not be treated as drop-in substitutes without manufacturer verification. This page consolidates the verified manufacturer description, distributor package data, official datasheet link, application guidance, and cross-reference findings to support engineering selection. It distinguishes confirmed USB2412 attributes from parameters that require the manufacturer datasheet or an authorized design review.
USB2422-CP - Low-Power 2-Port USB 2.0 Hub Controller | Microchip Technology
The Microchip Technology USB2422-CP is a low-power, single-transaction-translator USB 2.0 hub controller with two downstream ports, packaged in a 24-QFN (4x4 mm) package. It supports an upstream Hi-Speed and Full-Speed hub connection or a Full-Speed-only configuration, while downstream devices can operate at Low-Speed, Full-Speed, or Hi-Speed when configured as a Hi-Speed hub. The controller is designed for embedded USB expansion systems requiring compact bus routing and USB 2.0 compatibility. Its two-port architecture integrates downstream-port USB connectivity into one controller rather than requiring separate hub devices. A USB hub controller is an interface IC within the broader USB interface-controller and semiconductor hierarchy. In an embedded system, the upstream port connects the hub to a host controller, while each downstream port connects external peripherals such as storage, keyboards, communications modules, or service interfaces. USB2422-CP acts as the transaction translator and hub-management element between those connections, helping the host system organize USB traffic across two ports. Its support for Full-Speed and Hi-Speed operation makes it relevant to legacy USB 2.0 embedded designs rather than modern USB 3.x or USB4 systems. The principal verified feature set includes a 2-port USB 2.0 hub configuration, single transaction translator operation, upstream Hi-Speed and Full-Speed attachment capability, and downstream Low-Speed, Full-Speed, and Hi-Speed support. Microchip describes the device as low power, which is valuable in embedded equipment where USB expansion must not dominate the system power budget. The 24-QFN package provides a compact surface-mount footprint, but its exposed thermal and electrical requirements must be handled according to the manufacturer datasheet. The controller is positioned between a USB host and downstream USB peripherals. When configured as a Hi-Speed hub, the upstream link and compatible downstream links can use USB 2.0 Hi-Speed operation; when used as a Full-Speed-only hub, the design avoids requiring Hi-Speed operation. Device attachment, removal, enumeration, and power-management behavior must be evaluated against the USB host software and the electrical requirements of the connected peripherals. The verified web data does not provide current unit pricing, stock status, lead time, detailed pin names, or all electrical timing and current limits, so those values are not inferred here. Typical applications include embedded instrumentation, industrial control panels, compact USB expansion boards, peripheral consolidation, and USB connectivity in systems that already use a USB 2.0 host controller. A hub may be useful when a processor exposes one host port but the enclosure requires two external connections. The design should verify connector protection, power switching, cable length, chassis grounding, and host compatibility. The manufacturer datasheet is the authoritative source for pin assignments, electrical limits, configuration registers, and implementation details. Use the USB2422-CP when the existing PCB is designed around its 24-QFN footprint and the application needs a compact two-port USB 2.0 hub controller. Confirm package pin compatibility, operating conditions, and USB host requirements before treating any substitute as a drop-in replacement. This page combines verified manufacturer descriptions, distributor package information, datasheet references, application context, and procurement guidance. It distinguishes documented facts from missing parameters and avoids inventing prices, pin assignments, electrical limits, or replacement parts.
USB2422-I/MJ - 2-Port USB 2.0 Hub Controller | Microchip
The Microchip Technology USB2422-I/MJ is a low-power, single-transaction-translator USB 2.0 hub controller with two downstream ports, 3.3 V operation, and a 24-QFN 4x4 mm package. It supports Low-Speed, Full-Speed, and Hi-Speed downstream devices when configured as a Hi-Speed hub, while the upstream connection can operate as a Hi-Speed and Full-Speed hub or as a Full-Speed-only hub. A USB hub controller is an interface IC that manages one upstream USB connection and multiple downstream USB ports. Within the broader hierarchy of USB interface controllers, the USB2422 combines port routing, power-switch control, overcurrent protection, internal voltage regulation, and USB signal conditioning in one compact device for embedded systems. The part includes BC1.1 protocol support, downstream port power-switch control, overcurrent protection, an internal regulator, and ESD protection. Required USB port resistors are integrated, including D+ and D- series-termination resistors and the specified pull-down or pull-up resistors. Internal pull-ups are also provided for downstream overcurrent-sense inputs, reducing external component count. Its single-translation-translator architecture serves embedded USB applications in which low power, compactness, and upstream-device integration matter more than independent simultaneous translation on every downstream port. The device can therefore support compact host ports in equipment that otherwise lacks native USB hub routing. Typical uses include industrial control panels, medical equipment, printers, embedded test systems, set-top boxes, and other USB 2.0 equipment requiring two downstream connections. Applications should account for the hub's single-translator architecture and verify downstream-device compatibility before final system release. PCB implementation should preserve the manufacturer's recommended USB trace geometry, place decoupling and support components near their associated pins, and route differential D+ and D- paths as a matched pair. USB signal integrity depends on controlled impedance, minimized stubs, and uninterrupted return-path continuity across the connector, controller, and protection circuitry.
USB2422/MJ - 2-Port USB 2.0 Hub Controller | Microchip
The Microchip Technology USB2422/MJ is a low-power, single-transaction-translator, two-port USB 2.0 hub controller for embedded USB solutions. It supports one upstream port and two downstream ports in a 24-QFN package measuring 4 mm by 4 mm. The controller can operate as a Hi-Speed and Full-Speed hub or as a Full-Speed-only hub, while downstream devices may use Low-Speed, Full-Speed, or Hi-Speed when the hub is configured for Hi-Speed operation. A USB hub controller is an interface integrated circuit that manages traffic between one upstream USB host connection and multiple downstream ports. Within the USB interface hierarchy, it belongs to the class of USB controllers and hub-controller devices used to expand USB connectivity in embedded systems. Unlike a host-controller interface that directly manages a host bus, the USB2422/MJ translates USB traffic for attached downstream devices and centralizes hub functions. The verified product information identifies the USB2422 as a two-port USB 2.0 Hi-Speed hub controller. Microchip states that all required USB-port resistors are integrated, including the series termination resistors and the required pull-down and pull-up resistors on D+ and D- pins. The downstream-port over-current sense inputs also have internal pull-up resistors. These integrated functions can reduce external discrete-component count while simplifying PCB layout. The single-translation architecture is a key engineering distinction. It uses one transaction translator for the two downstream ports rather than assigning an independent translator to every port. This can be suitable for embedded USB expansion where the application does not require maximum simultaneous transaction concurrency. By contrast, Microchip identifies USB2512B as a Multiple Transaction Translator design for applications needing more performance or parallel downstream-port operation. Typical uses include embedded instrumentation, industrial control equipment, printers, test systems, set-top equipment, and other USB-enabled products that need two downstream connections from one embedded host interface. The exact upstream and downstream interface rates, electrical limits, pin names, clock requirements, and operating-temperature details must be confirmed in the manufacturer datasheet before layout or firmware development. For robust implementation, follow the USB2422 Hardware Design Checklist and preserve the required USB routing, termination, bypass, and grounding practices. The 24-QFN footprint also demands careful thermal-pad assembly and adequate exposed-pad copper. Because the supplied distributor snippets do not provide a complete pinout, this record avoids inventing pin assignments and marks missing technical values explicitly where required. This page consolidates the verified Microchip product description, distributor listings, datasheet links, and hardware-design references. It also distinguishes a true package-compatible replacement from merely similar USB hub controllers, which is essential because USB hubs may differ in translator architecture, pinout, package, clocking, and host-interface requirements.
USB2422T/MJ - 2-Port USB 2.0 Hub Controller | Microchip
The Microchip Technology USB2422T/MJ is a low-power, two-port USB 2.0 hub controller with a single transaction translator, designed for embedded USB hub implementations. It supports High-Speed and Full-Speed operation on the upstream side, while downstream devices can operate at Low-Speed, Full-Speed, or High-Speed when the hub is configured for High-Speed operation. The device is supplied in a 24-QFN 4 x 4 mm package. A USB hub controller is an interface IC that manages traffic between an upstream host and multiple downstream USB peripherals. The USB2422 combines the physical-layer connectivity, port management, transaction translation, and hub-specific control functions required to expand one host USB port into two downstream ports. It belongs to the USB interface controller hierarchy, which sits within interface ICs and broader embedded semiconductor systems. The controller integrates the required USB port resistors, including series termination resistors on D+ and D-, pull-down and pull-up resistors on D+ and D-, and internal pull-ups for the downstream over-current sense inputs. This integration reduces external discrete-component count and simplifies embedded hub-board layouts. The upstream interface can operate as a High-Speed and Full-Speed hub or as a Full-Speed-only hub, providing configuration flexibility for different host links and legacy peripherals. Microchip specifies conformance with the SMBus 1.0 voltage, power, and timing characteristics for slave-only devices except where Section 4.3 specifies otherwise. This makes the controller relevant to managed USB connectivity designs that use SMBus sideband signaling. Its two downstream ports are intended for embedded docking stations, compact equipment, industrial panels, and other USB expansion systems where external discrete hub electronics would add complexity. Typical applications include USB-to-USB port expansion, embedded test and measurement equipment, industrial control panels, media appliances, and compact host systems. The 4 x 4 mm QFN package supports space-constrained designs, but exposed-pad layout and thermal management must follow the manufacturer's recommended land pattern. When designing with the USB2422T/MJ, preserve the D+ and D- geometry, provide the required USB connection and bypass components, and use the package's exposed thermal pad as a low-impedance ground and heat-spreading path. Verify upstream and downstream operating-mode configuration, suspend behavior, and over-current handling in the complete system rather than assuming standard desktop-hub behavior. This page consolidates the verified manufacturer and distributor information, explains the USB2422's integration benefits, identifies practical design constraints, and separates confirmed drop-in alternatives from candidates that require footprint verification before substitution.
USB2502-AEY - 2-Port USB 2.0 Hub Controller | SMSC
The SMSC USB2502-AEY is a 2-port USB 2.0 hub controller that connects one upstream host port to two downstream-facing USB ports. The verified product material identifies support for Low-Speed operation at 1.5 Mb/s and Full-Speed operation at 12 Mb/s; when attached to a High-Speed host, both downstream ports can also support High-Speed operation at 480 Mb/s. It is available in a QFN package. A USB hub controller is an interface semiconductor within the broader USB interface-controller hierarchy. Its function is to manage traffic from one USB host connection across multiple downstream ports while supporting the speed modes permitted by USB 2.0. Configuration can be handled through strapping options, an external EEPROM, or a microcontroller interface; with a microcontroller, the hub operates as an SMBus slave device. The principal engineering benefits are its two-port integration, upstream Full-Speed or High-Speed attachment, and configurable setup. Downstream devices may operate at Low-Speed, Full-Speed, or High-Speed when the hub is attached to a High-Speed host. This allows one controller to serve keyboards, storage, communications adapters, and other USB peripherals without requiring separate upstream controllers. Technical implementation requires careful treatment of USB signal integrity, power distribution, grounding, and enumeration. The controller coordinates device attachment and port behavior, but the final system must still meet USB 2.0 layout, capacitance, and power requirements. Exact electrical limits, pin assignments, clock requirements, and package dimensions must be taken from the Microchip manufacturer datasheet rather than inferred from marketplace listings. Typical uses include compact USB hubs, embedded host systems, docking equipment, peripheral expanders, and industrial adapters. In these systems, USB2502-AEY provides the multi-port coordination logic while external power switches, connectors, crystal or clock circuitry, and supporting passives implement the physical USB interface. Exact bill-of-material requirements should be confirmed against the datasheet reference implementation. For USB hub layouts, keep high-speed traces short and controlled, provide continuous return paths, place required decoupling close to the device, and validate differential impedance and connector placement in the assembled board. The available data does not state the package pin count, operating-temperature range, voltage limits, or full ordering-code characteristics, so those values must not be guessed.
USB2502-HD - 2-Port USB 2.0 Hub Controller | Microchip
The Microchip USB2502-HD is a two-port USB 2.0 hub controller that complies with the Universal Serial Bus Specification Revision 2.0 and operates as a full-speed hub or a full-/high-speed hub. Its two enabled downstream ports support low-speed devices at 1.5 Mb/s, full-speed devices at 12 Mb/s, and high-speed devices at 480 Mb/s when operated with a high-speed host. It is packaged as an integrated circuit, but the verified sources do not specify the exact package variant or dimensions. A USB hub controller is an interface semiconductor that expands one host USB connection into multiple downstream ports. It belongs to the USB interface controller hierarchy, alongside transceivers, host controllers, and device controllers. The hub manages enumeration, port power, connect and disconnect events, and transaction routing while allowing multiple USB peripherals to share one upstream host port. The principal feature of USB2502-HD is support for two downstream-facing ports and USB 2.0 operation. Low-speed, full-speed, and high-speed device support provides compatibility with keyboards, mice, storage devices, printers, and other USB peripherals. The controller can attach to a full-speed host or a higher-speed host, with downstream high-speed operation available when the hub is connected in the required high-speed configuration. Technically, USB2502-HD integrates the hub-control function into a dedicated interface IC rather than requiring a general-purpose processor. According to the Microchip USB2502 datasheet, the device is fully compliant with the Universal Serial Bus Specification Revision 2.0 dated April 27, 2000, including the cited errata. The available verified data does not state operating voltage, clock frequency, transceiver current, temperature range, pin count, or package dimensions. Typical uses include USB expansion in embedded systems, industrial control equipment, test instruments, printers, storage enclosures, and computer peripherals. The two-port architecture is useful when one host port must connect to two accessories while retaining support for both legacy and high-speed USB devices. Existing board revisions should be checked against the manufacturer package drawings before layout reuse or substitution. The most important design consideration is that a hub is only one part of the USB channel design. Upstream and downstream routing, connector placement, power-supply capacity, decoupling, ground continuity, and USB signal-integrity layout can determine whether advertised 480 Mb/s operation is reliable. Use the complete Microchip datasheet and its reference circuit for component values, layout geometry, and validation requirements. This product page consolidates the verified USB2502-HD commercial information, USB speed capabilities, official datasheet link, and sourcing details. It does not invent unavailable electrical or package specifications, and it distinguishes verified USB behavior from values that still require datasheet confirmation.
USB2502-HT - 2-Port USB 2.0 Hub Controller | Microchip
The Microchip Technology USB2502-HT is a two-port USB 2.0 hub controller supporting low-speed, full-speed, and high-speed USB devices in a 48-pin TQFP package. According to Microchip's USB2502 data sheet, its two downstream-facing ports can operate at 1.5 Mb/s, 12 Mb/s, or 480 Mb/s when connected to a high-speed host. The controller is designed for systems that need to expand one USB host connection into two downstream USB ports while maintaining USB 2.0 specification compliance. A USB hub controller is an interface integrated circuit that manages traffic between an upstream host and multiple downstream ports. In the USB hierarchy, it belongs to the USB interface-controller class, the broader interface-IC category, and ultimately the semiconductor device hierarchy. The USB2502 is intended for computers, peripherals, embedded systems, industrial equipment, and other USB 2.0 host platforms that require downstream-port expansion. Key verified features include two downstream-facing USB ports, USB 2.0 specification compliance, operation with a high-speed host, and support for low-, full-, and high-speed devices. The Microchip data-sheet result identifies the device as a fully specification-compliant USB 2.0 2-port hub and states compliance with Universal Serial Bus Specification Revision 2.0 dated April 27, 2000, including the listed 12/7/2000 and 5/28/2002 errata. The verified distributor listing identifies the physical part as a 48-TQFP USB interface IC. The controller separates upstream host traffic from the two downstream links, allowing peripheral devices such as keyboards, storage devices, network adapters, and human-interface devices to share one USB host port. System designers must provide the required USB transceiver, clock, decoupling, connectivity, and external passives described by the manufacturer data sheet. The controller itself is not a power-management IC and has no SOA data in the supplied sources.

The device is fully compliant with the USB 2.0 specification and requires no firmware development, simplifying integration into embedded systems, docking stations, monitors, and multi-port consumer electronics. When attached to a USB high-speed host, the three downstream ports each support low-speed (1.5 Mb/s), full-speed (12 Mb/s), and high-speed (480 Mb/s) operation through dedicated transaction translators. A USB hub controller is a line/bus controller that expands a single upstream USB port into multiple downstream ports while handling protocol translation, power management, and device enumeration. The USB2503 belongs to the hub controller family, which sits within the broader USB interface IC category and the overall peripheral controller hierarchy. The device integrates a Transaction Translator (TT) per port using Microchip's MultiTRAK technology, which improves concurrent bandwidth by allowing multiple full-/low-speed devices to operate simultaneously without bandwidth contention. Key features include pin-selectable default configuration, optional EEPROM or SMBus microcontroller configuration, integrated 1.8 V core LDO, support for both bus-powered and self-powered modes, dynamic port-power switching, and per-port overcurrent detection. The 48-QFN-EP package provides an exposed thermal pad for enhanced heat dissipation and a 0.5 mm pitch for compact PCB layout. The device operates from 3.0 V to 3.6 V and supports a 0 °C to 70 °C commercial temperature range.

USB2504-JT USB 2.0 4-Port Hub Controller | Microchip
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.
USB2504A-JT - USB 2.0 4-Port Hub Controller | Microchip
The Microchip Technology USB2504A-JT is a USB 2.0 four-port hub controller supporting high-speed 480 Mbit/s, full-speed 12 Mbit/s, and low-speed 1.5 Mbit/s devices. It is supplied in a 64-pin TQFP package measuring 10 mm by 10 mm and operates from a 3 V to 3.6 V supply. A USB hub controller is an interface IC that expands one upstream USB connection into multiple downstream ports while managing transaction translation, enumeration, power, and device connectivity. The USB2504A belongs to the USB interface-controller hierarchy, integrating USB 2.0 connectivity and four-port hub management into a single semiconductor device. The controller provides four transaction translators, one per downstream port, for independently handling supported USB traffic speeds. It supports per-port or ganged, selectable downstream power control and can detect whether the hub source is bus-powered or self-powered. 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 - 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.
USB2507-ADT USB 2.0 7-Port Hub Controller | Microchip
The Microchip Technology USB2507-ADT is an integrated USB 2.0-compatible seven-port hub controller with high-speed 480 Mbit/s, full-speed 12 Mbit/s, and low-speed 1.5 Mbit/s operation, housed in an 80-pin TQFP package measuring 12 x 12 mm. It provides one upstream host-facing connection and seven downstream USB ports, making it a practical interface controller for powered hubs, docking systems, industrial equipment, and multiport USB expansion. A USB hub controller is a semiconductor that manages traffic between one upstream USB host and multiple downstream peripherals. It belongs to the USB interface-controller hierarchy, which combines USB transaction translation, port management, clock recovery, power supervision, and device connectivity. The USB2507 is designed as a dedicated USB 2.0 hub rather than a general-purpose microcontroller, reducing the need for custom firmware and allowing compatible USB devices to share a host port. 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.
USB2512B-I/M2 - 2-Port USB 2.0 Hi-Speed Hub Controller | Microchip
The Microchip USB2512B-I/M2 is a 2-port USB 2.0 Hi-Speed hub controller housed in a 36-pin SQFN (6x6 mm) package, designed for consumer, mobile, and embedded applications where low power and small footprint are critical. It operates across a 3.0 V to 3.6 V supply range, supports USB 2.0 Hi-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) downstream signaling, and integrates Microchip's MultiTRAK™ (multi-transaction translator) technology with one transaction translator per downstream port for parallel traffic handling. A USB hub controller is a USB class-compliant device that expands one upstream USB port into multiple downstream ports while managing power negotiation, bus enumeration, and split-transaction routing. The hub sits in the broader USB controller hierarchy (USB 2.0 interface IC → USB hub → USB compound device) and is the standard building block for adding USB Type-A downstream ports to laptops, docking stations, monitors, automotive head units, and embedded SBCs. Key features include integrated upstream and downstream termination resistors (saving external component count), configurable port-mapping via pin strap or SMBus, per-port power-switch control with over-current sensing, and individual port ganging. The device supports battery-charging detection (BC 1.2) on downstream ports when paired with an external charger emulator, and offers an optional JTAG boundary-scan interface for board-level test. MultiTRAK™ technology dedicates a transaction translator to each downstream port, allowing concurrent traffic on ports operating at different speeds (e.g., a Full-Speed keyboard plus a Hi-Speed storage drive). Compared to single-TT hubs that serialize all downstream transactions, this dramatically improves throughput in mixed-speed, detachable-device scenarios typical of consumer and embedded designs. Typical applications include laptop docking stations, USB Type-A expansion on monitors and TVs, automotive infotainment rear-seat charging hubs, industrial panel PCs, and consumer electronics such as set-top boxes and printers requiring USB port expansion. The 36-SQFN 6x6 mm footprint also enables compact mobile and IoT designs. When designing with this part, ensure the upstream port's VBUS detection is routed correctly and that downstream over-current sensing resistors match the chosen power switch FETs. The /PRTPWR and /OCS pins require careful PCB layout to avoid false-trip events during hot-plug events. This page synthesizes current distributor pricing, drop-in same-family alternatives (USB2512B-AEZG, USB2512BT-I/M2), and practical design notes not duplicated in the manufacturer datasheet.

Typical applications include USB hubs in mobile accessories, consumer electronics, docking systems, portable equipment, and embedded USB peripherals. The two downstream ports can simplify connection of peripherals such as keyboards, storage devices, input controllers, or other USB-compatible accessories when the system power and enclosure allow it. The key design consideration is that USB hub implementation involves more than placing the controller on a PCB. Power-supply design, downstream-port overcurrent protection, USB signal routing, connector selection, firmware configuration, and compliance testing must be developed together. Review the manufacturer datasheet and evaluation-board documentation before finalizing a production layout. This page summarizes the verified manufacturer and distributor information, identifies the known application context, and separates confirmed data from specifications that still require confirmation in the datasheet or design documentation.
