CY8CLED02-8SXI

CY8CLED02-8SXI - 24MHz 2-Channel LED Controller | Infineon

The Infineon Technologies CY8CLED02-8SXI is an M8C EZ-Color HB application-specific LED-controller microcontroller with 4KB of programmable flash, 256 x 8 RAM, six I/O pins, a 24 MHz internal oscillator, and an 8-SOIC package. It controls two independent LED channels through configurable dimmers, with 32-bit resolution per channel and dynamic reconfiguration. The device is positioned as a compact system-on-chip solution for high-brightness LED lighting rather than a general-purpose MCU. An application-specific LED-controller microcontroller is a specialized embedded-control IC that integrates programmable logic, memory, digital I/O, and LED-control functions on one die. In the product hierarchy, the CY8CLED02-8SXI belongs to microcontrollers, specifically the EZ-Color HB LED-controller family. Its role is to execute dimming and lighting-control firmware, manage LED-channel outputs, and reduce the external circuitry needed for dedicated high-brightness lighting systems. The verified specifications identify 4KB (4K x 8) of program memory, 256 x 8 RAM, six I/O pins, 24 MHz operation, an internal oscillator, and an 8-SOIC package measuring 0.154 inch, or 3.90 mm, in width. The LED-control feature set includes configurable dimmers for two independent channels, 32-bit resolution for each channel, dynamic reconfiguration, and binning compensation. These capabilities make firmware-defined behavior central to the device's value. The M8C architecture combines embedded program and data memory with six external I/O in a small surface-mount package. A 24 MHz internal clock eliminates the need for an external oscillator when the system design permits operation from the specified internal time base. The 4KB program-memory limit is the principal firmware constraint, so control code should be compact and lighting effects should be selected for repeatability rather than elaborate computation. Typical uses include high-brightness LED modules, decorative color lighting, fixed architectural accents, display backlighting, compact lamp controllers, and two-channel illumination products where independent dimming is useful. The controller is particularly appropriate when both channels must share an embedded control program but require separate dimming commands. Final electrical suitability still depends on the LED topology, drive current, supply limits, and dimming behavior defined in the manufacturer datasheet. Designers should preserve the SOIC-8 land pattern and route decoupling close to the supply pins. Because the verified excerpts do not provide complete pin names, voltage limits, timing values, or output-drive details, those items must be checked in the manufacturer datasheet before schematic sign-off. LED current should not be inferred from the MCU I/O ratings without the missing electrical data. This page consolidates verified distributor specifications, package information, feature descriptions, sourcing links, and engineering-oriented usage guidance. It also distinguishes confirmed data from parameters that still require verification, providing a useful starting point for LED-controller design while avoiding unsupported electrical assumptions.

Typical end-use scenarios for the CYUSB3013-BZXC include USB 3.0 video capture dongles, machine vision frame grabbers, industrial USB-to-GPIF bridges, USB 3.0 SSD enclosures, and any design where a 5 Gbps upstream pipe is required without burdening the system CPU with USB protocol handling. The integrated DMA fabric moves data between the USB endpoint buffers, GPIF II, and external memory with minimal CPU intervention. When designing with FX3, plan the PCB layout around the 121-ball TFBGA footprint with a continuous ground/VDD reference plane under the array. Decoupling must include bulk 4.7 uF plus 0.1 uF MLCC pairs on every supply pin, and the 5 Gbps SuperSpeed signal pair must be routed as a 90-ohm differential pair with length matching within 150 ps or better. Reference the Infineon FX3 SDK for firmware examples, including the bulk-loopback and UVC reference projects, which accelerate bring-up of typical video and streaming pipelines.

CYUSB3302-68LTXIT

CYUSB3302-68LTXIT - HX3 USB 3.0 Hub Controller | Infineon

The Infineon CYUSB3302-68LTXIT is a USB 3.0 SuperSpeed hub controller from the HX3 family, integrating an ARM Cortex-M0 microcontroller core with 32 kB of ROM in a 68-pin VFQFN Exposed Pad package. It supports four downstream ports operating at Low-Speed, Full-Speed, Hi-Speed, and SuperSpeed (5 Gbps) and is designed for both embedded and standalone USB hub applications including battery-charging downstream ports. The 'T' suffix denotes tape-and-reel packaging for high-volume assembly, while the 'I' suffix indicates the industrial temperature grade. A USB 3.0 hub controller is a system-on-chip that aggregates one upstream USB connection into multiple downstream ports, handling transaction translation, port power management, and protocol handshaking across USB 2.0 and USB 3.0 link layers. Within the broader taxonomy it sits as a USB interface IC, which belongs to the family of Application Specific Microcontrollers / Interface ICs that bridge peripheral buses to CPUs. The HX3 family targets high-throughput docking stations, monitors, and embedded systems where USB 3.0 bandwidth is required without external PHY complexity. Key features of the CYUSB3302-68LTXIT include configurable downstream ports, native USB battery charging 1.2 support, integrated 5 Gbps PHY, low-power states per USB 3.0 specification revision 1.0, and ARM Cortex-M0 firmware that the OEM can optionally customize. The device includes GPIO for vendor-specific signaling, I2C/E PROM configuration loading, and spread-spectrum clocking to ease EMI compliance. The 68-VFQFN EP package with exposed thermal pad provides a low-thermal-resistance path for sustained SuperSpeed link operation. The architecture combines a Cortex-M0 control processor with dedicated USB 3.0 and USB 2.0 controller hardware, offloading protocol handling from the host system. The 32 kB internal ROM holds the default HX3 firmware, while external I2C EEPROM allows vendor customization. USB 3.0 specification revision 1.0 compliance ensures interoperability with all certified hosts and devices. Typical applications include USB 3.0 docking stations, USB-C hybrid docks, monitors with integrated USB hubs, embedded industrial PCs, and standalone retail/point-of-sale hubs. Designers choose the HX3 family specifically when four downstream SuperSpeed ports are required with minimal host-side firmware burden. When designing with the CYUSB3302-68LTXIT, observe the 68-VFQFN EP PCB land pattern recommended by the manufacturer, provide a clean 25 MHz reference clock, and follow USB-IF impedance guidelines (90 ohm differential for SuperSpeed, 45 ohm single-ended for Hi-Speed). Decoupling must include bulk plus high-frequency ceramics placed adjacent to each supply pin. This page synthesizes distributor pricing, same-package drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, giving procurement and design engineers a single reference for the CYUSB3302-68LTXIT.

CYUSB3328-88LTXC

CYUSB3328-88LTXC - HX3 USB 5 Gbps Hub Controller | Infineon

The Infineon CYUSB3328-88LTXC is an EZ-USB HX3 USB 3.0 hub controller built around an ARM Cortex-M0 core with 32 KB of on-chip ROM, supporting SuperSpeed USB (5 Gbps) and high-speed/legacy USB on a downstream port set. Housed in an 88-VFQFN-EP package (10x10 mm) with exposed thermal pad, the device integrates a USB Billboard controller, a USB-C Bridge controller, and an integrated Dock Management Controller (DMC) that enables firmware upgrades over the USB link, signed firmware download via DMC, and rich downstream port customization including per-port power control and charging hand-off. A USB 3.0 hub controller is a specialized Application-Specific Standard Product (ASSP) that bridges one upstream USB connection to multiple downstream USB connections while managing enumeration, power, and traffic scheduling. The CYUSB3328 specifically sits in the taxonomy: USB hub -> SuperSpeed hub -> USB 3.0 hub controller -> mixed-signal ASSP -> semiconductor. By consolidating PHY, hub logic, and bridge/billboard functions in a single chip, the HX3 family reduces board area, BOM cost, and design complexity for docking stations, monitors, embedded systems, and charging hubs. The 5 Gbps SuperSpeed datapath is critical because USB 3.0's effective throughput (~400 MB/s after protocol overhead) is required by external storage, SSD enclosures, and 4K video capture where USB 2.0 would bottleneck. Key features include 5 Gbps SuperSpeed USB 3.0 with backward-compatible USB 2.0/1.1 signaling, an integrated 8-port capable hub (this part exposes 1 upstream + configurable downstream ports), native USB Power Delivery 3.0, Battery Charging v1.2 (BC v1.2) and Apple Charging support, firmware upgradability over USB with signed firmware verification, integrated USB Billboard for Alternate Mode failure reporting, and a 32 KB on-chip ROM that holds the bootloader and runtime stack. The part operates from a single 3.3 V supply and provides GPIO for port indicators and VBUS control. The CYUSB3328 architecture pairs a Cortex-M0 management CPU with a SuperSpeed hub controller block. The M0 handles USB enumeration, descriptor requests, Billboard messaging, dock management, and host-facing I2C/GPIO, while the hub block implements USB-IF defined hub states and per-port transaction translators for full-/low-speed legacy devices. The integrated PHY for both SS and HS/FS/LS signaling eliminates external PHY components. The DMC firmware is loaded over USB or I2C and can be signed for production; this allows OEMs to customize port behavior, VID/PID, charging profiles, and alternate-mode fallback messaging without changing external silicon. Typical applications include USB Type-C docking stations, USB 3.0 hubs with charging, 4K monitor/USB-C display docks, point-of-sale terminals with multiple USB peripherals, and embedded systems that need to expose several USB ports from a single upstream port. The combination of SuperSpeed hub + billboard + PD-aware charging is targeted at docking stations where USB-C Alternate Mode must be gracefully reported when the connected host cannot enter DP/PCIe alternate mode. Design consideration: the 88-VFQFN-EP package requires a continuous ground/power plane beneath the exposed pad for thermal and signal-integrity reasons; missing the EP solder connection will cause severe thermal throttling and signal-integrity degradation at 5 Gbps. Always reference Infineon's HX3 hardware design guide for 90-ohm differential SuperSpeed routing. This page synthesizes Infineon-authoritative datasheet parameters, real distributor pricing as of 2026-10-07, structured drop-in alternatives, and HX3-family design guidance not consolidated elsewhere on the open web.
