CY7C65113C-SXCT Overview
A USB hub controller with an embedded microcontroller is a specialized application-specific semiconductor that combines USB connectivity, port control, and programmable device management. Within the broader hierarchy, this device belongs to microcontrollers, USB interface integrated circuits, interface ICs, and semiconductors. Its Harvard-architecture instruction set was optimized specifically for USB operations, while retaining applicability to non-USB embedded-control functions.
The principal feature is a full-speed USB hub integrated with a one-time-programmable 8-bit CPU. Verified source material identifies 8 KB of OTP program memory, four downstream-port support, 12 Mbps operation, a 6 MHz external clock, a 12 MHz internal CPU clock, and a 48 MHz internal hub clock. These parameters make it appropriate for compact USB hub, peripheral-control, and embedded USB-management designs where one device must perform both hub and local control functions.
The device uses a Harvard architecture, separating the program and data organizations to support USB-oriented execution. Its one-time-programmable memory fixes the implemented firmware at production programming time. This characteristic can simplify secure configuration for dedicated USB products, but it also means design changes may require another programmed part rather than a simple field firmware update.
Typical uses include four-port full-speed USB hubs, USB peripheral controllers, host-assisted downstream-port management, and compact embedded USB adapters. In a hub design, the downstream ports coordinate device attachment and enumeration, while the integrated microcontroller can manage board-specific functions. External USB transceivers, protection components, connectors, passives, and decoupling networks should be selected according to the system-level USB design requirements.
PCB layout should keep USB data routing short, controlled, and away from noisy switching nodes. Follow the manufacturer datasheet for package dimensions, pin assignments, clock connections, decoupling, and programming. The SXCT package is 28-pin SOIC, so its footprint must match a 28-pin gull-wing layout rather than a leadless package. Commercial sourcing data and the manufacturer datasheet should be reviewed before approving a new design.
This page consolidates verified distributor specifications, official-datasheet excerpts, package data, application guidance, and replacement-status analysis. Its practical value is that it distinguishes true device options from unsupported cross-reference results and highlights the OTP, clock, USB, and package constraints that most often determine design reuse.

Typical Applications
CY7C65113C-SXCT is suitable for 6 applications: Four-Port USB Hub Controller, USB Peripheral Management, Industrial USB-to-CAN Gateway, Legacy USB Expansion Card, USB Port Management Controller, USB Connectivity Test Fixture.
Four-Port USB Hub Controller
The CY7C65113C-SXCT fits a compact full-speed USB hub because it integrates an 8-bit OTP microcontroller with a 12 Mbps hub capable of supporting four downstream ports. Its 48 MHz internal hub clock and 12 MHz internal CPU clock provide dedicated timing domains for hub traffic and local control. In a hub board, the MCU can supervise attach, detach, configuration, and product-specific indicators while the USB hub logic handles downstream connectivity. The 28-pin SOIC package is easy to route on conventional through-hole-compatible PCB technology, although USB differential pairs still require short, impedance-controlled routing.
Recommended
USB Peripheral Management
The CY7C65113C-SXCT is suitable for embedded USB peripheral management because its instruction set was optimized for USB operations and its controller includes dedicated full-speed hub timing. At a 12 Mbps internal CPU clock, the device can combine USB-related control with board-level status handling, indicator logic, and interface supervision. The 8 KB OTP program memory makes it most appropriate when firmware can be fixed during production. Designers should define all required USB descriptors and peripheral behavior before programming because OTP prevents later in-field firmware revision.
Recommended
Industrial USB-to-CAN Gateway
The CY7C65113C-SXCT can serve as the local USB-facing controller in a compact USB-to-CAN gateway, where its 12 Mbps full-speed hub and OTP MCU simplify deterministic device configuration. The MCU can manage USB enumeration-facing functions, status LEDs, configuration constants, and communication supervision while an external CAN controller handles the field bus. The tradeoff is firmware permanence: the 8 KB OTP program memory requires careful partitioning and production planning, and the 28-pin SOIC needs clean grounding and protected I/O expansion.
Recommended
Legacy USB Expansion Card
The CY7C65113C-SXCT is a practical controller choice for a legacy PCI-to-USB expansion card that requires deterministic, production-fixed firmware. Its integrated full-speed USB hub reduces external controller count, while the internal hub and CPU clocks support separate timing needs. The 28-pin SOIC is useful where avoiding fine-pitch BGA assembly is important. System validation must still cover connector protection, power budgeting, enumeration behavior, host compatibility, and the fixed OTP firmware implications before production release.
Recommended
USB Port Management Controller
The CY7C65113C-SXCT fits centralized port supervision in a small USB distribution board because it combines four-downstream-port hub capability with programmable embedded control. It can support port-state decoding, board diagnostics, and fixed product behavior without separating those tasks across dedicated logic. The 48 MHz internal hub clock is especially relevant to USB traffic coordination, while the 12 MHz CPU clock supports control code. Engineers should budget external port-power switches and protection devices because the verified package describes hub and MCU functions, not complete downstream power delivery.
Recommended
USB Connectivity Test Fixture
The CY7C65113C-SXCT can support a low-cost USB connectivity test fixture when enumeration and downstream-port behavior must be checked by dedicated embedded logic. The OTP architecture makes it possible to store a repeatable test sequence for production fixtures, while the 12 Mbps full-speed hub provides a defined target for four-port testing. The 28-pin SOIC simplifies fixture-board assembly, but each downstream branch still requires its own protection and routing validation. Test software must be frozen before OTP programming to prevent production variation.

- Dedicated internal timing domains (vs Microcontroller without an integrated full-speed USB hub)
- Production-fixed programming model (vs Field-reprogrammable flash MCU architecture)
Design Notes
Keep USB differential pairs short, symmetric, continuously referenced, and away from switching-power loops. Place any required protection at the connector-facing side of the board, while placing the CY7C65113C-SXCT close enough to clock, decoupling, and relevant interface networks to minimize timing and return-path problems. The verified data does not include the complete pin table or recommended PCB stack-up, so board implementation must follow document 38-08002 Rev. *F rather than assumptions from generic USB layouts.
Design the 5 V rail and downstream-port power paths separately from the MCU’s local supply requirements. Verify the actual electrical-current limits, inrush behavior, voltage tolerance, and power-switch requirements against the complete manufacturer datasheet because these values are absent from the supplied excerpt. Include local high-frequency decoupling at the device supply pins and maintain low-impedance return paths under both idle and maximum downstream-port loading.
Do not treat the one-time-programmable 8 KB memory as reusable firmware storage. Finalize boot behavior, USB descriptors, port-control logic, and all board-specific constants before programming production units. Also verify the exact ordering code: CY7C65113C-SXC and CY7C65113C-SXCT appear as different supply forms in the verified listings, while CY7C63823-SXC is a different device and has not been established as pin compatible.
