Microchip Launches Highperformance USB2514B Controller

In today's rapidly evolving technological landscape, the demand for high-performance, low-power, and highly integrated USB solutions continues to grow. Microchip Technology addresses this need with its flagship USB 2.0 hub controller series—the USB2514B—delivering exceptional performance, flexible configuration, and innovative technology to power next-generation designs.

Setting New Benchmarks in Efficient Connectivity

The USB2514B series features a compact 36-pin QFN (6x6mm) package that integrates robust functionality within minimal space. Fully compliant with USB 2.0 specifications, the controller leverages Microchip's proprietary MultiTRAK™ technology to achieve industry-leading Transaction Translator performance. This architecture ensures each downstream port operates independently for optimal data throughput, eliminating performance bottlenecks even in mixed-speed environments.

Intelligent Design for Maximum Flexibility

Recognizing the importance of design flexibility and cost-efficiency, the USB2514B series incorporates over 30 programmable configuration options. Innovative features like PortMap™, PortSwap™, and PHYBoost™ provide system designers with unprecedented control:

• PortMap™ enables flexible port mapping and disable sequencing
• PortSwap™ simplifies PCB layout through programmable USB differential pair pin locations
• PHYBoost™ offers four adjustable USB signal drive strength levels to maintain signal integrity

Energy-Efficient Operation for Sustainable Solutions

While delivering high performance, the USB2514B series prioritizes power efficiency through granular power management. The controller supports independent or grouped control of downstream ports to minimize energy consumption. An integrated 1.2V core voltage regulator works with an external 3.3V single power supply to simplify power design and improve overall efficiency. The integration of USB termination and pull-up/down resistors further reduces external component requirements and BOM costs.

Versatile Applications Across Industries

The USB2514B series serves diverse high-growth markets with its combination of performance and flexibility:

• Mobile PC expansion: Additional USB ports for laptops
• Smart displays and televisions: Enhanced connectivity for entertainment systems
• PC motherboard integration: Optimized USB expansion for desktop systems
• Gaming consoles: Multi-peripheral support for gaming applications
• Multifunction printers: Improved connectivity options
• Networking equipment: Reliable USB connections for modems and set-top boxes
• Storage devices: High-speed data transfer for HDD/SSD enclosures
• Industrial applications: Robust connectivity for automation and embedded systems

Future-Ready Charging Capabilities

The series supports USB Battery Charging Specification Rev. 1.1, with configurable downstream ports that can operate as Charging Downstream Ports (CDP). This enables compliant products to provide universal battery charging functionality for mobile phones and portable electronics.

Reliable Performance for Demanding Environments

The USB2514B series offers two temperature range options to accommodate different operating conditions. The USB251xB variant supports extended commercial temperature ranges (0°C to +85°C), while the USB251xBi series is designed for industrial environments (-40°C to +85°C). All devices feature 4kV HBM ESD protection (JESD22-A114F) to ensure reliability during powered and unpowered operation.

Comprehensive Design Support

Microchip Technology complements its hardware offerings with extensive design resources, including documentation, evaluation boards, and configuration tools.
