MCHPUSB2513B-AEZC
Overview
The USB2513B-AEZC is a high-performance, low-power 3-port USB 2.0 Hi-Speed hub controller designed for embedded applications. It provides downstream port expansion with a small 36-QFN footprint, supporting multi-TT (Transaction Translator) for efficient data handling across various speeds. The controller is configurable via I2C, SMBus, or internal default settings to tailor the hub behavior to specific system requirements.
Why Choose This Part
This controller features MultiTRAK technology which utilizes a dedicated Transaction Translator per port to prevent bandwidth bottlenecks when mixing high-speed and full-speed devices. It offers significant power efficiency with a low 65mA base operating current and flexible configuration options through an external EEPROM or a system SMBus master. The 6x6mm QFN package is ideal for space-constrained PCB designs that require reliable USB 2.0 throughput.
Applications
Key Specifications
Getting Started
Designers can evaluate the chip using the EVB-USB2513B evaluation board to test port throughput and power consumption. Integration requires a 24MHz crystal and a 3.3V supply, with optional pull-up resistors on the SMBus lines for custom configuration. Microchip provides reference schematics and layout guidelines to ensure signal integrity for the 480Mbps differential pairs.
