Frequently Asked Questions
How many USB ports does USB5926-I/KD support, and what is the maximum data transfer rate per port?
USB5926-I/KD is a 7-port USB 3.1 Gen 1 hub controller supporting SuperSpeed data transfer rates up to 5 Gbps per port, with a total system throughput of up to 625 MBps. This makes it suitable for high-bandwidth peripherals such as SSDs, cameras, and multi-gigabit USB network adapters in docking station designs.
How can the USB5926-I/KD be configured after assembly, and which interfaces are supported for runtime control?
USB5926-I/KD supports post-assembly configuration via I2C, SPI, SMBUS, and UART interfaces running at up to 25 MHz. This allows embedded firmware to customize port enabling, power management, and device descriptors without requiring a hardware redesign, which is valuable for industrial platforms serving multiple product variants.
What package does USB5926-I/KD use, and what PCB design considerations apply for the 100-pin VQFN?
USB5926-I/KD is supplied in a 100-pin VQFN (PQCC-N100) package with a 0.47 mm body and square profile, requiring fine-pitch SMT assembly. Designers should plan a thermal pad under the IC for heat dissipation and use a via array in the exposed pad area to manage thermal resistance on high-density PCBs.
What is the lifecycle status of USB5926-I/KD, and are there supply risks for long-term industrial projects?
USB5926-I/KD was introduced in October 2016 and currently shows a YTEOL of 0, which indicates it may be approaching end-of-life or transitioning to a newer revision. Procurement and engineering teams designing long-term industrial or embedded systems should confirm the current lifecycle status with Microchip and evaluate migration to a successor part if necessary.
