Product Overview

The USB2640-HZH-02 is an USB 2.0 compliant hi-speed Hub for USB port expansion with an attached mass storage class peripheral controller. The controller allows read/write capability to popular flash media from the following families: Secure Digital (SD), MultiMediaCard (MMC), xD-Picture Card (xD) and Memory Stick® (MS). It is a fully integrated, single chip solution providing USB expansion and integrated flash card media reader/writer capability of ultra-high performance operation. Average sustained transfer rates exceeding 35MB/s are possible. The hub controller with internally connected ultra-fast flash media reader/writer and 2 exposed downstream ports for external peripheral expansion. It features the flexible port mapping and port disable sequencing supports multiple platform designs, programmable USB differential-pair pin locations eases PCB design by aligning USB signal traces directly to connectors and programmable USB transceiver drive strength recovers signal integrity.
  • Transaction translator in the hub supports operation of full-speed and low-speed peripherals
  • Enhanced EMI rejection and ESD protection performance
  • On-board 24MHz crystal driver circuit
  • Optional external 24MHz clock input
  • Up to 9 GPIOs for special functions
  • 8051 8-bit Microprocessor
  • EEPROM update via USB
