TUSB2136 (ACTIVE)

Full-Speed 12Mbps USB 2 port Hub With General-Purpose 8052 MCU

 

Description

The TUSB2136 is an integrated universal serial bus (USB) hub with a general-purpose 8052 microcontroller that can be used for various USB controller applications. The TUSB2136 has 8K × 8 RAM space for application development. Using a 12-MHz crystal, the onboard oscillator generates the internal system clocks. No additional programming is required for any part of the hub functions. The device is programmed via an inter-IC (I2C) serial interface at power on from an EEPROM, or optionally, the application firmware can be downloaded from a host PC via USB. The 8052-based microprocessor allows several third-party standard tools to be used for application development. In addition, the application code available in the general market can also be used (this may or may not require some code modification due to hardware variations).

Features

    • 256 × 8 RAM for internal data
    • 8K × 8 RAM code space available for downloadable firmware from host or I2C port.
    • 512 × 8 shared RAM used for data buffers and endpoint descriptor blocks (EDB) [1]
    • Four 8052 GPIO ports (port 0, 1, 2 and 3)
    • Master I2C controller for external slave device access
    • Watchdog timer
  • Operates from a 12-MHz crystal
  • On-chip PLL generates 48 MHz
