Bus type: M.2 A+E Key. Supports 4/3/2 downstream ports through I/O pin configuration. Upstream port supports high-speed () and full-speed () traffic Downstream port supports , and low-speed () traffic. 1 control pipe (endpoint 0, 64-byte data payload) and 1 interrupt pipe (endpoint 1, 1-byte data payload) On-chip 8-bit microprocessor. RISC-like architecture USB optimized instruction set Performance: 6 MIPS@12MHz With 64-byte RAM and 2K Mask ROM Supports customized PID, VID by reading external EEPROM Supports downstream port configuration by reading external EEPROM Low power consumption, built-in 5V to 3.3V regulator Integrated USB 2.0 transceiver Each downstream port supports two-color status indicator with automatic and manual modes compliant with USB specification revision 2.0 Built-in upstream 1.5K pull-up and downstream 15K pull-down Embedded serial resistor for USB signals Supports individual and joint modes for power management and over-current detection for downstream ports Power enable pin supports low/high enable power switch Compliant with bus power requirements Automatically switches between self-powered and bus-powered modes Supports composite devices through I/O pin configuration (downstream ports are not removable) Built-in PLL supports external 12MHz crystal/oscillator clock input Improved output driver with slew rate control to reduce Internal power failure detection for ESD recovery Number of downstream ports can be configured through GPIO without external EEPROM Color: As Shown Material: plastic Package Contents: 1 * Motherboard hub industrial control conversion card Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
