This signal provides power to the chip. 7 VCC Power N/A VCC. This signal provides power to the chip. 11 VCC Power N/A VCC. This signal provides power to the chip. 15 VCC Power N/A VCC. This signal provides power to the chip. 19 VCC Power N/A VCC. This signal provides power to the chip. 23 VCC Power N/A VCC. This signal provides power to the chip. 27 VCC Power N/A VCC. This signal provides power to the chip. 33 VCC Power N/A VCC. This signal provides power to the chip. 39 VCC Power N/A VCC. This signal provides power to the chip. 45 VCC Power N/A VCC. This signal provides power to the chip. 55 VCC Power N/A VCC. This signal provides power to the chip. 4GND Power N/A GND. Connect to Ground with as short a path as possible. 8GND Power N/A GND. Connect to Ground with as short a path as possible. 12 GND Power N/A GND. Connect to Ground with as short a path as possible. 16 GND Power N/A GND. Connect to Ground with as short a path as possible. 20 GND Power N/A GND. Connect to Ground with as short a path as possible. 24 GND Power N/A GND. Connect to Ground with as short a path as possible. 28 GND Power N/A GND. Connect to Ground with as short a path as possible. 34 GND Power N/A GND. Connect to Ground with as short a path as possible. 40 GND Power N/A GND. Connect to Ground with as short a path as possible. 47 GND Power N/A GND. Connect to Ground with as short a path as possible. 50 GND Power N/A GND. Connect to Ground with as short a path as possible. 56 GND Power N/A GND. Connect to Ground with as short a path as possible. 21 XIN Input N/A 24-MHz Crystal IN or External Clock Input. 22 XOUT Output N/A 24-MHz Crystal OUT. 46 RESET# Input N/A Active LOW Reset. This pin resets the entire chip. It is normally tied to VCC through a 100K resistor, and to GND through a 0.1-µF capacitor. Other than this, no other special power-up procedure is required. 26 BUSPOWER Input N/A VBUS. Connect to the VBUS pin of the upstream connector. This signal indicates to the hub that it is in a powered state, and may enable the D+ pull-up resistor to indicate a connection. (The hub will do so after the external EEPROM is read, unless it is put into a high speedhigh speedhigh speed mode by the upstream hub). The hub can not be bus powered, and the VBUS signal must not be used as a power source. SPI INTERFACE 25 SPI_CS O O SPI Chip Select. Connect to CS pin of the EEPROM. 48 SPI_SCK O O SPI Clock. Connect to EEPROM SCK pin. 49 SPI_SD I/O/Z Z SPI Dataline Connect to GND with 15-K Ω resistor and to the Data I/O pins of the EEPROM. UPSTREAM PORT 17 D– I/O/Z Z Upstream D– Signal. 18 D+ I/O/Z Z Upstream D+ Signal. [+] Feedback |
