CY7C65630-56LFXC

The CY7C65630-56LFXC belongs to CY7C656xx family. The CY7C65630-56LFXC descriptor for CY7C656xx is based on the information found in the SPI EEPROM. The information in the EEPROM overrides the default descriptor values. If no EEPROM is used, the CY7C656xx enumerates with the default descriptor values as shown below. If a blank EEPROM is connected, the hub enumerates as vendor defined class instead of a hub class. This is for the purpose of programming the EEPROM with the cypress driver.

The features of CY7C656xx can be summarized as (1)USB 2.0 hub controller; (2)automotive AEC grade option (40 -85); (3)compliant with the USB 2.0 specification; (4)USB-IF Certified: TID# 30000009; (5)windows hardware quality lab (WHQL) - compliant; (6)up to four downstream ports supported; (7)supports bus powered and self powered modes; (8)single transaction translator (TT); (9)Bus power configurations; (10)fit/form/function compatible with CY7C65640 and CY7C65640A (TetraHub?); (11)space saving 56-pin QFN; (12)single power supply requirement:internal regulator for reduced cost; (13)integrated upstream pull up resistor; (14)integrated pull down resistors for all downstream ports; (15)integrated upstream and downstream termination resistors; (16)integrated port status indicator control; (17)24 MHz external crystal (integrated PLL); (18)in-system EEPROM programming; (19)configurable with external SPI EEPROM:vendor ID, product ID, device ID (VID/PID/DID); number of active ports; number of removable ports; maximum power setting for high-speed and full-speed; hub controller power setting; power on timer; overcurrent detection mode; enabled/disabled overcurrent timer; overcurrent pin polarity; indicator pin polarity; compound device; enable full-speed only; disable port indicators; ganged power switching; self and bus powered compatibility; fully configurable string descriptors for multiple ; (20)language support.
