Description
EEPROM – Chip Select. For 48MHz operation pull EECS to GND using a 10k
resistor. For 6MHz operation no resistor is required. Tri-State during device reset.
Clock signal to EEPROM. Tri-State during device reset, else drives out.
EEPROM – Data I/O Connect directly to Data-In of the EEPROM and to Data-
Out of the EEPROM via a 2k2 resistor. Also pull Data-Out of the EEPROM to
VCC via a 10k resistor for correct operation. Tri-State during device reset.

Description
Goes Low during USB Suspend Mode. Typically used to power-down an external
TTL to RS232 level converter i.c. in USB -> RS232 converter designs.
Goes Low after the device is configured via USB, then high during USB suspend.
Can be used to control power to external logic using a P-Channel Logic Level
MOSFET switch. Enable the Interface Pull-Down Option in EEPROM when using
the PWREN# pin in this way.
Bus Powered – Tie Low / Self Powered – Tie High
