Type
EEPROM – Chip Select. Tri-State during device reset.
Clock signal to EEPROM. Tri-State during device reset. When not in reset, this
outputs the EEPROM clock.
EEPROM – Data I/O Connect directly to Data-In of the EEPROM and to Data-Out
of the EEPROM via a 2.2K resistor. Also, pull Data-Out of the EEPROM to VCC via
a 10K resistor for correct operation. Tri-State during device reset.
Oscillator input.
Oscillator output.
Current reference – connect via a 12K Ohm resistor @ 1% to GND.
USB Data Signal Minus.
USB Data Signal Plus.
IC test pin – for normal operation should be connected to GND.
Reset input (active low).
Active low power-enable output.
PWREN# = 0: Normal operation.
PWREN# =1 : USB SUSPEND mode or device has not been configured.
This can be used by external circuitry to power down logic when device
is in USB suspend or has not been configured.
Active low when USB is in suspend mode.
