Hi-Speed USB peripheral controller

Table 2: Pin description…continued

Symbol[1] Pin

Type[2] Description

WAKEUP 55

I

wake-up input; when this pin is at the HIGH level, the chip is

prevented from getting into the suspend state and the chip

wakes up from the suspend state; when not in use, connect

this pin to ground through a 10 kΩ resistor

input pad; TTL; 5 V tolerant

SUSPEND 56

O

suspend state indicator output; used as a power switch

control output for powered-off application or as a resume

signal to the CPU for powered-on application

CMOS output; 8 mA drive

GND

exposed -

die pad

ground supply; down bonded to the exposed die pad

(heatsink); to be connected to DGND during PCB layout

[1] Symbol names ending with underscore N (for example, NAME_N) represent active LOW signals.

[2] All outputs and I/O pins can source 4 mA.

[3] Add a decoupling capacitor (0.1 µF) to all the supply pins. For better EMI results, add a 0.01 µF

capacitor in parallel to the 0.1 µF.
