supply voltage (3.3 V
±
10%); supplies internal digital
circuits
crystal oscillator output (12 MHz); connect a fundamental
parallel-resonant crystal; leave this pin open when using an
external clock source on pin XTAL1
crystal oscillator input (12 MHz); connect a fundamental
parallel-resonant crystal or an external clock source
(leaving pin XTAL2 unconnected)
digital ground
wake-up input (edge triggered); a LOW-to-HIGH transition
generates a remote wake-up from ‘suspend’ state
’suspend’ state indicator output (4 mA); used as a power
switch control output (active LOW) for powered-off
application or as a resume signal to the CPU (active HIGH)
for powered-on application
supply voltage (3.3 or 5.0 V)

Symbol names with an overscore (e.g. NAME) represent active LOW signals.
All outputs and I/O pins can source 4 mA of current.
7. Functional description
The ISP1581 is a high-speed USB device controller. It implements the USB 2.0/1.1
physical layer, the packet protocol layer and maintains up to 16 USB endpoints
concurrently (2 control, 14 configurable).
USB Chapter 9
protocol handling is
executed by means of external firmware.
