Description
Negative power supply, ground
Bidirectional I/O lines. Software instructions determine the CMOS out-
put or Schmitt trigger input with pull-high resistor (determined by
pull-high options).
PC0 can be used as USB mouse IRPT control pin for mouse hardware
wake-up function
Schmitt trigger reset input. Active low
Positive power supply
3.3V regulator output
USBD+ or PS2 CLK I/O line
USB OR PS2 function is controlled by software control register
USBD- or PS2 DATA I/O line
USB or PS2 function is controlled by software control register
OSC1, OSC2 are connected to an 6MHz or 12MHz Crystal/resonator
(determined by software instructions) for the internal system clock.
Absolute Maximum Ratings
Supply Voltage ...........................VSS-0.3V to VSS+6.0V
Input Voltage..............................VSS-0.3V to VDD+0.3V
Storage Temperature ............................-50°C to 125°C
Operating Temperature...............................0°C to 70°C
Note: These are stress ratings only. Stresses exceeding the range specified under ²Absolute Maximum Ratings² may
cause substantial damage to the device. Functional operation of this device at other conditions beyond those
listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliabil-
ity.
