SPIDI I V

max = 0.2V at I = 2mA

min = 2.55V at I = -0.5mA

max = 3.05V

max = 0.8V

min = 2.15V,

max = VEXTmin + 0.3V = 3.05V

If the Serial Peripheral Interface is

active the I

C interface is not avail-

able.

If lines are unused keep pins open.

USB VUSB_IN I V

min = 4.0V

max = 5.25V

All electrical characteristics

according to USB Implementers’

Forum, USB 2.0 Full Speed Spec-

ification.

Without Java: USB port

Under Java: Debug interface for

development purposes.

If lines are unused keep pins open.

GPIO1 I/O V

max = 0.2V at I = 2mA

min = 2.55V at I = -0.5mA

max = 3.05V

max = 0.8V

min = 2.15V,

max = VEXTmin + 0.3V = 3.05V

All pins which are configured as

input must be connected to a pull-

up or pull-down resistor.

If lines are unused (not config-

ured) keep pins open.

Alternatively, the GPIO10 pin can

be configured as a pulse counter

for pulse rates from 0 to 1000

pulses per second.
