POWER SUPPLY CIRCUIT:
RESET CIRCUIT:
CLOCK CIRCUIT:
AVR-USB-162 can take power from two sources:
The board power consumption is: about 10÷15 mA with all peripherals and
MCU running at full speed, there are 5 different power saving(sleep) modes
which may put AT90USB162 in power down mode and in these modes the
consumption of the MCU is only few micro amperes.
AVR-USB-162 reset circuit is made-up with RC group R1 - 33K and C13 -
100nF (NA).
External reset can be generated by PC1 prototype pin. Manual reset is
possible by the RESET button.
Quartz crystal 8Mhz is connected to AT90USB162. Internal USB PLL
circuit can multiply this frequency up to 48MHz.
- USB connector where 5V power supply is applied by USB host
- Power Input (PWR) where 9VDC or 6VAC may be applied
