INFO:
AT90USB162
is the easiest way to add USB functionality to your next device, Atmel
provide free open source HID (mouse, keyboard) and CDC (USB-to-RS232) code
and on top of this AT90USB162 cost is same as ATMega16, so what you are
waitng for? AVR-USB-162 board provide the basic circuit necessary to work
with AT90USB162 - USB connector and circuit, external power supply if your
circuit require more power than 100mA which usually USB port provide, button,
status LED, reset button. All AT90USB162 come from Atmel pre-programmed
with bootloader which allow code to be programmed inside the chip without
any external programmer, just download the FLIP software from Atmel web
site and load your HEX code inside AT90USB162. To enter the bootloader
mode you shoud press and hold BUT button, then press and release RST button.
If you preffer to use ICSP programmer note that only AVR-ISP-MK2 is supporting
AT90USB162 as there are pretty new devices, probably AVR Dude will add
support later, but for the moment you can't use AVR-PG1 or AVR-PG2 for
ICSP programming, another bad news is that AT90USB162 supports only debug
Wire not JTAG so to debug it you should have the expensive AT-JTAGICE-MK2.
FEATURES:
AT90USB162
microcontroller with 16KB Flash, 512B RAM, 512B EEPROM
ICSP
5x2 pin connector for in-circuit programming with AVR-ISP-MK2 (you generally
don't need to use ICSP as you can program via USB)
Debug
Wire could be performed by 3 wires connected to ICSP (AT-JTAGICE-MK2 have
such lose wire connector which to be used, you need VCC, GND, RST signals
only)
USB
2.0 Full speed connector
user
button BUT (can be used to enter bootloader mode after reset)
reset
button RST
takes
power from USB no need for external adapter
external
power supply and voltage regulator if USB can't provide enough power
Quartz
crystall oscilator circuit 8Mhz
