AT43DK355 usb controller dev. kit user guide 3-1 3429c?usb?7/04 section 3 hardware description the following hardware description explains the development board in detail. the development board schematic can be found in section 6.2. figure 3-1. simple block diagram of the dk355 board 3.1 leds (ld0 to ld7) the AT43DK355 development kit includes 8 green leds. the anode pin of each led is connected to the vbus, through a resistor. 3.2 5x2 header jp14 each pin of this header is connected to the cathode pin of each led. to turn on the led, jp14 is pulled low. 3.3 8 dip switch sw1 positioning a switch to on causes the corresponding swx pin on jp16 to be pulled low while releasing it will result in a high im pedance state.
hardware description 3-2 AT43DK355 usb controller dev. kit user guide 3429c?usb?7/04 3.4 5x2 header jp16 these headers are connected to one of each dip switch. 3.5 db 25 female parallel port connector j4 the parallel port connector, j4, is used for in-system programming to upload firmware from the pc to the seeprom u4. a db25 ma le-to-male parallel cable is supplied to connect the j4 connector to the pc paral lel port. further description on downloading code to the seeprom is available in section 3 of the usb wizard: application exam- ples and demos document for the at43usb355. 3.6 8-pin ic socket u4 the seeprom device is plugged to this 8-pin socket to store programming memory. this board is supplied with an atmel 25hp256 seeprom. 3.7 variable resistor r15 variable resistor r15 can be used to adjust voltage of the vref pin of the at43usb355 in order to test the analog to digital converter (adc) feature. this resistor produces variable voltage levels that can be fed to the adc input header (jp6 and jp5). the volt- age produced from this resistor can be accessed from pin 4 of header jp9. 3.8 2x2 header jp9 to use the adc, a reference voltage must be applied to the vref pin of the at43usb355. this reference voltage can be fixed at the cext voltage by setting a jumper between pin 1 and pin 2, or the re ference voltage can be adjustable (by adjusting r15) by setting a jumper between pin 3 and pin 4 of j9. jp9: 1-2 vref = cexta (jumper installed by default) 3-4 vref is adjustable 3.9 programmable logic device u2 this development board uses the atf16v8c z electrical erasable pld for in-system programming and for downloading data from seeprom to at43usb355. 3.10 5x2 header jp5 and 2x2 header jp6 jp5 are input pins for adc channels zero to seven and jp6 are for adc channels eight to eleven. 3.11 4x2 header general purpose i/o port a/jp1 accessing porta externally can be perform ed at this header. a number is assigned to each pin header, ?0? to ?7?, corresponds to the port's pin number. 3.12 4x2 header general purpose i/o port b/jp2 accessing portb externally can be perform ed at this header. a number is assigned to each pin header, ?0? to ?7?, corresponds to the port's pin number.
hardware description AT43DK355 usb controller dev. kit user guide 3-3 3429c?usb?7/04 3.13 4x2 header general purpose i/o port d/jp4 accessing portd externally can be performed at this header. a number is assigned to each pin header, ?0? to ?7?, corresponds to the port's pin number. 3.14 2x2 header general purpose i/o jp3 external access to pf0 to pf3 is available at this header. these pins are used to down- load programing from the seeprom to the at 43usb355e as soon as power is applied to the board. once firmware is downloade d, the at43usb355 drives pf0 high while leaving pf1-pf3 as a general purpose i/o. pf3 also has an alternate function as the icp input capture pin for the timer/counter1. 3.15 2x2 header jp8. this header will take effect whenever the pulse width modulation (pwm) feature is enabled. the 43usb355e has two pwm features, pwm1 and pwm2, which are output- ting to pd5 (port d pin 5) and pd6 (port d pin 6). installing jumpers to these pins, connect pwm outputs to the base of transistors, q2 and q4 to amplify pwm signals. if the pwm feature is disabled, pd5 and pd6 w ill be available as gen eral purpose i/os. jp8: 1-2 pd5 = pwm1 (jumper installed by default) 3-4 pd6 = pwm2 (jumper installed by default) 3.16 2x2 header jp13 there are three pins marked as pwm1, pwm2 and vbus at this header. the pwm1 and pwm2 pins can be used to drive dc motors. the pin marked vbus is the 5v usb upstream port voltage. 3.17 2x2 header jp11 this development board provides a ganged power switching and overcurrent sensing features for two downstream usb ports. this feature occupies pd0 and pd1 and requires the use of the micrel mic2026-2bm solid state power switch. the pd0 and pd1 must be connected to this power switch by installing a jumper to this header. if this system is not used, pd0 and pd1 will be available as general purpose i/os. jp11: 1-2 pd1 = downstream usb power switching enable (jumper installed by default) 3-4 pd0 = overcurrent protection enable (jumper installed by default) 3.18 solid state power switch u3 this device manages the ganged power switching system and overcurrent sensing fea- ture. this board uses the micrel mic2026-2bm. 3.19 2x2 header jp12 the pin marked as vbus provides usb downstream port voltage. if the application requires the use of the micrel mic2020-2bm for power switching and overcurrent pro- tection, no jumpers are installed on jp12; otherwise, a jumper is needed between pin 1 and pin 2 of jp12. jp12: 1-2 connected = no power switching unconnected = power switching (default) 3-4 no connection
hardware description 3-4 AT43DK355 usb controller dev. kit user guide 3429c?usb?7/04 3.20 header gnd tp1 and tp2 this pin provides ground voltage reference. 3.21 header jh1 v icp input capture pin for the timer/counter1 feature. 3.22 usb external downstream port j2 and j3 connectors these connectors provide downstream connection to usb devices. there are 3 down- stream ports. port 1 is permanently used by embedded functions and is not visible. on this board, be aware that j3 corresponds to usb port 2 of 43usb355e and j2 corre- sponds to usb port 3 of 43usb355e. the power source of these ports is controlled by power switch u3. 3.23 usb upstream port j1 connector this connector provides upstream connection to a host or to another hub. 3.24 programmable microcontroller u1 this board comes with the at43usb355e microcontroller.
