note 1: for the at88sa100, at88sa102, and the at88sa10hs devices, 5.0v is required to burn the fuses. note 2: the at88microbase is shipped with a 16mhz crystal, which allows the at90usb1287 on-chip usart to obtain the 230.4k baud rate (-3.5% error) required to communicate with a cryptoauthentication device. the 16mhz crystal requires that 5 . 5 vcc 5 . 4 ? ? . to operate the at88microbase below 4.5v, the 16mhz crystal must be replaced with an 8mhz crystal. the abm3b-8.000mhz-b2-t 8mhz crystal is a drop-in replacement. 3.2.2 power led, ?ledp? the blue led (ledp) is always lit when power is applied to the at88microbase regardless of the voltage supply. figure 4. power on led ?ledp? 3.3 reset although the at90usb1287 has it s on-chip reset circuitry, (c .f. at90usb1287 datasheet, section ?system control and reset?), the at88microbase provides two additional means to reset the at90usb1287. 3.3.1 power-on reset the on-board rc network acts as power-on reset. 3.3.2 reset push button by pressing the reset push button on the at88 microbase, a warm r eset of the at90usb1287 avr is performed. figure 5. reset push button (avr reset) implementation
at88sck109stk3 3-8 at88ck109stk3 user guide 8699a?crypto?10/09 3.4 at90usb1287 avr microcontroller to use the usb interface of the at90usb1287, the clock source should always be a crystal or an external clock osc illator (the inte rnal 8mhz rc oscillator cannot be used to operate the usb interface). only the following crystal frequencies allow proper usb operations: 2mhz, 4mhz, 6mhz, 8mhz, 12mhz, and 16mhz. the at88mi crobase comes with a default 16mhz crystal oscillator, which is required to obtain the 230.4k usart baud rate needed for cryptoauthentication communication. 3.5 serial links 3.5.1 usb the at88microbase is supplied with a standard usb type-a receptacle. the at88microbase only operates as an ?usb device?. figure 6. usb type-a receptacle 3.5.2 usart the at90usb1287 avr comes with an on-chip usart peripheral (usart1). only the asynchronous mode is supported. see section 3.6.3 for pinout details. 3.5.3 spi / twi selector switch the spi ? twi selector switch (k1) allows either the spi pins (mosi and sclk) or the twi pins (sda and scl) to be routed to the 10 pin interf ace header, j1. see section 3.6.3 for pinout details. figure 7. twi ? spi selector switch
3.6 on-board resources 3.6.1 description of led bank the at88microbase includes 3 general purpose re d leds, which are connected to pd6, pd5 and pd4. to light an led, the corresponding port pin must be driven high. to turn off an led, the corresponding port pin must be driven low. figure 8. leds implementation schematic note : avr can source or sink enough current to drive an led directly. 3.6.2 buzzer the small onboard buzzer adds audio capability to the at88microbase board. the buzzer requires that pd7 be driven with a square wave at 4.0 0.5 ? khz to achieve a maximum decibel of 78db. spi twi spi twi k1 twi position k1 spi position

at88sck109stk3 3-12 at88ck109stk3 user guide 8699a?crypto?10/09 the following sections 3.7 ? 3.11 describe the at88ck109bk3 cryptoauthentication daughter board. 3.7 at88ck109bk3 cryptoauthentication daughter board figure 13. at88ck109bk3 components (top side) at88ck109bk3 has two sot23-3 sockets that support the at88sa100, at88sa102, and the at88sa10hs 3-leads devices. figure 14. chip-in-socket placement (live bug) 3.8 at88ck109bk3 host and client sockets compatibility at88ck109bk3 is supplied with two sot23-3 sockets titled host and client. since both sockets have identical pinout?s, the at88microbase can physically accept a host or a client device in either socket. therefore, the at88ck109bk3 can be configured for either a host-client or client- client development. sot23-3 socket interconnect header host pwr led client pwr led 10-pin interface header
note: when using the demonstration software, the host (at88sa10hs) and client (at88sa100 or at88sa102) devices must be in their respective sockets according to th e ?host? and ?client? texts on the board. 3.9 host and client power configuration the at88ck109bk3 provides the user with the capability to independently power cycle each socket with software or place the sockets in a constant power-on state, assuming power is applied to the board. figure 15. host and client power headers figure 16. schematic implementation for software power control, host-side table 1. host and client sockets power configuration jumpers position comments view hardware power configuration h1, h2, h3 and h4 mounted with all 4 jumpers mounted, the host and client sockets are placed into a constant power?on state. *default setting h2 h1 h4 h3

at88sck109stk3 3-16 at88ck109stk3 user guide 8699a?crypto?10/09 3.12 interfacing a usart with cryptoauthentication a microcontroller?s usart require s a minimum of two signals (rxd and txd) to communicate. the at88sa100, at88sa102, and at88sa10hs device s have a 1-wire communication interface. the make the usart compatible with a 1-wire cr yptoauthentication device, the usart?s pins (tx and rx) are tied together. figure 19. usart txd and rxd pins configured for 1-wire interfacing on the at88ck109bk3, px2 and px3 are tied togeth er with a zero ohm resistor (r11). when mounted to the at88microbase, pins px2 and px3 align with pins (pb3/pd2) and (pb7/pd3). the usart pins, pd2 (rxd) and pd3 (t xd), are effectively tied together with r11allowing the usart to be compatible with the cryptoauthentication 1-wire interface. 3.13 in-system programming 3.13.1 programming with usb bootloader: dfu (device firmware upgrade) at90usb1287 avr comes with a default factory pre-programmed usb bootloader located in the on-chip boot section of the at90usb1287. this is the easiest and fastest way to reprogram the device directly over the usb interface. the ?flip? pc side application, available for free on atmel website, offers a flexible and user friendly inte rface for reprogramming the application over the usb bus. the ?hwb? push button is used to place t he avr into dfu mode after reset (refer to at90usb1287 datasheet section ?boot loader support?). the following steps enable the dfu mode: 1. press and hold ?hwb? button 2. press the ?reset? button 3. release the ?resett? button. 4. release the ?hwb? button. for more information about the usb bootloader and flip software, please refer to the ?usb bootloader datasheet? document and ?flip user manual?. note: hwbe fuse must be enabled to support dfu.
3.13.2 programming with avr jtag ice the at90usb1287 can be programmed using specific the jtag link. this sub-section will explain how to connect and use the avr jtag ice. note: when the jtagen fuse is disabled, the fo ur tap pins are normal port pins, and the tap controller is in reset. when the jtagen fuse is enabled, the input tap signals are internally pulled high. this enables the jtag for boundary-scan and programming. the at90usb1287 device is shipped with this fuse programmed. figure 20. connecting avr jtagice mkii to the at88microbase the flash, eeprom and all fuse and lock bit op tions isp-programmable, can be programmed individually or with the sequenti al automatic programming option. note: see avr studio? on-line help for information. 3.14 debugging 3.14.1 debugging with avr jtag ice mkii every at88ck109stk3 can be used for debugging with jtag ice mk ii. connect the jtag ice mkii as shown in figure 20, for debugging help; please refer to avr studio? help information.
at88sck109stk3 3-18 at88ck109stk3 user guide 8699a?crypto?10/09 when using jtag ice mk ii for debugging, and as at90usb1287 parts are factory configured with the higher security level set, a chip eras e operation will be performed on the part before debugging. thus the on-chip flash bootloader w ill be erased. it can be restored after the debug session using the bootloader hex file available from atmel website. 3.15 test points there are 4 test points implemented, these test points are referenced in the full schematics section. ? vcc, at88ck109bk3 ? gnd at88ck109bk3 ? host signal pin at88ck109bk3 interconnect header ? client signal pin at88ck109bk3 interconnect header
