3.3 RESET
Although the AT90USB1287 has its 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 AT88Microbase, a warm RESET of the AT90USB1287 AVR is performed.
Figure 5. RESET Push Button (AVR RESET) Implementation
AT88SCK109STK3
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 oscillator (the internal 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 AT88Microbase 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 Interface header, J1. See section 3.6.3 for pinout details.

3.6.1 Description of LED Bank
The AT88Microbase includes 3 general purpose red 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.

3.6.4 CryptoCompanion Chip
The AT88Microbase has one CryptoCompanion device (AT88SC108), which is located on the back side of board. The AT88SC018 is designed as the mate to Atmel’s CryptoRF® (CRF) and CryptoMemory® (CM) chips. The SCL and SDA pins are connected to PD0 and PD1, respectively. The RST and PDN pins are connected to PF2 and PF3, respectively.

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 client­client development.
3-12 AT88CK109STK3 User Guide
8699A—CRYPTO—10/09
Note: When using the demonstration software, the host (AT88SA10HS) and client (AT88SA100 or AT88SA102) devices must be in their respective sockets according to the “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.

3.12 Interfacing a USART with CryptoAuthentication
A microcontroller’s USART requires a minimum of two signals (RXD and TXD) to communicate. The AT88SA100, AT88SA102, and AT88SA10HS devices have a 1-wire communication interface. The make the USART compatible with a 1-wire CryptoAuthentication 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 together 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 (TXD), 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 interface for reprogramming the application over the USB bus.
The “HWB” push button is used to place the 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.
3-16 AT88CK109STK3 User Guide
8699A—CRYPTO—10/09
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 four 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 options ISP-programmable, can be programmed individually or with the sequential 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
When using JTAG ICE MK II for debugging, and as AT90USB1287 parts are factory configured with the higher security level set, a chip erase operation will be performed on the part before debugging. Thus the on-chip flash bootloader will 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.
