Overview ATAVRAUTO100 User Guide Congratulations on your selection of the ATAVRAUTO100. This board includes all ele- ments necessary for designers to quickly develop code related to CAN and LIN communication gateway implementing the AT90CAN128 and for prototyping and testing of new designs. - Page 4 – for on-chip debugging using JTAG ICE Serial interfaces: – 1 CAN interface (High Speed and Low Speed) – 1 LIN interface 1.3 and 2.0 compliant (Software library available on the Atmel website for LIN 1.3). On-board resources: – 1 high speed CAN transceiver ATA6660 –...

Using calibration methods as described in application notes avail- able at www.atmel.com/avr it is possible to achieve ± 2% accuracy at any given VCC and temperature. When this Oscillator is used as the chip clock, the Watchdog Oscillator will still be used for the Watchdog Timer and for the Reset Time-out. -

Necessary for the CAN network precision, the following crystal frequency allows proper ATAVRAUTO100 operations : 8MHz, 12MHz, 16MHz. The ATAVRAUTO100 comes with a default 8MHz crystal oscillator (CAN baut rate up to 1MBit/sec). The LIN master mode clock should always be a crystal or external clock oscillator. Cur- rently, only 8MHz and 16MHz crystal oscillator is supported. - Page 8 CAN+ are connected. The signals are routed to ATA6660 CAN high speed transceiver. Figure 2-5. CAN High Speed connections The blue LED is illuminated when the ATAVRAUTO100 is correctly powered, i.e. volt- age higher than +5V is present on the LIN connector.

. It i s po we r ed by th e ATAVRAUTO100 and an additional power supply is thus not required. The AVR ISP programming interface is integrated in AVR Studio®. - Page 10 For AT90CAN128 these pins are mapped to PDI (PE0) and PDO (PE1). To program the device using AVR ISP programmer, connect the AVR ISP to the adaptor (ATAVRAUTO900) and connect the adaptor to the connector of the ATAVRAUTO100. ATAVRAUTO100 User Guide...
- Page 11 The AT90CAN128can be preogrammed using specific JTAG link: 3-wire debug-wire interface. To use the AVR JTAGICE mkII with an ATAVRAUTO100 an optional adaptor should be used. Then the JTAG probe can be connected to the ATAVRAUTO100 as shown in the following figure.
