ATADAPCAN01 Microchip

ATADAPCAN01 - STK501 CAN Extension The ATADAPCAN01 - STK501 CAN add-on is an extension to the STK500 and CAN STK501 development boards from Atmel Corporation, adding support for the AVR AT90CAN128 device in a single development environment. Microcontrollers The AVR AT90CAN128 includes a built-in Controller Area Network (CAN) controller with all the features required to implement the CAN serial communication protocol in accordance with the BOSCH GmbH CAN specification. Quick Start The add-on board provides CAN transceivers, termination options and other features necessary to seamlessly connect the STK500 development environment to a CAN Guide bus for application development and debugging. Requirements STK500 starter kit, serial cable and power supply STK501 topmodule to STK500 AVR AT90CAN128 in 64-pin TQFP package Rev. 4330B-CAN03/04 1 Connections to The ATADAPCAN01 module is intended for use with the STK500 and STK501 starter kits. The STK501 holds the 64-pin TQFP ZIF socket for the AT90CAN128 part, and is a STK500 / STK501 top-module board for the AVR starter-kit STK500. The ATADAPCAN01 requires con- nections to the CANTx and CANRx signals on the AVR device, as well as Vcc and GND connections. The ATADAPCAN01 board can be connected to the starter-kits in one of three possible ways: Individual signal wiring to PORTD. Using three 2-wire cables provided with the STK500 kit, make the following connections: STK500 PD5 (pin6) to ATADAPCAN01 PORTD pin 6 (CANTx) STK500 PD6 (pin7) to ATADAPCAN01 PORTD pin 7 (CANRx) STK500 GND & VTG to ATADAPCAN01 PORTD pins 9 & 10 Flat-cable connection to PORTD. Using a 10-wire flat-cable provided with the STK500 kit, connect the PORTD header of the STK500 to the PORTD header of the ATADAPCAN01, as shown in figure 1. Care should be taken to use the correct pin orientation. Figure 1. Connecting to the STK500 through a 10-wire flat-cable ATADAPCAN01 STK-500 Direct mounting onto PORTD. A second PORTD header is routed (but not mounted) on the ATADAPCAN01 (J8). By attaching a matching 10 pin socket to the underside of the board, it can be mounted directly onto the STK500 PORTD header. The top-side PORTD header on the ATADAPCAN01 board can then be used to access other PORTD pins. 2 AT90CAN128 4330BCAN03/04
