INTRODUCTION AVR-H128-CAN is inexpensive way to develop and prototype circuits with AT90CAN128 without need to deal with SMD soldering. All microcontroller pins are available on extension header with 0.1" and power supply, oscillators, ICSP, JTAG are wired, so all you need to do is to connect your additional components to the AVR ports, as the step is 0.1" these headers perfectly fit the prototype sea of pad boards with 0.1" step. BOARD FEATURES – AT90CAN128-16AU microcontroller with 128KB Flash, 4KB RAM, 4KB EEPROM, CAN controller – ICSP 5x2 pin connector for in-circuit programming with AVR-PG1 or AVR-PG2 or STK500 compatible programmer – JTAG 5x2 pin connector for in-circuit debugging with AVR-JTAG-L or AVR- JTAG-USB – 16MHz scillator circuit – 32768 Hz oscillator circuit – Reset IC ZM33064 – +5V voltage regulator LM78L05 – power supply filtering capacitors – extension pin headers for each uC pin – FR-4, 1.5 mm (0,062"), green soldermask, white silkscreen component print – dimensions 47x47 mm (1.85x1.85") ELECTROSTATIC WARNING The AVR-H128-CAN board is shipped in protective anti-static packaging. The board must not be subject to high electrostatic potentials. General practice for working with static sensitive devices should be applied when working with this board. BOARD USE REQUIREMENTS Cables: The cable you will need depends on the programmer/debugger you use. If you use AVR-JTAG or AVR-PG1 you will need RS232, if you use AVR-USB-JTAG or AVR-ISP500/TINY/ISO you will need 1.8 m A-B USB cable, if you use AVR- PG2, you will need LPT cable. Hardware: One of OLIMEX Programmers/Debuggers – AVR-JTAG, AVR-USB- JTAG, AVR-ISP500, AVR-ISP500-TINY, AVR-ISP500-ISO, AVR-PG1, AVR-PG2. Software: AVR C compiler. Page2
