AVR-P40-8535 development board Users Manual All boards produced by Olimex are ROHS compliant Revision A, October 2009 Copyright(c) 2009, OLIMEX Ltd, All rights reserved Page1INTRODUCTION The AVR Microcontroller are low-power CMOS 8-bit controller based on the RISC architecture. The AVR core combines a rich instruction set with general purpose working registers. All the registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in one single instruction executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers. The AVR-P40-8535 is prototype board for 40 pin AVR microcontrollers with STKxxx compatible 10 pin ICSP connector. BOARD FEATURES STK200 compatible ICSP 5x2 pin connector for in-circuit programming with AVR-PG1 or AVR-PG2 JTAG 5x2 pin connectr for in-circuit programming and debugging with AVR-JTAG-USB and AVR-JTAG-L RS232 Tx, Rx interface with MAX232 IC on socket 8 MHz crystal on socket (user can replace with any value) reset IC ZM33064 reset button general purpose push button status LED connected to PB0 via removable jumper DIL40 microcontroller socket Power plug-in jack selectable +3.3V / +5V power supply voltage regulator extension pin headers for each uC pin four mounting holes 3.3 mm (0.13 ) GND bus Vcc bus FR-4, 1.5 mm (0,062 ), green soldermask, white silkscreen component print dimensions 100x80 mm (3.9x3.15 ) Page2
