INTRODUCTION:
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.
AVR-P40-8515 is prototype board for 40 pin AVR microcontrollers with
STKxxx compatible 10 pin ICSP connector. Supported diveces are AT90S8515 and
pin compatible microcontrollers.

ELECTROSTATIC WARNING:
The AVR-P40-8515 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-PG1, you will need RS232 cable, if you use AVR-PG2, you will need
LPT cable, if you use AVR-ISP500, AVR-ISP500-TINY or AVR-ISP500-ISO, you will
need 1.8 meter USB A-B cable.
Hardware: Programmer/Debugger – one of the Olimex AVR Programmers: AVRPG1, AVR-PG2, AVR-ISP500, AVR-ISP500-TINY, AVR-ISP500-ISO.
Software: The serial port ICSP programmer (AVR-PG1B) works with PonyProg
software by from Claudio Lanconelli and the latest release may be download for
free from http://www.lancos.com. The parallel port ICSP programmer (AVRPG2B)
works with AVR ISP from Atmel and may be download for free from Atmel’s web
site.

JUMPER DESCRIPTION:
J1
When 1-2 are shorted – RTS is connected to terminal pin RTS/DTR.
When 2-3 are shorted – DTR is connected to terminal pin RTS/DTR.
Default state is 1-2.
J2
When this jumper is open – LED is not on.
When this jumper is closed – LED is on.
Default state is closed.
INPUT/OUTPUT:
Status Led with name LED (red) – this led is connected to PIN11 (PB0/T0) .
