AVR-P40B-8535 PROTOTYPE BOARD WITH 10 PIN ICSP CONNECTOR FOR AT90S8535 AVR MICROCONTROLLERS Features: AVR-P40B-8535 is prototype board for AT90S8535 AVR microcontrollers with following features: - RS232 Tx, Rx interface with MAX232 IC - ICSP 10 pin connector (STK compatible) - RESET IC ZM33064C - Status LED connected to PB0 via removable jumper - 4MHz, 8MHz quartz oscillator - extension slot on each microcontroller pin - DIL40 microcontroller socket - AGND-GND and AVCC-VCC jumpers - power supply plug in jack connector - +5V power supply voltage regulator - 0.1” (2.54 mm) grid - dimensions: 100x80 mm - four mounting holes 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. ICSP interface: The ICSP connector is 2x5 pin with 0,1" step and Atmel STKxxx compatible layout. The PIN.1 is marked with square pad on bottom and arrow on top. ICSP signals are: 1- MOSI, 2- VCC, 3- NC, 4- GND, 5- RST, 6- GND, 7- SCK, 8- GND, 9MISO, 10- GND TOP view PCB board layout: RS232 interface: J1 removable jumper selects where RTS/DTR line to be connected. In position 12 the line is connected to RTS, in position 23 is connected to DTR. Status LED: Connected to PB0 via removable jumper. Oscillator circuit: Crystal resonator connected to XTAL1 and XTAL2. Analog VCC and GND: J2 connects AVCC to VCC. J3 connects AGND to GND. RESET supervisor circuit: IC ZM33064C with 4.6V threshold. Programming: To program AVR-P40B-8535 you need serial port or parallel port AVR-ICSP programmer dongle (Olimex part # AVR-PG1B or AVRPG2B). The serial port ICSP programmer (AVR-PG1B) works with PonyProg software by from Claudio Supported devices: AT90S8535 and AT90S4434 microcontrollers.
