Ponyprog Circuit for AVR & PIC16F84

Schematic

Comments

All resistors are 1/4W.The circuit is powered by 9…15V DC or AC. When In Circuit Programming (ISP) connectors are used, is possible the programmer to be powered from target’s power source. Diodes D2 and D6 protect the regulator LM7805, when target’s power is used.

‘ XTAL JUMP ‘ is used to cut XTAL when the AVR has internal RC oscillator enabled.

‘FAMILY JUMP’ is used to select which ATMEL’s family to program, AVR series (ATtinyXX, AT90SXXXX, ATmegaXXX) or 8051 series (AT89Sxxxx).

‘PIC JUMP’ is used to switch between Microchip’s PIC and ATMEL’s microcontrollers. With jumper ON only PIC can be programmed, while OFF can program ATMEL’s microcontrollers. If you don’t need to program PICs, you can leave their board area unsoldered. The PCB has been designed so that DIP sockets or ZIF sockets can be used. Because of its cost, it is recommended that only one ZIF is used combined with some pin-arrays to switch between the four different places.

The board must be connected to a PC COM port through a 9 pin to pin cable and work with the below application:

Supported microcontrollers are:

ATMEL’s AVR series

ATtiny12, ATtiny15, AT90S1200, AT90S1200A, AT90S2233, AT90S2313, AT90S2323, AT90S2343, AT90S4414, AT90S4433, AT90S4434, AT90S8515, AT90S8535, ATmega8, ATmega16, ATmega161, ATmega163, ATmega323, ATMEL’s 8051 series, AT89S53, AT89S8252

MICROCHIP’s PIC series

PIC16x83, PIC16x84, PIC16F84A

And some other programmable ICs (memories, microcontrollers) which Ponyprog support but need a board adapter to be programmed through ISP connectors. For more information see Claudio Lanconelli site .
