Schematic and description of an A589-compatible PIC programmer

How it works

The circuit which is presented here is based on the circuit presented in the Microchip Application Note 589 (AN589). This programmer is compatible with every software supporting AN589 programmers.

The programmer is connected to your PC with an usual parallel printer cable. I use the software PBrenner under Windows 98. Please note that in some notebooks, only cheap hardware is used, so you could get into trouble running the programmer with such hardware.

A H signal on D4 turns Q2 on, resulting in /MCLR going low (the PIC is reset). The reset condition is ended by setting D3 to H and D4 to L (Q2 is off, T1 and Q1 are on). A simultanous reset and programming mode are prevented by connecting the emitter of Q1 to D4. For correct working, it's sufficient to connect the programmer to 12 V. Data and clock signal are connected to D0 and D1. The data which is read is available on ACK. BUSY and PE are connected to ground.

The IC1 buffer is activated during programming by D2 and D5. During reading, D2 is set to L.

The resistors are needed to create the necessary logic levels.

You can use the 5 pin connector to program a PIC in its target circuit. This is called ICSP (In Circuit Serial Programming).

Software

I use PBrenner under Windows 98 by sprut.de. But every other AN589 compatible software should work as well.

In Use

Component list

1 x IC socket 40 pins
1 x IC socket 20 pins
1 x IC socket 18 pins
1 x IC SN 74 LS 244
1 x Voltage regulator 5V 7805
1 x Transistor 2N3906
2 x Transistor 2N3904
4 x Resistor 2,2 k
1 x Diode 1 N 4001
2 x Electrolyte capacitor 47 µF

Part list as PDF document (57 KB).

Looking at the photo you see that's also possible to use a standard centronics connector.

oh very sorry just that i want to send you something and it's done wrong.
i need a programmer circuit schematic for various kinds of pic such as pic16f84 i want to make it by myself ...

please help!!

The AN589 was a very obscure design, and hardly any software supports it. Luckily David Tait released a popular design that has improved and grown over the years, and most software supports David Tait style designs.

Check my website for programmer circuits and suitable software, the P16PRO40 is an updated David Tait programmer.

AN-589 is supported by Ic-prog, the PIC programming software which has quite a large user base.

Can't comment on whether AN589(by Microchip, the PIC manufacturer) is an obscure design or not as I am not very good at circuit design.

I found that programmer from website: http://elektronik.kai-uwe-schmidt.de/

It was written that this schematic is dessigned for AN589 but i became very surprised when they indicated in the next diagram that we could also place PIC16F84 or pic16f878 , i didn't know how that

eblc1388 · 3rd August 2005, 04:20 PM

Forget what you have found on programmer design.

You should really follow Nigel's advise of building the P16PRO40 which is a good design, well tested, use by a lot of people and supported by many PIC programming softwares.

You can't go wrong with that.

OK , that'll be fine, i'm going to learn about pic from nigel's site only.
