Post by thread:[PIC] programming PIC18F67J50, PIC18F46J50?

I have a home made "sort of JDM compatible" programmer http://www.techtir.ie/forums/showthread.php?t=1751 It works with 16F877, 16F877A, 16F876, 16F628, 18F4550 so far. I've used ICprog but now use Vellemann's PICprog2009 programmer software in K8076 mode. The PIC18F67J50, PIC18F46J50 are not on menu (ICPROG has PIC18F6720 and PICprog2009 has 18F4620, 18F4680). 1) Any suggestions how I program PIC18F46J50 (64K, 44pin TQFP) and PIC18F67J50 (128K byte Flash, 64 pin TQFP)? 2) Any source for cheap DIL adaptor for Microchip's 44pin TQFP? I'm told this works http://www.voti.nl/shop/catalog.html?PCB-06 for the 64 pin TQFP I need the larger code sizes, hence the choice of these rather than PIC18F4550 I'm using right now. The lack of internal eeprom isn't a big deal as I have external 24LC512(s).

These are 3.3V only PICs so your programmer may not be able to support it. The programmer may damage the PICs actually. So if you want to use them, maybe the US$35 PICkit 2 is the way to go or some other programmers which properly support 3.3V PICs. -- Xiaofan http://mcuee.blogspot.com

If your programmer doesn't have variable Vpp or isn't specifically designed for the J parts, it is unlikely it can be made to work. ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.

Obviously the target has 3.3V VDD and mix of 3V and 5V pins (many pins allow 5V pullup resistors). I can easily adapt a programmer for 3.3V Data, Clock and Vdd. However there is no point to the HW modifications unless there is Programming software that support "bit-bang" via RS232 handshake pins for PIC18F67J50 and PIC18F46J50. The HW interface issue can be solved easily, if there is software. Or does the PICkit 2 definitely support PIC18F67J50 and PIC18F46J50. If so where is best place to buy it? (Not from North America as Postage Speed and Price from N.A. is just plain silly to Ireland. What is 10 days & 5 Euro postage from Singapore/Thialand/China/Hong Kong is 20 Euro postage and 15 to 20 days from USA. Canada seems worse) At the moment, time is more available than money, so if Windows XP (or Linux) software was available for my existing programmer design adapted for 3.3V, then I'd prefer that route. TXD enables VPP, clock is RTS and Data I/O is CTS/DTR. Changing the two levels of VPP and changing, VPP, Data & Clock levels is trivial.

You can use your JDM to program the PIC18F4550 chip. -- Xiaofan http://mcuee.blogspot.com

At least my "JDM" (having an ICL7660 based VPP PSU from 5V PSU) programs PIC18F4550s reliably. I'll see how much a PicKit 2 really is here :-)

It's only 24 Euro (unknown postage) and Pic kit 3 is 35 Euro. Also 11 May. :-(
