STC Microcontroller Reply  
A lot of STC make microcontroller like STC10Fxx are not supported in Wellon GP-20.Are you going to implement these microcontroller with GP-20?
Last post : Re:ST62T25C Reply: RobM90
Thanks I could program three mcu"s, but to get it, I had to program many times each one. Other detail, I can"t protect the device with bit protection, since doing so the device is damaged.

I tried to program the device in two steps, first the file source and then the bit protection, but I had no success and I don"t know if this is possible in OTP device.

VP-390 Reply  
I am using the VP-390, but it"s not working well.
I plugged in the programmer and then open the software. Then the following message pops up. I followed the instructions and reconnected the USB port or even reboot my computer for many times. It just happened to succeed once. The next time, it fails again.
That time it was able to connect, the programmer can only read from the chip but failed to write. I am setting the chip model correctly, because that"s what I use in VP-20.
Last post : Re:VP-390 Reply: hexxx309
I fixed the problem by using the 32bit version software, although I am using 64bit win7.

Hi, I have a s29gl032N90ffis2 programmed and locked. I need erase it. It′s possible ?
How to read the configuration bits prevent the delete.
How to clear it.
Last post : Re:V890 Reply: jin
This chip has a secured silicon sector which has 128 words. The 128 words are OTP, can"t be erased. You can read the 128 words, and they are in buffer address 400000H---4000ffH. Except the OTP sector, you can erase the chip normally.

VP-480 Reply

Using a VP480 (works very well!!).


1.Is there any way (.ini file?) to start software and have Insertion Test not enabled? Sometimes must uncheck this box because programmer shows device failure (device is good...with Insertion Test off, can write and program device OK) If so, how?

2. Is it possible to upgrade my VP480 to VP590. Maybe purchase the VP590 motherboard by itself. If so, how can I do this?

 Sheh sheh and regards...Steph
Last post : Re:VP-480 Reply: jin
1.There’s no way to start software and have insertion test not enable. Because most of chip need to check the insertion test. If some chips poor contact, the chip pin may be damaged. So insertion test must be default.
2.It can"t upgrade the vp480 to vp590. There hardware is completely incompatible.

Programming Lattice GAL16V8 Reply  
Hi, I’m having problems programming Lattice GAL16V8 parts.

I have a VP-880 and, I’m using Atmel’s WinCUPL.

My jed files that wont program Lattice GAL16V8s. However, the same jed files used in a Advin 240 programms these parts OK. Other manufacturers parts programme OK e.g. VLSI, ST, Nar. Semi. I found that by selecting Nat. Semi. as the device type I could program the Lattice parts OK!

Thanks - DaveH.

I sent the files you requested on the 12-06-13 but have not heard back. Are you still looking at this issue?

[ The message is modified by DaveH ]

Well, unfortunately, it doesn"t work on my VP-880! I"m using the latest Windows Wellon software version 4.3.4 (you advised that this was the latest s/w that supported my VP-880) - If I select Lattice the GALs (GAL16V8) don"t program correctly! If I select NS (National Semiconductor) they do program OK? I have a friend who has programmed a few of my Lattice parts for me, using his VP-290. Once I"ve got them back and tested them I"ll report my findings here.
Thanks - DaveH

programming 29LV160 tmc-90 Reply  

I have the VP-390 and i want to program the 29LV160TMC-90 44 pin SOP. My programmer will only program the 48 pin TSOP 29lv160. The only difference i see to the SOP compared to the TSOP is the 44 pin SOP does not have the RY/BY# pin.

if i make an adapter for the SOP to match the pinout of the TSOP and use the 48 pin TSOP mode to program the SOP will it work ?

Could you please add suppport for reading generic (P)ROM devices like: 2332 2364 23128 24256

They are ALMOST pin compatible wth 27xx eprom series, and can be read using small pasive adapter as 27xx eproms. Other programmers can do that.
