Flashing MX29LV160TMC with MiniPRO TL866A/CS/II guide

There is also an adapter PCB for this on oshpark so you don't have to cut any traces: https://www.oshpark.com/shared_projects/cyvjThOk

 

Way too expensive; sure you get 3 but who else is going to have this issue to want one. Also the header is female on the SOP44 adapter so you'd have to order a male header and I just don't see the point of that board even existing at all really, may as well spend $15 more on a proper programmer that supports it rather than having that board fabricated and assembled.

Anyway thanks for making this tutorial as it was likely made for me, I'll give it a try later today. I tried something similar but not cutting any traces. I have no other use for it so I'll give it a shot even if it doesn't work.

It'll say it reads it (empty) and erases it, but it won't let me program anything to it even with Chip ID and Pin Detect disabled. Are you using the Plus II this time?



I appreciate your help, but something must be wrong on my side. I don't have the option to check the adapter from the directions you wrote. I'll just buy a different programmer eventually most likely. I'm sure someone will be able to make use of this information if your non-PlusII is working with this hack.

 

your SOP44 adapter is for obsolete 28F100/200/400/800 29F100/200/400/800 series EEPROMs (8Mbits at max). just compare pinouts of MX29F800 and MX29LV160 in SOP44 package and you will understand why cuting traces 1,43,44 was necesary. the adapter is compatible with all minipro revisions. there is no need to disable chip ID, just select proper chip. MX29LV160T TSOP48 for MX29LV160TMC or MX29LV160B TSOP48 for MX29LV160BMC. i don't see any issue with modifying adapter, i can buy another one since they are relatively cheap. and yeah! you can buy "proper programmer" for a couple of hundreds or deal with Willem Prog and LPT-port xD. for me sub 15$ bucks is fair price to pay and forget about "piggyback" and GD-ROM.

 

i don't think this one is a proper alternative since its just naked PCB and you have to purchase separately SOP44 ZIF socket to make it work ))

 

I was referring to the OSHpark adapter by the way.

 

yeah! my bad ))

 

You either have to cut the traces of pins A19, WE, Reset and rewire them manually like shown in the first post or put the oshpark adapter in-between the SOP44 ZIF PCB and the TSOP48 adapter. You cannot just plug an unmodified SOP44 ZIF PCB directly into the TSOP48 adapter as both have a slightly different pinout.

See here on the left side. Pins A19, WE, Reset are in the wrong place:

MX29LV TSOP48 pinout:


MX29LV SOP44 pinout:




Irrelevant to this topic but in case someone ever needs them, here are some other pinouts:

AM29F032 TSOP40
