Oops! The fancy new German USB chip programmer I bought doesn't work with the NOS 2732A EPROMs I bought (TMS2732A).

I've only burned one 27C512 chip with it. Very easy to read/write, all software controlled.


Batronix BX32 Batupo ($149 + $60 shipping from DE)

SOLD!

My one is OK with 2732A's Ken...... did you try a "chip identify" ?

I am programmming ST 2732A- 2FI 21v fine with mine...

PorKen

John,

That's why I bought it, because it had several 2732As listed, which was unusual for a USB type programmer.

I requested one 512 chip update from Batronix, which they did quickly and w/o issue. But when I asked for the (Texas Instruments) TMS2732A though they said: "Unfortunately the TMS2732A can't be supported because of its high current consumption, I'm sorry".

TI (TMS2732A)

ST (M2732A)

Looking at the datasheets, the TI uses 657mW, versus the ST 127mA... I think maybe Gerry read the TI datasheet too quickly, and didn't think to divide by 5v = 131mA.

Doh!

John Speake

Suggest you point that out to them, then.....

Wouldn't it be simpler to buy some other 2732A (I bought my St ones from Futurlec) ?

PorKen

I have 120 of them.

So your Batupo burns the STs with no problem?

John Speake

Yes, no problem...

PorKen

Batronix says they've not been able to burn the TMS2732A, although they were able do the Intel D2732A, and the ST. I tried plugging it directly into the computer with a USB adapter, to no avail.

I'm selling this one (I'll throw it on eBay in a few days), and buying a (Pocket Programmer).

OK, Ken, PayPal sent. Thanks.

PorKen

Cool! Thanks Bill!
