E-prom ereaser& burner

[Dr.Acacio]

Good point Shawn !!!!!
I am looking to find here in Brazil some 29C256 to avoid waiting for UV
erasing the 27c256....
Do you know what could be used instead of a 27C512 PLCC Eprom???
Does exist any 29C512 Flash in PLCC.???????
I have tried the 28F512 but is not pin compatible....
To test in my car ( Fiat Marelli ECU) each time I spend a PLLC chip, because
they dont have window...
Many thanks
