[tps_star]

hi ezo
1:most device need how vpp and vcc volt ?
2:0 to 30 volt for vpp and 0 to 8 volt for vcc is enough ?
i need know usually how vpp volt and vcc volt used for most device ?
for example : vpp 3.6 , 5 , 9 , 12 , 12.7 , 15 , 21 ,25 or vpp 7volt existent

ezo please help me
i need dc to dc converter same as true usb programmer

[Ezo]

I do not have a true usb programmer schematic.
Looks it is MC34063 based where output voltage resistors are switched.
Your task is complicate. At first - what will be your programmer power supply ?
You are not able to have DC-DC converter from USB 5V to 21/25V for reliable old EPROM programming . USB is not able to provide such current without voltage drop and overload.
Is it necessary to create Vpp at level 3.6 and 5V, usually Vpp=Vcc selected ?

i will use +5 usb for most device and +12 to +15 for old eprom for this i use external adapter
for universal programmer this voltaj is enough
Vcc : 1.2v,1.8v,3.6V, 5V, 5.5V, 6.2V
vpp : 3.6V, 12V, 12.7V, 15V, 21V, 25V,26.5v
or i need have another volt for vcc and vpp if i need please give number of volt ?

You are so fast in copy/paste. Why do not learn from available schematics ?
Why do not use original datasheets and application notes , other documents to start yourself ?
