Welcome!

dear all,

i am using CY8C4245AXI-483 in my product. up to date i had used thousand of chips.

i am using miniprog3 and my standard product pcb.

i was using creator 3.1 and now 4.1

i have recently purchased 320 chips and for that i am facing following problems.

i am always using miniprog as 5v, reset cycle, 1.6 MHz.(as my default)

pin no 13 and 14 gets connected to miniprog via 330E resistances.

chip detection by miniprog display for 2 to 3 sec. and get disappears. after removing and again connecting miniprog chip does not get detected

nothing is going hot, failure of usb supply etc

so i checked VCCD voltage it comes to near 200mV from 1.7V. (VCCD is bypassed with 1uF)

XRES remains to zero.

please help.

Hi,    

Make sure that your miniprog3 is still functional. And miniprog3 is not actually meant for production programming.
