i am considering the CY8C4246AZI-L445 in TQFP48 for a design , we want to program this device using a miniprog 3 and the 5-pin connector , unfortunatly the data sheet and cypress technical support SUCKS and so we are unclear on how to wire this up !
on the 5pin connector we are using:
Pin 2 GND, Pin 3 XRES, Pin 4 SCK and Pin 5 SDIO
The pins are wired to the following pins on the MCU :
PIN36: XRES
PIN16 : SCK
PIN14: SDIO
Is this correct ?

So the correct names of the pins on the MiniProg3 are:
1 - VTARG
2 - GND
3 - XRES
4 - SCLK
5 - SDAT
The CY8C4246AZI-L445 is a 64 pin device, I assume you mean to say the CY8C4246AZI-L423 device? It is a 48 pin chip. If so, then yes, those are the correct pin assignments. I verified that by checking the pin assignments in PSoC Creator. (Much faster and easier to see than in the datasheet!)
Good luck on your project!!
