PSoC 4 MCU

[Anonymous]

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!!
