We are an IC programmer manufacturer, and we are trying to support ADSP-BF518BBCZ4F16 for one of our customers.
However, we are facing technical issues while developing ADSP-BF518BBCZ4F16, need your help to provide some suggestions.
Firstly, the attached picture is our socket adaptor circuit, please help to check if there is anything need to be modified.
Secondly, We used SPI mode to send read ID command (0x9F) to the IC but got no response from the IC. Do you have any idea with this issue?
I've moved the thread to the Blackfin Processors subforum.
Someone here can better guide you on your question.
Hi,Can you please state that how much voltage you are feeding to the VDDINT. Please note that all domains must be powered according to the appropriate specifications table for processor Operating Conditions (page no 22) in ADSP-BF51x data sheet that can be find in below link.www.analog.com/.../ADSP-BF512_514_514F16_516_518_518F16.pdfRegards,Anand Selvaraj.
Thanks for your message.
VCCINT=3.3, based on the circuit that I attached, is there any other pin need to be connected?
Hi,Please note that VDDINT is the internal supply voltage that's minimum voltage is 1.14v and maximum voltage is1.47v for Industrial Models. BTW, VCCINT=3.3 is not shown in the schematic you provided.I would suggest you to refer the ADSP-BF518F EZ-Board evaluation system manual provides instructions for installing the product hardware (board). Please find the link in below,www.analog.com/.../ADSP-BF518F_ezboard_man_rev.1.3.pdfRegards,Anand Selvaraj.
