I am developing a device using the CYUSB3014-BZXI, and having problem to pass the 2.5mA current requirement on U3 suspend mode. I noticed that the EZ-USB FX3 / CYUSB3014 is listed on www.usb.org as a compliant device.
Could you please let me know: Q1: What is the U3 mode current consumption @5V of EZ-USB FX3 / CYUSB3014 when bus-powered? Q2: Has the EZ-USB FX3 been tested as bus-powered device to pass the 2.5mA U3 mode current requirement? Q3: Has the EZ-USB FX3 been tested as self-powered device to pass the 2.5mA U3 mode current requirement?
Please add these lines before calling CyU3PGpifSMStart API in your firmware. Thsi will add an internal weak pull downs on DQ 14: 8 and add an internal weak pull up on DQ 15 and thus give the pattern 0x80.
Note that, externally these lines (15:8) should be unconnected. Only then these internal weak pullups/pulldowns will come into effect.
