I need Application Note for pins connection.
I developed a test circuit for my application, but it doesn't work.
I have buy Dev Kit and my firmware work well.
I think I have hardware problem, and the chip dosen't work.
I can't find any App. Note for to use this chip.
Topic moved to "Microcontrollers" forum by moderator.
When I plug-in my circuit on the PC (without eeprom), I open Cypress Control Panel (ver 2.61[700]) for download my firmware, but a message box say:
"No Cypress USB device detected".
How you can see, I use CY7C64613-52pin:
- 43pin (RxD0) for recive MIDI signal
- SDA,SCL for EEPROM
How can I connect not used pins?
WAKEUP# , AVCC, AGND, CLKOUT, XCLKSEL, XCLK
RES pins, not used I/O pins.
I can see some difference between Dev. Kit Main Board and Datasheet.
AVCC, must be connected to 3.3V, you should also connect 100nF and 2.2uF capacitors between this pin and AGND. If XCLKSEL is low (like in yours design) you don't need XCLK. AGND can be connected to GND. Try to add 100nF capacitors between each VCC and GND.
Remember that AVCC is suppling analog part of the chip. This is good doc about, how to design PCB for High-Speed USB: h--p://www.cypress.com/cfuploads/support/app_notes/hsusbpcb.pdf
I don't have any experience with CY7C64613 - I was only using CY7C68013.
