Hello. I have some CY7C64713 (100 terminales) chips and I was looking at the CY3684 USB 2.0 DEVELOPMENT BOARD schematics. But as this chip does not allow external EEPROM programming I was wondering how I can reduce the circuit to make a simple programmer and start testing it. The circuitry needed to use the USB port would be enough for now, so I can use it to download the code to the 8051 core. Thank you for your help.
i didn't understand what you meant by this chip does not allow external eeprom programming... i mean the device does allow programming of the EEPROM through the chips i2c interface and the required commands can be sent over the usb interface....
Thank you very much for you answer. You are right, I misunderstood "Software: 8051 Code Runs from: External memory device (128 pin package)" in its datasheet. I also have a CYC68013 chip (100 pins), so I could use actual Cypress tools to develop software needed. I would like to know how to move data from the USB port to programm an EEPROM. In order to download the code through the USB cable I need to know what type of transfer it handles when I plug it in (does CyConsole allows me to do that?). And of course what changes I need to do on the schematics attached on my previous post to make a programmer. In case there is other document than the datasheet and techinical guide for those chips which could be helpfull, please let me now. Greetings from Peru.
cyconsole has a LgEEPROM and SEEPROM button which are used to program the EEPROM with the iic file (EEPROM image)... i believe you have attached the schematic of the development kit... it is fine as is.... i mean it is designed such a way that it doesnt restrict the basic functionality of fx2lp...
