Hello, I was wondering what is needed to reprogram the CY22393. It came programmed with the default serial address of 69H, but I need to change the address to something different for project use. I also have questions on the set up, reading back, it looks like I2C programming can only be used for volatile memory. Will i need to pick up a programmer to reprogram the serial address? Also, any tips and tricks to help me get started with reprogramming the CY22393 device would be greatly appreciated. i couldn't only find posts about this product and my specific issue unless they were from 2008-2009. so i wasnt sure how valid those post still were.
Thanks for the help.
I am trying to read and program the CY22393FXC, i need to get a programmer that is able to do those operations but im not sure which one will be the best for my needs. Please guide me on good programmers for this device.
How can I program the CY27410FLTXI with I2C? In the jic file created by Clock Wizard 2.2, it is unclear what value should be written to which address. Clock Wizard 2.2 cannot be used because the program is not a Windows environment. Please give me some advice.
This is the project that was sent to me in the previous question. https://community.infineon.com/t5/Clocks/CY27410FLTXI/m-p/331395#M609Show Less
我們使用了 CY51x7 IC，我們嘗試將低頻晶振設置為 LFF 模式。
我們要使用 50MHz 的晶振，我們按照 LFF 晶振的振盪器相關參數設置。
我們發現如果我們使用 XO_DOUBLER_ENB =1（禁用），我們可以獲得 50MHz 輸出，但如果我們使用 XO_DOUBLER_ENB=0（啟用），我們無法獲得 100MHz 頻率輸出。x
我們如何獲得正確的參數？我們在編程規範中找不到更詳細的寄存器信息，如 XO_CAP 和 XO_AMPLICE。如何獲得更詳細的信息？
How should I calculate the power consumption? Is there a spreadsheet that can be calculated?
The data sheet have IDDs. However, the number of descriptions is small and the conditions are quite limited.
What is the output impedance of CY27410?
In the "Test and Measurement Circuits" of the data sheet, the test environment is described as 50 ohms for single end and 100 Ω for differential. Is it this value?
We used the CY2071AF as the PLL in our project, as the datasheet mentioned it should be programmable(EPROM) in the field, but we keep failing in the over-write the code into the chip which may be had the code inside.
1. May you please kindly help us to provide some suggestion how to overcome this issue?
2. Or the CY2071 series are the "one time use" EPROM? Once the programmed, then can't erase anymore?
3. If it the multi-times EPROM, how can we use the way to erase the content?
We using the Cypress FTG programmer CY3670.
Appreciate for your kindly help!
