Hello,
We are using a CY8C9520A-24 on one of our boards and we have several issues with it.
When we try to set the Port0 Bit6 from 0 to 1 the component is rebooting and every GPIO comes back in the default configuration set in the EEPROM. On our board, this pin is driving 3 enable pins from 3 LDOs. These pins only require a few µA to be driven, we are far from the current limit of the CY8C9520. We even tried to switch all the other GPIOs of the component to High-Z, to be certain that other pins were not consumming any current but the result is still the same.
Here is the schematic of the parts involved in this problem:
Do you have any clue on what could happen here? What could cause the component to reboot?
Kind regards,
Victor
Show LessHello,
I have some problems with the I2C Communication. I try to implement a communication between µC and CapSense IC. The I2C SCL clock frequency is initialized at 100kHz and current the µC waits 2s before it starts the communication. Also I try 350ms or 1s or 15ms or 915ms(T_I2CBoot and TBOOT_SYS). But always the CapSense IC sends NACK.
Show LessWhat is the recommended method to create a .JED file for CY25100 parts?
If CyClockWizard is the only option, is it compatible with Windows 10?
When attempting to run setup.exe after downloading from https://www.cypress.com/documentation/software-and-drivers/cyclockwizard-10?source=search&keywords=cyclockwizard, a PopUpBox appears with the following text. Upon hitting the [OK] button, setup appears to exit.
CyClockWizard 1.0 requires that your computer is running at least Windows Vista 32-bit or Windows XP 32-bit SP2 or Windows Server 2003 32-bit SP1 or Windows Server 2008 32-bit or Windows 32-bit SP4 with IE 6.0.

P.S. There was a similar post stating CyClockWizard 1.0 is the tool to use. Reference: @ Re: CY25100; is possible to get a software tool to generate a file to program the part?
Show Less我們一般常見的Tj (Junction temp.) 描述是指積體電路結構能接受的最高溫度,一旦超過這個溫度IC就會損毀
大多規格都是Tj ≧ Tstg,但CYPRESS大多數卻是 Tj < Tstg ,不就表示IC在高溫儲存的時候就有機會損毀嗎?
因此,是否可以協助確認一下Cypress這樣描述的原因?
以下是ROHM半導體對Storage temperature敘述請參考:

最大接合部温度和保存温度范围
最大接合部温度是指半导体工作的最大温度。 另外,接合是指PN接合。
芯片温度高于规定的最大接合温度时,在半导体结晶中生成多个电子孔对,芯片再不可作为元件正常工作。
因此,使用和进行热设计时,需要考虑IC消耗的功率引起的散热或环境温度。
最大接合部温度由制造工艺决定。
保存温度范围表示IC在不工作的状态,即无消耗功率的状态下保存环境的最大温度。
一般与最大接合部温度的值相同。
Hi All,
Im ICT test engineer, is there any programming tools that able to program CY25100 where the device is already attached on board?
as i found out "CY3675 ClockMaker Clock Programming Kit" needs to remove the device in order to do the programming.
preferable the programming tools to have Batch file for execution.
thank you so much!
Regards,
Jan
Show LessBringing up a board and testing the connection to this device, which we have configured for slave address 0x20. It is acking its address but is transmitting a value of 0xFF for the contents of the device ID. Is there something else that must be done to read the register?
Edit:

Hello, what do you have for DSRC ? Thanks!
Hi,
we are using a capacitive touch sensor for our application.
The design is attached below
The capacitive touch sensor has a 2.5 mm thick ABS sheet above the touch sensor.
Could you please suggest any capacitive touch sensor IC's ?
The dimensions of the design are
- the diameter of inner circle ( button) is 16mm
- The spacing between capacitive pads are 0.9 mm
- length of the pads 9.27mm
- area of each pad is 70.84 mm2
Thank-you
Warm Regards

Show LessHi,
Is it possible to add a fixed DC offset voltage to the clock output?
If yes, which part of the JEDEC file should change?
I am using this PLL to have 24MHz+-2000ppm at the output.
Thanks
Show LessHello
I wrote data in I2C using PSOC in CY29411, but no signal was output from either CLK_P or CLK_N.Please refer to the attachment for details including questions.
Q1) Please tell me why there is no clock out from CLK_P and CLK_N?
Q2) When the information of only the setting written in the JEDEC File is written to CY29411 by PSOC I2C, is the CLK output automatically started? Or is there any other settings to start CLKs?
Best Regards
