Welcome to the Infineon Developer Community

Hello,

I was wondering if the Co(tr) is also available for other FETs/Transistors than GaN and SiC.

Additionally, I was wondering if Co(tr) can also be used for voltage levels, which are different to the voltage level used to determine Co(tr). For example, Co(tr) was determined by loading the output capacitance from 0 to 500V, but the voltage level used is only 300V.

This is my understanding of Co(tr):
The fixed capacitance Co(tr) is used to capture the relationship between charge and voltage of the discontinuous output capacitance. Here, the equivalent capacitance Co(tr) is determined by charging the output capacitance at a current i and a voltage V, and thus describes the time-related effective output capacitance. Thus, Co(tr) can be used to determine the charge/discharge time of the output capacitance Coss independent of the topology.

Best regards

Hi

目前我这边遇到一个项目，是改变金属弹片和 PCB 上 sensor pad 之间的距离来检测动作这种方式。然后我发现拨动一个方向时，4个sensor都会检测到信号量变化，2个增加，2个减少。不知道有没有什么经验可以分享一下。我该使用哪些函数去识别我想要拨动的方向。附件是硬件图。

你好，

背景：我这边使用TC397实现I2C 读写时候出发了Trap，对I2C操作分布在core0 与Core4

发生Trap 后对应的信息如下

DATR 寄存器的SBE 置位1

DEADD 寄存器显示F00E8000

请问发生这一故障的原因是什么 ？如何复现

Hello everybody,

I have a short question bout the PSoC 4: Is it possible to extend the flash ROM, so that the program is not started form the internal flash as in the picture below but from a EEPROM from an IC?

The background is that I am working with the PSoC 4 Pioniee Kit CY8CKIT-042 and I have not enough memory for my application and cannot compile it. I would like to expand the memory with an EEPROM with 64 kbyte for example. 

Best Regards

Good day.

I have the OPTIGA SLM9670 Iridium evaluation board, which can be used with a Raspberry Pi 4.
My client has requested that we need to build a CM4 carrier board, with the TPM included.
I have designed the board, for using the TPM on SPI-3.
While the driver picks up the TPM, the TPM then withholds communication, and the driver thinks it is a v1.2 TPM, not a 2.0 TPM.

dmesg:

[ 8.184064] tpm_tis_spi: probe of spi3.1 failed with error -62

It is not a SPI/GPIO line misconfiguration, this happens, irrespective of pullup/pulldown.
This TPM works with the SPI-1, and enumerates on the system as /dev/tpm0 and /dev/tpmrm0

Hi,

I am working on bringing up a custom board. We have a lot of experience with the IMC101TF048XUMA1 and have integrated this into our design. I am using a iMotion-Link to attach a PC to the board for programming. I am trying to establish the initial communications and to program the initial Firmware onto the IMC101TF048XUMA1.

I can see the UART signals (0-5V) arrive at RX0, pin 45 on this part, but there is no response.

I have also verified on an oscilloscope that the signal is as expected. It arrives at the pin with clean transitions, and I used the same 'scope to verify the UART signal as a series of 4 bytes from MCEDesigner - as you can see on the plot below. Here you can see the incoming signal on the bottom trace. Of course, to look for the response I also zoomed out and looked to the right and found no response from the TX0 pin 46, nor did the MCEDesigner app connected to the port.

One thing I did notice is that the pulses measure at an equivalent of 113.2kBaud rather than 115.2kBaud. This is what the iMotion-Link generates. Is this enough to cause the signal to be rejected by the IMC101?

Any thoughts on any reason why the  device might not respond to this signal?

Here's a schematic snippet for reference. We are using 5V for power, and power is applied to the board.

Can you share the Circuit schematics, BoM, and PCB layout of the CCG7D automotive rear seat charger (RSC)
solution demo (SD2211) kit test report since we required it for our project understanding

Dear,

I want to use I2C to ready CYPD3177's register, do you have the sample codes for how to read a specfic register?

CYPD3177 slave address: 0x08

Register address : 0x1400

expected return value is 0x02 (success)

Thanks.

Dear Sir :

Used PSoC Creator 4.4 & EZ-PD CCGX DOCK SDK , change device item  -> generate application have some errors.

Please help us to fix it , thanks.
