Hi Cypress Could you help to confirm the following questions? 1.What is the purpose of EEPROM? Does EEPROM save Boot code? We found it can upgrade firmware from datasheet, but we don't need this function.... I have scoped every signal. The LED lights and oscillator is running until Windows 10 shuts down the hub after 3 seconds. USB downlinke is internally used, therefore no overcurrent protections. The power supply is st... Hello Ordering Information is on page17 of the HX3PD data sheet (Document Number: 002-16615 Rev. * F). There is a description of "Signed FW Download" in Table5 Ordering Information, but could you please tell m... I understand in USB 3.x, hubs are required to service packets using a priority order: 1) Transaction Packet; 2) Data Packet for interrupt or Isochronous modes; 3) Data Packets for Bulk and Control modes. Does Cypress... Dear Support and Expert We are using CYUSB3326-88LTXI on our product. And we want to test Signal Intergrity on USB Rx lines. Is there any method to enter the USB HUB Loopback mode? We are now trying, ... Hello! Our company recently purchased a CY4609 interface development board through the authorized CYPRESS store. The power supply was overloaded accidentally and the rated voltage was 5V, but the actual use was 12V. C... Hi all, I am working on Cypress cyusb3014-bzxi chip. However when I connect it to the computer, I am unable to detect the device. It doesn’t show up anywhere in device manager also. Do I have to do some... I was asked about USB2.0 Hub CYUSB2304-68LTXI. 1. What is the actual threshold of VHSDSC(Disconnection Envelope Detector)? They know that the min & max VHSDSC values described in the U... Based on the 3.1 Standard (Table 7-7), the PENDING_HP_TIMER has a 3 us value. However, I see certain cases that Cypress Hub violates this timer marginally by about ~100-200ns. In our test setup, these recoveries... Hi Cypress DevCommunity! I am currently running into the following situation... Hoping that I can get some help on pinpointing the root cause. When a device is hot plugged to the downstream port of the... I am searching for i2c code when cyusb3314 is in slave mode and I can configure individual port power control ,Please share Linux i2c sample code Hi All, I am trying to use a CY7C67200 USB control chip to enable communication between an FPGA and a host computer. The reason I am using this chip is that it is pre installed on the development board I am us... I want to know CYUSB2304's I2C AC specs. However, there is no description of AC specs in "HX3 USB 3.0 Hub datasheet(001-73643 Rev.*R)". I think it is equivalent to "PSoC Creator Component I2C Master/Multi Master/Sla... Hi Cypress Whether have design issue When We only connect USB3.0 pins in CYUSB3314 circuit Then let USB2.0 pins don't connect anything and keep open , Thank !! I reinstalled and repaired the SDK several times but the header file is not able to be resolved in the source code. This header file is not present in the workspace, it is an inbuilt include file. How can I solve the ... 大家好， 具体问题：系统中usb传输通道与uart通道同时存在，希望能够快速切换这两种数据传输模式。请问有什么合适的芯片推荐吗？谢谢大家！ Hi All, We are working on NXP'S imx8 based custom design. we had interface cypress's CYUSB3304-68LTXI USB hub. It is working fine with SOC. We need to change the drive strength of the USB HUB. So, we have fol... Hi, we are designing a new USB hub, and I have a question about the #PWR and #OVR pins. If our downstream devices are self powered, is there any problem with bypassing the #PWR and #OVR pins? I am planning to leave th... Hi, we have charging problem with CYUSB3328 hubs. Expectation: At startup we want to read out cypress settings. We want to verify that correct set of settings are in use. Then we want to charge phones with 1,... Hi, I'd like to use CY7C65632/42 for the project. I see there's LED control pins on CY7C65632/42 series But I'm wondering - 1. What is the default control behaviour for GREEN/AMBER? 2. Can you control the L...
