Hello,
in the moment we experience problems with several circuit boards that implement the CY7C53120E4-40SXI.
Always when we want to flash our product software on the board using the LonMaker tool (Echolon) we receive one of these error messages:
'Cannot communicate with the device' or 'The device is applicationless or is not associated with a program record'.
The LED connected to the Service Pin is blinking slowly. That means that the Neuron Chip has an application but is unconfigured.
May the cause of this problem be that the Neuron Chip (CY7C53120E4-40SXI) does not contain the LonTalk network protocol firmware? According to the datasheet this firmware should already be present on the chip when we buy it. But maybe it was not correctly programmed in your fab?
Thanks a lot for your answer.

I have recently been messing around with some SCR's. I am aware that once you activate the SCR's gate the SCR will start conducting and remain conducting even if the gate is removed as long as the cathode to anode potential difference is favorable. The issue I am having is that my SCR conducts no mater what. I remove wiring from the gate before applying voltage to cathode, I ground the gate before applying voltage to the cathose, either way the SCR conducts. I have bought 10 SCR's (2N6403) I have tried brand new ones with no gate connection, cathode to 5V and anode to ground etc. still conduction persists. I am very confident that the new ones I have tested have not been internally shorted/damaged. It seems which ever method I use I continually get a conducting SCR without having induced it. If anybody has any input on the subject it would be greatly appreciated.

Thank you.

你好！

CY7C924ADX-AI   这个型号经过X-RAY，照射出来是2种结果，正常？有资料表示？

Hi,

1. The data sheet stated that the output terminal (RESET # 😎 of the IC has a built-in pull-up resistor, so an external pull-up resistor can be omitted.
However, the block diagram of the data sheet does not mention the pull-up resistor, and when I look at the circuit symbol, it seems that it shows a constant current circuit. Is there another pull-up due to the resistor?

2. Can this constant current circuit carry a current of 10uA regardless of the load of OUTPUT?

3. If the load at the connection destination is large (impedance is small), will the output voltage be small?
Please let us know if you have a characteristic table or calculation formula for load and output voltage.

画PCB的时候，可以在tle5012be1000芯片底下铺满GND的铜吗，不会干扰吗

Hello All, Me and my friends are build a project and there is a chip which is obsolete that could not find on the market. The part number that we are looking is CY128P160-167AXC. Can anyone give us any suggestions on where to find the chips?

thanks!

Customer has interest about Infineon Chip Antena.

Actually they have a project with SIiLabs MCU with BLE SOC. But they are struggling with Chip Antenna.

Do we have a chip antenna soluton for satisfying Customer.

Many Thanks

Hi,

I am working with a CYTMA525C driver and I have one question.

How can I put the touch panel in low power mode? I guess that It’s activating LOW_POWER_EN, but I tried and don’t work.

I send this array by I2C:{0x04, 0x00, 0x08,0x00,0x2F,0x00,0x06,0x06,0x01,0x01} following the tables of datasheet.

Dear Sir/Madam,

GreenSoft Technology, a leading provider of environmental compliance data management services and software for the global electronics industry (http://www.greensofttech.com), has been contracted by Basler Electric to collect compliance data on parts purchased from your company. Please refer to attachments for a letter of authorization from Basler Electric and a list of part numbers.

Please note that Basler Electric might not purchase directly from your company but via a reseller or distributor. In addition, you may need to collect material or compliance documents from your suppliers such as raw material manufacturers to fulfill this request. Your support to Basler Electric is highly appreciated.

If you think we reach out to you by mistake, please let us know so we will not follow up with you anymore.

For these parts, we will need the following: (Please note – if you think the compliance information can be obtained from your web site, please mark “Web” for those parts in the attached Excel file)

•       Full Material Disclosure (FMD), MSDS or similar document in your standard format if available

•       Compliance statement for REACH SVHC: REACH SVHC 219 or 211 - if you don’t have the REACH SVHC compliance statement from your company, we have attached a compliance template for your reference.

•       If reportable SVHCs are identified, please provide the SCIP data (SCIP – per Waste Framework Directive 2008/98/EC, amended by Directive (EU) 2018/851)

Please also populate the Excel spreadsheet with the following information:

•       REACH SVHC 219 status (whether the product contains any SVHCs [Substances of Very High Concern] or Substances of REACH - Annex XIV). If a product contains any SVHC, please provide the substance name and concentration, as well as future plan to eliminate its use.

Generally, the parts applicable for 6a/6b/6c RoHS alloy exemptions would form an article, such as a pin, connector shell, standoff, screw, or bracket. Therefore, Lead concentration of such parts is likely to exceed 1000ppm at Article level, which needs your further support to provide the SCIP information. However, if you confirm your products are SVHC compliant, please provide the Article Name.

If you cannot recognize a part or it's incorrect, please indicate such in your feedback.

Please respond by November 08,2021 or provide an expected date of completion and we will follow up. We may contact you if any clarification is needed. Basler Electric is committed to providing its customers with products that meet the highest standards of innovation, performance and environmental safety and expects your timely response.

If you have any questions, you can contact me at Ana@greensoft-china.com or call +1 323-254-5961 x813 (I am based in China; we also have someone in our US office that can answer your questions).
