Hi,I am in need of the Rise/fall time (or slew rate ) of Switching node of the converter for calculating the Switching loss due to internal MOSFETS.Kindly send me the values corresponding to the following conditions;Vin=3.3V,Vout=1.2V Io=0.8A , Fsw=1.5MHz.ThanksSathish

Dear Sir,I need a datasheet for part number: 1826-6579I would be glad to help me.Kind regardsSaeed

Hello,I have a x-nucleo-idw01m1 and i'm trying to update it's firmware... Reading online i figured out that the latest version is 3.6 but i cannot happen to find the binary image anywhere, all of the links provided are broken.Does somebody still have it? I wanted to contact STM support but the link to the online form is broken as well.Thank you.

How can I download the full datasheet of STHV800.+

Hello,It is stated that the VN340 has conformity to IEC 61131-2.At what manner does it have the conformity? At EMC? At safety? At UL? It is not clear at all from the datasheet and from the site.Best regards,Asaf Abraham

HalloI probably have an EEProm here.SMD TSSOP88PinPrinted on:412R8ST K033Does anyone know what kind of chip this is? Part No.?

Hello,I am a automotive firmware developer.I'm developing using the M24512-DRMN3TP/K product.I have a question.I have used the FM24CL16B (AT24/FM24) model before.FM24CL16B model had 1010+page select in SLAVE ADDRESS.I was able to fully understand the FM24CL16B product.I can't figure out how to page select the M24512 product.Please tell me how to select page.And please tell me the number of pages.Please tell me the byte size of 1 page.I look forward to your reply.Best Regards, Kim

Hi,The bit [1:0] for STUSB4500 registry CC_STATUS(0x11)  is labeled as CC1_STATE: (available when CONNECT_result =1) 00: Reserved 01: SNK.Default (Above minimum vRd-Connect) 10: SNK.Power1.5 (Above minimum vRd-Connect) 11: SNK.Power3.0 (Above minimum vRd-Connect) What is the meaning for SNK.Power1.5 and SNK.Power3.0? What is the meaning for "Above minimum vRd-Connect"?I found that when I connect to a PC USB-A port, CC_STATUS(0x11)  is always 0x11; While when I connect to a lab power supply, CC_STATUS(0x11)  is always 0x13. Is it guaranteed? When USB-C PD is not used, our devices need to be able to power up when connecting to lab power supply(5V, 3A), but not power on when connecting a PC USB-A port. We are trying to find a way to detect the connection type and the CC_STATUS register seems promising.Thanks,Winston

It's from a Hitachi HDD pcb ​110 0a90158 01​

My system is OTG capable- means it can work in Host as well as device mode. The use case is that my system should be able to connect to mobiles and tabs where they are client devices and I should be able to charge them, also being a USB host. Also my board should be able to connect to laptop where I will be a USB client device. I have a load switch on the 5V USB output to disconnect 5V VBUS if I'm working as a USB client device and if I'm connected to a Laptop or any other USB host.FYI, In device mode, the USB IN D+/- pins will will be connected to a USB host at other end and USB OUT D+/- pins will be connected to the onboard MCU in device mode. I was setting control lines to 110 (SDP mode), my MCU is in USB client device mode and is connected to a laptop (USB host). the 5V USB bus is disconnected as the load switch is off. However, I don't have any USB communication happening. If I bypass STCC2540 on the board, it works like a charm. So I suspect it has something to do with STCC2540.

Hello,I am a developer making a product that controls the M24512-A125 EEPROM with I2C.I am positive about the M24512-A125 product.I have a question while developing.I know there is a limit to the write cycles.Please let me know if my analysis is correct.In the figure below, I made a Memory Map as I thought.I understood that at a temperature of 125℃, one memory address can write 600,000 write cycles.Is that correct? I look forward to your reply.Best Regards,

while using flash memory, in case of power cycle the memory gets corrupted.is there any techinique to prevent it or recover it into normal working.

1. If we are using A_B_Side for Super speed MUX selection, whether this A_B_side will be available on followinga) if a USB2.0 or Type A connected to Type C port using a USB2.0 or Type A to Type C connector.b)Whether ATTACH or A_B_Side is suitable for Highspeed MUX selection for pin selection for High speed communication.2.if OTG device is connected to Type C port, will the STUSB block the VBUS to be applied to the peripheral through Type C. (Connecting External Hard disk using OTG in the Type C port)

Hi. I am using STM32F407VGT6 this one and RadioLink SE100 GPS. I am trying to get $GNGGA data via USART and displaying it in putty terminal. I am able to get and print data. After 3-4 minutes gps sensor led is blinking but no data is printed on terminal.

I'm trying to edit a power supply design project that I just recently worked on. However, when I try to open it I get an "Invalid File Format" error. Any idea how to fix this?

Please introduce your Japanese distributor about the socket for M48T86PC1.The shape is PCDIP 24pins. Best regards.

Hi,I have a USB-C power source that supports PDOs of both Fixed type and Battery type. Is there a way to make sink request Battery type PDO?Regards,Winston
