We are getting massive ammounts of emissions from the D0 SDIO pin with 120mhz and resonant freqs. The pins for SDIO have been set to AF but nothing else has been setup register wise yet, the circuit was taken from the appnotes with the 3v3 pullups on D0,1,2,3,CMDAPB2 periph is 60mz APB2 timer 120mhz

Hello, I have a PC system with specific issues to boot with some SO-DIMMs. one of the diffrence between working and non working SO-DIMMs is the Marking on the SPD Chip.One has EBTF one BBTF marking. Based on internet searches I think to know, that at least EBTF is a M34E04B SPD EEPROM. So far I have not found the decoding what means EBTF vs. BBTF. Does anybody know how ti figure out the difference ?Hermann

Hi,We are using MPC5xxx uC and configured single SPI channel for 3 different devices. One of the device is EEPROM (M95256-DRE) and SPI channel is configured as 'Synchronous' mode.Issue : Before configuring the SPI channel for EEPROM, the two devices were able to successfully get the transmit / receive the data via SPI channel. We tried testing the EEPROM independently and we were able to read / write the data from / to EEPROM successfully (Here the other two devices functionality was disabled).When all the 3 devices functionality is enabled, we observed the below issue :Scneario 1 : When EEPROM alone is requested to transmit the data we are able to receive the data from EEPROM. Scneario 2 : Sequentially we are utilizing the SPI channel to get the data from EEPROM and other devices in below mentioned sequence. Step 1 : Send command to get the data from EEPROM. Here we are getting correct data.Step 2 : Send command to get the data from other devices. Here we are getting correct data.Step

Parts:ST1284-01A8RL-E，What does this "e" mean?We are eager to know the difference between "ST1284-01A8RL" and "ST1284-01A8RL-E".

HiWe are using 95128-A125. It's datasheet provides "write cycle endurance" numbers for various operating temperatures. But there is a note that reads "The Write cycle endurance is defined for groups of four data bytes located at addresses [4*N, 4*N+1, 4*N+2, 4*N+3] whereN is an integer, or for the status register byte". Is the "status register byte write" considered as one write cycle regardless of address? For writing to any location within the EEPROM, we have to write to status register first (to set the bit WEL). Suppose we perform the following steps:Write to status register to set WEL, then write 32 bit data at address 0x0000.Write to status register to set WEL, then write 32 bit data at address 0x0010.Write to status register to set WEL, then write 32 bit data at address 0x0020.Q1: How many write cycles will be counted for address 0x0000? One? or two (because we wrote into the status register AND wrote to address 0x0000)?Q2: Since we wrote 3 times into the status register (but fo

hello,everyone:I'm using RH-PMICL1AK1 which is Engineering model of RHRPMICL1AK01V , its datasheet If the voltage drop on RSENSE exceeds 100 mV, the device enters the current limitation mode.However,actually only the voltage drop on RSENSE exceeds 125 mV,the device enters the current limitation mode.Is that the same with you？blessing.

Hello,Previously we are using AT24C512 I2C EEPROM(current consumption 1uA in standby),with this our device current consumption is about 4.2uA.Due to more write cycle of M24512-DF EEPROM, we just replaced AT24512 with M24512-DF. EEPROM read and write works perfectly. But in standby mode, our device wit M24512 IC consumes current of about 90-100uA.We doesn't change our any part of code, we only wants to replace AT24C512 with M24512-DF, But it increases current consumption of device. Please help us to reduce this current consumption as M24512-DF datasheet states that standby current of 2uA. So may be EEPROM is not going into standby mode.I have compare At24C512 and M24512-DF Datasheets and they have similar procedure for standby method after stop condition is send, and my code is sending stop condition after read or write complete. But AT24C512 goes in standby mode, whereas M24512-DF not seems to go to standby mode, or any other issue..We used 4.7K Pull up on SDA,SCL and WP. and For Addre

I have just purchased some samples of the ST L9637D from my local supplier, however Pin 1 Is not identified See attached ImageThe following is printed on the ICL9637DGK924Any suggestions woudl be appreciatedThank you

I did not understand that VCC range of the SRC0CS25D is 1V6-5V5 and the electrical specifications state Vth=(min,type,max)=(3v29,3v40,3v50). There is some uncertinity about the thereshold. If my VIN voltage (given to VCC pin of SRC0CS25D) is under 3.40v, the chip does not operate properly? There is someone who helps me?

I'm specifically interested in PSD813F2A-90MI. Is it possible to get the last released statements?

It is for a veglia boreti automotive instrument cluster from a fiat punto 2001 - 1999Hi there! I wanted to politely ask for your help, if you can answer a simple question: i have a 950406 k128 eeprom chip but cant find one to buy online i only can find 950406 K506W or 950406 K304K, if so can i use these other ones to replace the 950406 k128

I have downloaded the Verilog model, and testbench, but I can't make any sense out of the source.

Hi thereI've recently started working with st10f275 microcontroller. I am totally confused. I can't event find its datasheet! which compiler, ide, programmer should I use?Could anyone guide me? Thanks in advance.

Hello can i ask a question? I want to read hex file via stm32 but without using any interface. Thank you very much if you can help.

Tks for your reply.

Just want to make sure such dual/ghost marking would not have any adverse impact to the parts quality.

Hi,I have issues to get the source PDO capabilities by STUSB4500. My power source has 4 source PDOs as below:5V, 3A9V, 3A15, 3A20, 3ABut I most time got below:5V, 4.19A9V, 2.88A15, 3A20, 3AVerifying the PD message registers, I got: 0x30 1  2  3  4  5  6  7     8  9  a  b  c  d  e  f 00 66 07 7D 4B 1A EC 20   D1 02 00 2C B1 04 00 2C 41 06 00 ED F1 E2 0C 00   00 00 00 00 00 18 E3 00I picked up the message register data as below0x33 7D 4B 1A EC <---  PDO0 data is stored here temporary0x37 20 D1 02 00 <---  PDO1 data is stored here temporary0x3B 2C B1 04 00 <---  This is 15V, 3A for PDO20x3F 2C 41 06 00 <---  This is 20V, 3A for PDO3I think my register reading may not be fast enough, but from USB-C PD sniffer, I cannot find any PD message that can overwrite the register 0x33 to 0x3A.
