Hi, i don't want to know if the 95042U3 is simply an 95040 i don't have datasheet on this eeprom for automotive device. I want to know with which device i can read it or write it.

Hi,

In standalone, you can read/write the device with all "eeprom reader" available on the market.

Hi

Thanks a lot for your reply but which chip need to select because on all device we have 95040 but not 95042UE is it the same IC or not ?

[Pierre P.]

If 95042UE is the top marking,it's unknown to us.

BTW, lot of chance it would be a 4Kbits SPI.

Thx a lot. Just to tell the ref is an ST Microelectronic specific for automotive. You find it on Anti Blocking System Wheel module.

Please, give me all the marking informations. Picture would be welcome for better support.

Hi 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.

It is for a veglia boreti automotive instrument cluster from a fiat punto 2001 - 1999...

It would really help if you answered deeply appreciated.

Thanks in advance :)

95042U3 9332K with ST logo

[Pierre P.]

Hello,

After investigations, this marking doesn't fit with standard STMicroelectronics marking for eeprom 4Kbits SPI in SO8N.

Should be:

1st line: 95040xx (with xx = 2 letters)

2nd line: ST logo + KywwX (yww = year+week and X= 1 letter)

Hi

thx a lot. But i have the ST logo on the second line and this eeprom is present on a break module (Antiblockin Systeme Wheels) from ATE brand for a european vehicle
