Hello everyone, this is my first time here so please have mercy on me. I have two (What I guess) Mikrocontrollers and I can not figure out what exactly are: Mikrocontroller 1 with 80 PIN (Printed Information): -------------| IM | CEWE E808 | 9167 51 WF F | 072432000 | -------------| Mikrocontroller 2 with 100 PIN(Printed Information): -------------| IM | CEWE E740 | 9161 51 WF F | 072155001 | -------------| Could someone please explain me what are these two and where can I find Datasheet for them. Kind Regards Michael

No guarantees for anything, info may apply to your devices, or not. And I often just glance over the contents Michael B. schrieb: > what are these two Well I found an IC with "ceve", see attached image. Second line "0061 53 HF F", same structure as yours, last line same number of digits Micronas seems to have marked their automotive microcontrollers with "ceve",cdvn,cdvs ect. In the attached image you can see the corresponding data in the chart. Here the source in Wayback, dated 2003, not much data on that page however https://web.archive.org/web/20030212091925/http://www.micronas.com/products/overview/automotive/index.php Image sources https://www.eevblog.com/forum/repair/can-someone-help-me-identify-this-chip/ Beitrag "Prozessor Information (Datasheet)" https://forums.lr4x4.com/topic/106418-td5-instrument-retrofit-fuel-shows-max-faulty-speedo-fix/

Although better, of course, if you provide the aforementioned pics for users here, and possibly some kind of context information
In case info still welcome/needed Steffen E. schrieb: > Micronas seems to have marked their automotive microcontrollers with > "ceve",cdvn,cdvs ect. Micronas acquired(ect.) ITT Semiconductors in 1997 Michael B. schrieb: > IM | > CEWE E740 | So perhaps you mean "ITT Ceve E740"(?) Here somebody writes "ITT CEVE 740E" (VW Golf 4 thread) https://vwts.ru/forum/topic/128237/post-1721180 So considering ITT Semiconductors was acquired by Micronas, this chart from previous post may still apply https://www.mikrocontroller.net/attachment/624020/screenshot_micronas_CDC08x.png Here just as a visual example(!) an image of different mcu, an "ITT CVDS E440" https://vwts.ru/images/repair4/157053_09.jpg
