First question asked Welcome!

Hallo,
I'm looking for an alternative of the Mb90f347caspf-e1. Let's have a look to the part number

Now it is called CY.. (Cypress). The "34" is the family, '7' indicates the memory (64K Flash, 6K RAM). Ther parts with  a '3', '2' and '9'  has more memory (really? only more memory?). They should work. 'c' and 's' are some functional options. "pf" is the case, isn't it? What is the meaning of  'a' and "-e1"? Will my Programm run on a Mb90f342cespf ('2': more Memory -> no problem, 'e' instead of 'a': what is that?).

Or easier for all: Is there full part numbering table of the MB90 (CY90) family available?

Best regards

Hello Galtimaren,

Please refer to this discussion for the part number decoding for this part - https://community.cypress.com/t5/Knowledge-Base-Articles/Meaning-of-Legacy-16-bit-32-bit-Auto-MCU-Pa...

CY90F340E (family of Mb90f342cespf)  should be the enhancement generation of CY90F340(family of Mb90f347caspf ),  "a" to "e", sorry I don't have the detail on what is changed/enhanced, you may refer to the datasheet of the devices. 

For available CY90 part, a reference can be https://www.cypress.com/documentation/other-resources/cypress-semiconductor-leadtime-guide 

Anyway, these are legacy products,  recommend migrating design with new products https://www.cypress.com/solutions/automotive-solutions when possible.
