I have to be careful this time. I lost the last project because all the information I fed to the customer ended up with the competitor. Of course, I have no idea what the competitor is using, but something like M2 for sure.
I feel like the new Marco Polo, discovering the new electronic wonderland. I found at least three sources of M2 like chip. The first source requires external LDO and OPAMP, but the total BOM is still cheaper than the second source. I am still waiting for response from the third source.
I believe this is the 4 bitter everybody is thinking about, except it look and feel like 8 bits 6502. They are remarkably similar but different. It could be coming from a central design source.
