I was looking for a TPM 2.0 module for my Gigabyte Z87MX-D3H and I found that the brand of the module is not important.
The ones I found are:
What is the difference among the first three? I guess the last one is identical to the second one, but I cannot find any information about the TPM/FW3.19 vs the TPM-L, both 20 pins.
The naming of pluggables TPM-cards should be something like TPM-L-R2.0, where the L stands for the pins and it's spacing and the R for the protocoll revision.
Please note that on the mechnical part there at least 3 different types. See as well for the electrical part: LowPinCount-Bus (LPC bus).
TPM/FW3.19 is TPM 1.2 compatible and TPM-L R2.0 is 2.0 compatible.
Ok, let me explain again. TPM/FW3.19 (20 pins) is an old module created for old Motherboards like P8B, P9D etc. and it's TPM 1.2 compatible. Asus TPM-L R2.0 20 pin replaces TPM/FW3.19 and is for newer MB like X99-based and it supports TPM 2.0. The last one, ASUS TPM-M R2.0 is for Skylake or later motherboards and it supports TMP 2.0. If you have an old MB with 20-1 connector probably Asus TPM-L R2.0 20 pin will not be compatible with it, it depends on BIOS. You have to check it with your vendor. I guess you understand that you can't use 14 pin module on 20 pin motherboard or vice versa.
The Motherboard Manual will tell you exactly the TPM Module needed, e.g., mine is one you have not mentioned here, TPM-SPI.
It also tells you on the motherboard where the pins are, what version is needed.
The description in the link for the Asus TPM-L R2.0 [supposed] 20 pin states the TPM is a 14-1 package. There's all sorts of faff with Infineon TPMs and Windows updates the last few months.
