TPM 1.6 has specific vulnerabilities and quirks not present in 2.0. For instance, the authorization mechanisms for NVRAM indexes are weaker, and the "Dictionary Attack Lockout" logic is less sophisticated. Security professionals use the RPC8394 to audit these legacy systems without risking a permanent lockout of the chip.
Note: The RPC8394 appears to be a specific OEM or industrial control component. If this is a typo or a less common model, this guide focuses on the general architecture of a and how it would be implemented in such a device. RPC8394 1.6 TPM reader

From a software perspective, the reader typically requires specific drivers provided by the OEM. While Windows 10 and 11 generally prefer TPM 2.0, the RPC8394 can still function for basic encryption tasks on older operating systems like Windows 7 or specialized Linux kernels (using the tpm_tis driver). Why the 1.6 Specification Matters
With a standard software tool, you only see the final hash (e.g., PCR 7 for Secure Boot state). With the RPC8394, you can trace the extend operations —the actual sequence of events that created those hashes.
