For example, using the reader, you can witness: PCR[0] hashing: 00 00 00 00...+ (CRTM code) = New Hash A

Hardware component used to write or modify data on the chip.

If the RPC8394 is a board-level reader module, it may have a 6- to 10-pin header:

The RPC8394 is not a general-purpose cryptographic token—it is a . This specialization justifies its premium positioning in enterprise IT kits.

Beware of counterfeit or "generic" SPI programmers marketed as TPM readers. Only the genuine RPC8394 includes the proprietary TPM state machine logic required to interpret TCG structures correctly.
