TPM 1.2 TPM 2.0 Architecture A complete specification is intended to consist of a platform-specific protection profile which references a common three part TPM 1.2 library. [5] In practice, only a PC Client protection profile was created for TPM 1.2. Protection profiles for PDA and cellular were intended to be defined, [5] but were never published.
SPI timing diagram for both clock polarities and phases. Data bits output on blue lines if CPHA=0, or on red lines if CPHA=1, and sample on opposite-colored lines. Numbers identify data bits. Z indicates high impedance. The SPI timing diagram shown is further described below: CPOL represents the polarity of the clock.
Low Pin Count interface Winbond chip Trusted Platform Module installed on a motherboard, and using the LPC bus. The Low Pin Count (LPC) bus is a computer bus used on IBM-compatible personal computers to connect low-bandwidth devices to the CPU, such as the BIOS ROM (BIOS ROM was moved to the Serial Peripheral Interface (SPI) bus in 2006 [1]), "legacy" I/O devices (integrated into Super I/O ...
Devices implementing SPI are typically specified with line rates of 700~800 Mbit/s and in some cases up to 1 Gbit/s. The latest version is SPI 4 Phase 2 also known as SPI 4.2 delivers bandwidth of up to 16 Gbit/s for a 16 bit interface. The Interlaken protocol, a close variant of SPI-5 replaced the System Packet Interface in the marketplace.
The Trusted Platform Module (TPM) as specified by the TCG provides many security functions including special registers (called Platform Configuration Registers – PCRs) which hold various measurements in a shielded location in a manner that prevents spoofing.
Universal EXTension (UEXT) is a connector layout which includes power and three serial buses: Asynchronous, I 2 C, and SPI separately over 10 pins in a 2×5 layout. The connector layout was specified by Olimex Ltd and declared an open-project that is royalty-free in 2011, and was used in all their boards after 2004.
The Security Parameter Index (SPI) is an identification tag added to the header while using IPsec for tunneling the IP traffic. This tag helps the kernel discern between two traffic streams where different encryption rules and algorithms may be in use.
6- and 10-pin ISP header diagrams. The in-system programming (ISP) programming method is functionally performed through SPI, plus some twiddling of the Reset line. As long as the SPI pins of the AVR are not connected to anything disruptive, the AVR chip can stay soldered on a PCB while reprogramming. All that is needed is a 6-pin connector and ...
