OPTIGA™ TPM
SLB 9673 TPM2.0
Overview
1
Overview
The OPTIGA™ TPM SLB 9673 is a Trusted Platform Module. It is available in PG-UQFN-32-1,-2 package. It supports
an I2C interface with a transfer rate of up to 1 MHz. The OPTIGA™ TPM SLB 9673 is a TPM based on TCG family 2.0
specifications (see [1] and [2]).
This TPM product is targeted to be certified, using the Common Criteria for Information Technology Security
Evaluation (CC), Version 3.1 Rev.5, in the level EAL4+, AVA_VAN.4 (moderate), ALC_FLR.1 according to the
Protection Profile PC Client Specific TPM, TPM Library Specification Family "2.0" Level 0 Revision 1.59
(CERTIFICATE <tbd>1)).
1.1
Power management
In the OPTIGA™ TPM SLB 9673, power management is handled internally; no explicit power-down or standby
mode is available. The device automatically enters a low-power state after each successful command/response
transaction. If a transaction is started on the I2C bus from the host platform, the device will wake immediately
and will return to the low-power mode after the transaction has been finished.
1.2
Device address
The I2C interface uses 7-bit addressing. The default address of the device is 0x2E (also see [2]).

4.1
TPM register polling
Processing of accesses to registers creates a load on the TPM.
If registers are polled in quick succession, the time until the TPM reaches the target state is increased, which
decreases performance and may even lead to violation of maximum timeout values.
To prevent this, a minimum delay between register read accesses must be respected when polling:
•
•
Minimum delay between TPM register reads for polling of TPM_STS_x during command execution: 1 ms
Minimum delay between TPM register reads for polling of TPM_STS_x after device reset before
commandReady set: 1 ms
•
Minimum delay between TPM register reads for all other TPM register polling, including
TPM_STS_x.commandReady set between command, TPM_STS_x.valid and TPM_STS_x.burstCount: 100 µs

I2C Interface Characteristics
The electrical characteristics are compliant to the NXP I2C bus specification [1] for “standard-mode”
(fSCL ≤ 100 kHz), “fast-mode” (fSCL ≤ 400 kHz) and “fast-mode plus” (fSCL ≤ 1000 kHz), with certain deviations
stated in Table 14, Table 15, and Table 16 below.
For printed circuit board design the reduced output fall time tOF compared to the NXP I2C bus specification needs
to be considered!
TA = 25°C, VDD = 3.3V ± 0.3V or VDD = 1.8V ± 0.15V unless otherwise noted.
