2. Description
The AT97SC3203S is a fully integrated security module designed to be integrated into
embedded systems. It implements version 1.2 of the Trusted Computing Group (TCG)
specification for Trusted Platform Modules (TPM).
The TPM includes a cryptographic accelerator capable of computing a 2048-bit RSA
signature in 500 ms and a 1024-bit RSA signature in 100 ms. Performance of the
SHA-1 accelerator is 50 µs per 64-byte block. In most cases, TCG key generation
operations will be completed using a proprietary mechanism in less than 1 msec.

Description (continued)
Communication to and from the TPM occurs through a modified 100-kHz SMBus two-wire interface. The TPM includes a hardware random number generator, including a FIPS-approved
Pseudo Random Number Generator, that is used for key generation and TCG protocol functions. The RNG is also available to the system to generate random numbers that may be needed
during normal operation.
The chip uses a dynamic internal memory management scheme to store multiple RSA keys.
Other than the standard TCG commands (TPM_FlushSpecific, TPM_Loadkey2), no system
intervention is required to manage this internal key cache.
Full documentation for TCG primitives can be found on the TCG Web site located at www.trustedcomputinggroup.org. This specification includes only mechanical, electrical and SMBus
protocol information.

2. Dimension D does not include mold Flash, protrusions or gate burrs. Mold Flash, protrusions and gate burrs shall not exceed
0.15 mm (0.006 in) per side.
3. Dimension E1 does not include inter-lead Flash or protrusions. Inter-lead Flash and protrusions shall not exceed 0.25 mm (0.010 in)
per side.
4. Dimension b does not include Dambar protrusion. Allowable Dambar protrusion shall be 0.08 mm total in excess of the b
dimension at maximum material condition. Dambar cannot be located on the lower radius of the foot. Minimum space between
protrusion and adjacent lead is 0.07 mm.
5. Dimension D and E1 to be determined at Datum Plane H.

tolerances, datums, etc.
2. Dimension b applies to metallized terminal and is measured between 0.15 mm and 0.30 mm from the terminal tip. If the
terminal has the optional radius on the other end of the terminal, the dimension should not be measured in that radius area.
