Introduction
The Atmel® TPM™ Development Kit includes examples of how to use the Trusted Platform Module
(TPM) in an embedded and PC application. Source code is provided to enable an embedded designer to
make quick progress in understanding and utilizing the TPM.
The TPM Development Kits are based on the Atmel SAM4S ARM ® with an added I2C or SPI TPM
device. The TPM demonstration code and evaluation software uded on a USB flash drive which are incl
comes with the kits. The board includes a or ISPI 2C TPM, a SAMS4 processor, a board reset button, a
JTAG connector, and detachable segments to allow for engineering system integration as shown in
Figure 1.
Complete SAM4S ARM documentation can be found on the Atmel web site at the following link:
