Atmel Crypto Products Portfolio
Atmel CryptoController (TPM)
Atmel CryptoController is a complete turnkey Trusted Platform
Module(TPM) solution providing ultra-strong security for both
PC and embedded systems. Primary TPM capabilities include
IP protection, system integrity, authentication, and secure
communication. The core building blocks in CryptoController
are the Atmel AVR microcontrollers and our expertise in silicon
security technologies. Additional security measures include a
variety of tamper-evident circuits such as voltage, temperature
and frequency tampers. Available in 28-TSSOP and space saving
40-lead QFN (MLF) packages, CryptoController provides a
standards-based solution for all computing devices.
