Product details
Atmel's AT80C51RA2-RLTUM delivers military-grade security in Embedded - Microcontrollers, designed for cryptographic applications and secure authentication systems. Its tamper-resistant architecture makes it ideal for hardware security modules and payment terminals.The 80C51 incorporates dedicated cryptographic accelerators that perform AES-256 encryption in just 12 clock cycles with constant-time execution.With 8-Bit secure execution environments, the device maintains complete isolation between trusted and untrusted code execution domains.Operating at 40/20MHz, the microcontroller performs elliptic curve point multiplication in under 1ms, enabling rapid secure session establishment.The UART/USART interfaces include hardware-enforced protocol filtering that prevents side-channel attacks on communication channels.Integrated POR, PWM, WDT feature true random number generators with NIST SP 800-90B compliance for cryptographic key generation.32 protected interfaces include voltage and frequency monitors that detect tampering attempts on physical connections.The ROMless implementation uses one-time-programmable sectors for secure boot code that cannot be modified after deployment.512 x 8 of zeroizable memory instantly erases sensitive data when tamper detection triggers, meeting Common Criteria EAL6+ requirements.The 4.5V ~ 5.5V range includes active voltage tamper detection that triggers immediate memory erasure during glitching attempts.The Internal includes frequency drift detection that identifies clock glitching attempts with 100ns resolution.Rated for -40°C ~ 85°C (TA), the device maintains security features even under extreme environmental stress testing.Surface Mount packaging incorporates mesh shields that detect physical intrusion attempts with 10 m resolution.The 44-LQFP uses epoxy resin that becomes conductive upon drilling, triggering immediate zeroization of all secure data.Available in 44-VQFP (10x10), the microcontroller undergoes extensive fault injection testing to verify tamper resistance.
