Product details
STMicroelectronics's STM32H7A3AII6Q 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 ARM® Cortex®-M7 incorporates dedicated cryptographic accelerators that perform AES-256 encryption in just 12 clock cycles with constant-time execution.With 32-Bit Single-Core secure execution environments, the device maintains complete isolation between trusted and untrusted code execution domains.Operating at 280MHz, the microcontroller performs elliptic curve point multiplication in under 1ms, enabling rapid secure session establishment.The CANbus, EBI/EMI, HDMI-CEC, I²C, IrDA, LINbus, MDIO, MMC/SD/SDIO, SAI, SPDIF, SPI, SWPMI, UART/USART, USB OTG interfaces include hardware-enforced protocol filtering that prevents side-channel attacks on communication channels.Integrated Brown-out Detect/Reset, DMA, I²S, LCD, POR, PWM, WDT feature true random number generators with NIST SP 800-90B compliance for cryptographic key generation.121 protected interfaces include voltage and frequency monitors that detect tampering attempts on physical connections.2MB (2M x 8) secure storage accommodates FIPS 140-2 Level 3 compliant firmware with integrity protection and anti-rollback features.The FLASH implementation uses one-time-programmable sectors for secure boot code that cannot be modified after deployment.1.4M x 8 of zeroizable memory instantly erases sensitive data when tamper detection triggers, meeting Common Criteria EAL6+ requirements.The 1.62V ~ 3.6V range includes active voltage tamper detection that triggers immediate memory erasure during glitching attempts.Secure A/D 24x16b; D/A 3x12b incorporate noise injection techniques that prevent power analysis attacks on sensitive cryptographic operations.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 169-UFBGA uses epoxy resin that becomes conductive upon drilling, triggering immediate zeroization of all secure data.Available in 169-UFBGA (7x7), the microcontroller undergoes extensive fault injection testing to verify tamper resistance.
