Product details

Texas Instruments's F28M35M20B1RFPS 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 C28x/ARM® Cortex®-M3 incorporates dedicated cryptographic accelerators that perform AES-256 encryption in just 12 clock cycles with constant-time execution.With 32-Bit Dual-Core secure execution environments, the device maintains complete isolation between trusted and untrusted code execution domains.Operating at 75MHz/75MHz, the microcontroller performs elliptic curve point multiplication in under 1ms, enabling rapid secure session establishment.The CANbus, EBI/EMI, I²C, McBSP, SCI, SPI, SSI, UART/USART interfaces include hardware-enforced protocol filtering that prevents side-channel attacks on communication channels.Integrated Brown-out Detect/Reset, DMA, POR, PWM, WDT feature true random number generators with NIST SP 800-90B compliance for cryptographic key generation.74 protected interfaces include voltage and frequency monitors that detect tampering attempts on physical connections.256KB/256KB 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.72KB of zeroizable memory instantly erases sensitive data when tamper detection triggers, meeting Common Criteria EAL6+ requirements.The 1.2V, 1.8V, 3.3V range includes active voltage tamper detection that triggers immediate memory erasure during glitching attempts.Secure A/D 20x12b incorporate noise injection techniques that prevent power analysis attacks on sensitive cryptographic operations.Rated for -40°C ~ 125°C (TJ), 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 144-TQFP Exposed Pad uses epoxy resin that becomes conductive upon drilling, triggering immediate zeroization of all secure data.Available in 144-HTQFP (20x20), the microcontroller undergoes extensive fault injection testing to verify tamper resistance.
