Optimized for mixed-signal applications Cortex-M0+ Radio co-processor 2 Main concerns for embedded design � Security � Increase the robustness against attacks � Low power consumption � Long life time, small battery size � Integration, performance, ecosystem � Best fit versus the application requirements 3 First STM32 based on Cortex-M33 STM32L5 is the answer � More security with TrustZone and ST security implementation � HW to increase resistance to logical and board level attack � Lower Power consumption � STM32 ultra-low-power technology � Integration, performance, ecosystem � More performance, choice of packages and wide ecosystem 4 Security: TrustZone for isolation ST implementation provides a high granularity of isolation STM32L5 Un-Trusted Trusted Un-Trusted Application Trusted Application � Each GPIO or peripheral, DMA channel, clock configuration register, ART or small part of Flash memory or SRAM can be configured as Trusted or un-Trusted � Full isolation of trusted and non-trusted worlds 5 Security: TrustZone for isolation TrustZone provides full isolation Example of IoT application implementation STM32L5 Un-Trusted Trusted Un-Trusted Application Trusted Application RF Sensors 6 Privileged Security: TrustZone and privileged zones STM32L5 Un-Trusted Trusted Un-Trusted & Privileged Trusted & Privileged Un-Trusted & Un-Privileged Trusted & Un-Privileged � More partitioning � Possibility to separate the trusted and un-trusted area with privileged and un-privileged zone � Strong granularity to define each part of memory or each peripheral, DMA channel as privileged or un-privileged Un-Privileged 7 TrustZone: example STM32L5 Un-Trusted Trusted Un-Trusted & Privileged Trusted & Privileged RTOS Secured Keys Secured Boot Privileged Un-Privileged Un-Trusted & Un-Privileged Trusted & Un-Privileged Secured data RF RF Stack Sensor IP Sensors 8 Encryption Decryption Authentication � AES-128/256 Encryption � SHA-256 Authentication � Public Key Acceleration (PKA): for RSA, Diffie-Hellmann or ECC (Elliptic Curve Cryptography) � Certified Crypto library � True Random Number Generator � Unique ID � OTP Zone STM32L5 A full set of security Memory & IP Protection � Active and static Anti-tamper detection � Memory Protection Unit (MPU) � Secure Boot � Read and Write Protection � HDP (Hide Protect) � Unique Boot Entry � OTFDEC (On-the-fly decryption) on Octo SPI to protect external memory � JTAG fuse � TrustZone � SFI (Secure Firmware Installation) 9 Extends battery lifetime � STM32L5 reuses the STM32L4/L4+ technology achieving best-in-class power consumption � STM32L5 integrates an optional SMPS (DC/DC buck voltage regulator) which can be enabled/disabled on the fly to avoid external noise for external RF or data acquisition. � Proven by EEMBC test results: 370 ULPMark-CP 54 ULPMark-PP 10 Ultra-low-power modes Best power consumption numbers with full flexibility Wake-up time VBAT 250 �s Shutdown 3 nA / 187 nA*
