Security; External Memory - Arduino Portenta C33 Product Reference Manual

2.5 Security

Component Details
Secure boot process that verifies the authenticity and integrity of the firmware before it is loaded
into the device
Built-in hardware cryptography engine that can perform various encryption and decryption
functions, including AES, RSA, and ECC
Secure storage for sensitive data, such as private keys, credentials, and certificates. This storage is
protected by strong encryption and can only be accessed by authorized parties
NXP
Secure communication protocols support, such as TLS, which helps to protect data in transit from
SE050C2
unauthorized access or interception
Tamper detection features that can detect if the device has been physically tampered with. This
helps to prevent attacks such as probing or power analysis attacks that attempt to access the
device's sensitive data
Common Criteria security standard certification, which is an internationally recognized standard
for evaluating the security of IT products

2.6 External Memory

Component Details
NOR flash memory that can be used for storing program code, data, and configuration settings
SPI and QSPI interfaces support, which provide high-speed data transfer rates of up to 104 MHz
Onboard power management features, such as a deep power-down mode and standby mode,
that help to reduce power consumption in battery-powered devices
Hardware-based security features, such as a one-time programmable (OTP) area, a hardware
write-protect pin, and a secure silicon ID
MX25L12833F
Auto-negotiation support, which allows it to automatically detect and configure the link speed
and duplex mode, making it easy to use in a variety of applications
Reliability-enhancing features, such as ECC (Error Correction Code) and a high endurance of up
to 100,000 program/erase cycles
Designed to operate over a wide temperature range, from -40°C to 105°C, making it suitable for
use in harsh industrial and automotive environments
