As we discussed in the past few days, a scalable microcontroller platform can add value in terms of reducing energy, context-aware products and connected systems. Today, we will take a brief look at security. The MSP430 FRAM microcontroller portfolio offers both intrinsic advantages due to FRAM and varying peripherals depending on the security needs of your system.
All MSP430FRx MCUs enable some key security advantages that can provide some code/data security for your system. FRAM does not require a charge pump, is resistant to electric/magnetic fields and can retain state on power failure that offers the following benefits:
- Memory is protected from some types of physical attacks
- FRAM is not susceptible to soft errors
- FRAM can be used to update security keys quickly and send notifications in case of certain state changes
Beyond the basics, peripherals across the microcontroller family vary across price points and memory configurations. For instance, the MSP430FR2033 inside our baseline MSP430FR2x series of the FRAM portfolio provides some basic JTAG and memory lock capabilities. The MSP430FR6972 on the other hand has more features, offering a 256-bit AES encryption engine, a true random number seed and IP encapsulation for locking specific pieces of memory.
