MCUs/processors with tamper, asymmetric HW encryption, and hibernation/low power mode features

Hi Jordan,

I am certain there is a solution available for your company in our TI EP portfolio.

1) While a dedicated on-chip tamper detection peripheral is not available, there are plenty of peripherals to support system level anti-temper methods.

(See https://training.ti.com/anti-tamper-techniques-thwart-attacks-smart-meters-introduction-what-meter-tampering-and-why-do)

2) AM263x and AM273x devices include a Hardware Security Module (HSM). The AM243x device includes a Device Management and Security Controller (DMSC). Both HSM and DMSC contain hardware cryptographic subsystems that provide hardware acceleration of symmetric and asymmetric cryptographic operations and is supported by secure device DMA to efficiently process data.

3) While the devices do not have a specifically designated "Low-Power Mode", low power states can be achieved by disabling IP, gating IP clock signals, reducing operating frequencies, and putting device cores into WFI/WFE operating modes.

I would highly recommended reviewing the following Sitara MCU devices and associated Datasheet and TRM documents for more information.
