描述 Description

The i.MX RT600 is a crossover MCU family optimized for 32-bit immersive audio playback and voice userinterface applications combining a high-performance Cadence® Tensilica® HiFi 4 audio DSP corewith a next-generation Cortex-M33 core. The i.MX RT600 family of crossover MCUs is designed to unlock the potentialof voice-assisted end nodes with a secure, power-optimized embedded processor.
The i.MX RT600 family provides up to 4.5MB of on-chip SRAM and several high-bandwidth interfaces to access off-chipflash, including an Octal/Quad SPI interface with an on-the-fly decryption engine. In addition, the family offers arich set of peripherals, EdgeLock 400A security* and extremely low-power consumption with reduced power modesand fast wake-up times.
*A device that incorporates EdgeLock 400A security supports several on-chip security capabilities and is built on afoundation of secure boot, secure debug, and secure life cycle management designed to resist remote and localsoftware attacks.
