ARM® Cortex®-M33 RT-600 Microcontroller IC 32-Bit Dual-Core 300MHz External Program Memory 176-VFBGA (9x9) The RT600 is a family of dual-core microcontrollers for embedded applications featuring an Arm Cortex-M33 CPU combined with a Cadence Xtensa HiFi4 advanced Audio Digital Signal Processor CPU. The Cortex-M33 includes two hardware coprocessors providing enhanced performance for an array of complex algorithms. The family offers a rich set of peripherals and very low power consumption. The Arm Cortex-M33 is a next generation core based on the ARMv8-M architecture that offers system enhancements, such as ARM TrustZone® security, single-cycle digital signal processing, and a tightly-coupled coprocessor interface, combined with low power consumption, enhanced debug features, and a high level of support block integration. The ARM Cortex-M33 CPU employs a 3-stage instruction pipe and includes an internal prefetch unit that supports speculative branching. A hardware floating-point processor is integrated into the core. On the RT600, the Cortex-M33 is augmented with two hardware coprocessors providing accelerated support for additional DSP algorithms and cryptography. The Cadence Xtensa HiFi 4 Audio DSP engine is a highly optimized audio processor designed especially for efficient execution of audio and voice codecs and pre- and post-processing modules. It supports four 32x32-bit MACs, some support for 72-bit accumulators, limited ability to support eight 32x16-bit MACs, and the ability to issue two 64-bit loads per cycle. There is a floating point unit providing up to four single-precision IEEE floating point MACs per cycle. The RT600 provides up to 4.5 MB of on-chip SRAM (plus an additional 128 KB of tightly-coupled HiFi4 ram) and several high-bandwidth interfaces to access off-chip flash. The FlexSPI flash interface supports two channels and includes an 32 KB cache and an on-the-fly decryption engine. The RT600 is designed to allow the CortexM33 to operate at frequencies of up to 300 MHz and the HiFi4 DSP to operate at frequencies of up to 600 MHz.
