Arm Cortex-M52 is a new microcontroller core featuring Arm Helium technology and designed to bring AI capabilities to smaller and lower-cost IoT devices than what is already possible with SoCs based on the Arm Cortex-M55 core. Arm Cortex-M52 key features and specifications: Architecture – Armv8.1-M Bus interfaces AMBA 5 AXI 32-bit or AMBA 5 AHB 32-bit Main system bus AMBA 5 AHB 32-bit Peripheral bus AMBA 5 AHB 32-bit TCM Access bus (subordinate port) Pipeline – 4-stage pipeline Security Arm TrustZone technology (optional), with optional Security Attribution Unit (SAU) of up to 8 regions. Stack limit checking. Optional support for PACBTI extension (Pointer Authentication, Branch Target Identification) Memory Protection – Optional Memory Protection Units (MPU) for process isolation with up to 16 MPU regions and a background region – if TrustZone is implemented, there can be a Secure and a Non-secure MPUs. DSP extension – 32-bit DSP/SIMD extension Optional single-beat […]
