STM32MP151AAC3 MPU IC STM32MP1 1 Core 32-Bit 209MHz 650MHz
The STM32MP151AAC3 is a high-performance heterogeneous multi-core microprocessor unit (MPU) from STMicroelectronics, integrating a 650 MHz Arm Cortex-A7 core with NEON and TrustZone support and a 209 MHz Arm Cortex-M4 core with FPU and MPU for real-time processing, housed in a compact 361-pin TFBGA (12×12 mm) package. It features 708 KB of internal SRAM and supports up to 1 GB of external DDR3/DDR3L/LPDDR2/LPDDR3 memory via a dedicated memory controller, operating from 1.71 V to 3.6 V across an industrial temperature range of -40°C to +125°C. This MPU combines open-source Linux OS capability with real-time MCU determinism, making it ideal for industrial HMI, smart gateways, embedded vision, and IoT edge devices requiring high performance, security, and low-power operation.
It integrates a dual-core architecture: a Cortex-A7 core with 32 KB L1 instruction cache, 32 KB L1 data cache, and 256 KB L2 cache for high-level OS and application tasks, and a Cortex-M4 core with FPU for deterministic real-time control. The device provides 708 KB of internal SRAM and a flexible external memory interface supporting 16/32-bit DDR and LPDDR memories up to 533 MHz. It includes a 24-bit TFT LCD controller, 35 communication interfaces (including Gigabit Ethernet, USB 2.0 OTG, CAN, 6 SPIs, 6 I2Cs, and 8 UARTs), 25 timers, two 12-bit ADCs, and a true random number generator (RNG). Security features comprise TrustZone, secure boot, and cryptographic accelerators, while low-power modes reduce standby current to 2 μA, enabling energy-efficient designs.
