STMicroelectronics’ STM32MP21 microprocessor family combines a 1.5 GHz 64-bit Arm Cortex-A35 application core with a 300 MHz 32-bit Arm Cortex-M33 core for real-time processing. It is designed for “cost-aware” edge applications in smart factories, smart homes, and smart cities. The new STM32MP21 is a cost-optimized version of the earlier STM32MP23 and STM32MP25 that does without an AI accelerator (yes, those still exist!), GPU, H.264 decoder and encoder, or PCIe Gen2 / USB 3.0 interfaces. It still offers a MIPI CSI-2 camera interface, two Gigabit Ethernet interfaces with Time-Sensitive Networking (TSN), and strong security targeting SESIP Level 3 and PCI pre-certification. STM32MP21 specifications: CPU – Arm Cortex-A35 core running at up to 1.2 or 1.5 GHz with 128KB L2 cache Real-time MCU – Arm Cortex-M33 core with FPU/MPU running at up to 300 MHz GPU – None VPU – None AI accelerator – None Memory 456 KB SRAM 256KB AXI SYSRAM […]
