STMicroelectronics STM32MP231DAJ3, Arm Cortex A35, Arm Cortex M33 Microprocessor STM32 16bit 400MHz 361-Pin TFBGA361

The STMicroelectronics MPU with Arm Cortex-A35 devices are based on the high-performance single or dual-core Arm Cortex-A35 64-bit RISC core operating at up to 1.5 GHz. The Cortex‑A35 processor includes a 32-Kbyte L1 instruction cache for each CPU, a 32-Kbyte L1 data cache for each CPU, and a 512-Kbyte L2 cache. The Cortex‑A35 processor uses a highly efficient 8 stage in-order pipeline that has been extensively optimized to provide full Armv8-A features while maximizing area and power efficiency.
