STMicroelectronics STM32MP253DAI3 32 bit Core Microprocessor STM32MP25xA/D 32 bit ARM V8-A 400 MHz 436-Pin TFBGA

The STMicroelectronics ARM Microcontroller is 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. The Cortex-M33 core features a floating point unit single precision which supports Arm single precision data processing instructions and data types. The Cortex-M33 supports a full set of DSP instructions, TrustZone and a memory protection unit which enhances application security.
