STM32MP133AAE3

Microprocessors Overview

The STM32MP133AAE3 is a 32-bit Arm Cortex-A7 microprocessor operating at up to 1 GHz. It features 32-Kbyte L1 instruction and data caches, plus a 128-Kbyte unified L2 cache. The device includes 168 Kbytes of internal SRAM and supports external DDR memory up to 1 Gbyte via LPDDR2/LPDDR3 or DDR3/DDR3L interfaces. Key peripherals include dual Ethernet MACs with IEEE 1588v2 support, two CAN FD controllers, two USB 2.0 high-speed ports, and two SDMMC interfaces. Security is enhanced by Arm TrustZone, hardware cryptographic accelerators, and tamper detection pins.
