+STM32MP1 is a microprocessor designed by STMicroelectronics +based on Arm Cortex-A7. +It is an Armv7-A platform, using dedicated code from TF-A. +More information can be found on `STM32MP1 Series`_ page. + +For TF-A common configuration of STM32 MPUs, please check +:ref:`STM32 MPUs` page. + +STM32MP1 Versions +----------------- + +There are 2 variants for STM32MP1: STM32MP13 and STM32MP15 + +STM32MP13 Versions +~~~~~~~~~~~~~~~~~~ +The STM32MP13 series is available in 3 different lines which are pin-to-pin compatible: + +- STM32MP131: Single Cortex-A7 core +- STM32MP133: STM32MP131 + 2*CAN, ETH2(GMAC), ADC1 +- STM32MP135: STM32MP133 + DCMIPP, LTDC + +Each line comes with a security option (cryptography & secure boot) and a Cortex-A frequency option: + +- A Cortex-A7 @ 650 MHz +- C
