STMicro introduces cost-optimized STM32MP13 Cortex-A7 microprocessor

STMicroelectronics’ STM32MP13 1 GHz single-core Arm Cortex-A7 microprocessor series is the latest addition to the Linux-capable STM32MP1 family, with a cost-optimized design that does without the Cortex-M4 real-time core found in the original STM32MP15 series, while still offering Ethernet, CAN FD, camera and display depending on the specific SKU: STM32MP131, STTM32MP133, or STM32MP135. STM32MP131 The STM32MP131 is a single-core Cortex-A7 core clocked at 650 MHz or 1GHz with Ethernet connectivity and is the most cost-effective part of the new STM32MP13 series. Four parts are available in three different packet sizes (TGBGA 289, TFBGA 320, and LFBGA 289) as well as some parts with “advanced security features” that include a cryptographic accelerator, memory protections, code isolation mechanisms for runtime protection, functions to ensure platform authentication, and a complete security ecosystem. The STM32MP131 can run entry-level Linux, bare metal or RTOS systems with Microsoft Azure RTOS pre-integrated. STM32MP133 The STM32MP133 single-core Cortex-A7 […]
