Shenzhen Meiyuxin Technology Co., Ltd. 【Electronic Distribution List BOM】STM32MP157FAC1 Microprocessor - MPU MPU Arm Dual Cortex-A7 800 MHz, Arm Cortex-M4 Quality Assurance New original! ! !

Product Description:

The STM32MP157FAC1 device is based on a high-performance dual-core Arm® Cortex®-A7 32-bit RISC core running at up to 800 MHz. Cortex-A7 processors have a 32 KB L1 instruction cache per CPU, a 32 KB L1 data cache CPU and 256 KB L2 cache per CPU. The Cortex-A7 processor is an extremely power-efficient application processor designed to provide rich performance for high-end wearable devices, as well as other low-power embedded and consumer applications. It offers up to 20% better single thread performance than Cortex-A5 and offers similar performance to CortexA9.

The STM32MP157FAC1 Cortex-A7 combines all the features of the high-performance Cortex-A15 and CortexA17 processors, including hardware virtualization support, NEON™ and 128-bit AMBA®4AXI bus interface.

The STM32MP157FAC1 device also embeds a Cortex®-M4 32-bit RISC core running at up to 209 MHz. The Cortex-M4 core has a floating point unit (FPU) single precision that supports Arm® single precision data processing instructions and data types. The Cortex®-M4 supports a full set of DSP instructions and a memory protection unit (MPU) which enhances application security.

The STM32MP157FAC1 device provides an external SDRAM interface supporting external memory up to 8 Gbit density (1 Gbyte), 16 or 32 bit LPDDR2/LPDDR3 or DDR3/DDR3L up to 533 MHz. The STM32MP157FAC1 device integrates high-speed embedded memory, 708 KB of internal SRAM (including 256 KB of AXI SYSRAM, three banks of 128 KB each AHB SRAM, 64 KB of AHB SRAM in the backup domain and 4 KB of SRAM in the backup domain), As well as a wide range of enhanced I/O and peripherals connected to the APB bus, AHB bus, a 32-bit multi-AHB bus matrix and a 64-bit multilayer AXI interconnect supporting internal and external memory access.

All STM32MP157FAC1 devices provide two ADCs, two DACs, a low-power RTC, 12 general-purpose 16-bit timers, two PWM timers for motor control, five low-power timers, a true random Number Generator (RNG). These devices support six digital filters (DFSDM) for the external sigma delta modulator. They also have standard and advanced communication interfaces.
