STM32F413VGT6

The STMicroelectronics STM32F413VGT6 is a high-performance ARM Cortex-M4 microcontroller from the STM32F4 series. Running at 100MHz with single-precision FPU and DSP instructions, it delivers 125 DMIPS and 334 EEMBC CoreMark performance. The generous 1.5MB Flash and 320KB SRAM support complex applications and large data buffers. Unique to the STM32F413 is the integrated AES-256 hardware accelerator for secure communication and data protection. The DFSDM peripheral directly interfaces with external sigma-delta modulators for precision current and voltage measurement. Multiple communication interfaces including SAI (Serial Audio Interface) make it suitable for audio processing applications. The 100-pin LQFP package provides up to 82 GPIO pins.

The STM32F413VGT6 operates as a high-performance ARM Cortex-M4 microcontroller: 1) Cortex-M4 Core: The 100MHz CPU executes Thumb-2 instructions with a 3-stage pipeline. The hardware FPU accelerates single-precision floating-point operations, and the DSP instruction set supports saturating arithmetic, MAC, and SIMD operations for signal processing. 2) Memory System: 1.5MB Flash stores program code with prefetch and cache. 320KB SRAM is split across multiple banks for concurrent DMA and CPU access. The QuadSPI interface supports memory-mapped external Flash. 3) AES Accelerator: The hardware AES-256 engine encrypts/decrypts data in ECB, CBC, CTR, and GCM modes without CPU intervention, supporting secure boot and encrypted communication. 4) DFSDM: Four digital filter channels interface directly with external sigma-delta modulators, providing integrated decimation filtering for precision measurement without external ADCs.
