ARM®Cortex®-M4F Mikrocontroller, 32-bit, 2-3,6V, 512KB, LQFP-100

Beschreibung
Die STM32G474xx basieren auf dem leistungsstarken Arm® Cortex®-M4 32-Bit-RISC-Kern.
Der Cortex-M4-Kern verfügt über eine Single-Precision-FPU, die die Single-Precision-Datenverarbeitungsanweisungen des Arms und alle Datentypen unterstützt. Implementiert ist ein vollständiger Satz von DSP Anweisungen und eine MPU.
Integrierte Hochgeschwindigkeitsspeicher (512 KByte Flash und 128 KByte SRAM), FSMC, Quad SPI Flash Speicherschnittstelle + Peripheriegeräten, die an 2 APB-Busse, 2 AHB-Busse und 1x 32-Bit-Multi-AHB-Busmatrix angeschlossen sind.
Integrierte Schutzmechanismen für eingebettete Flash-Speicher + SRAM.
Die Vorrichtungen beinhalten Peripheriegeräte, die eine mathematische/arithmetische Funktionsbeschleunigung ermöglichen.
