STM32G491VET6 | STMicroelectronics

Flash-Microcontroller, STM32G491VET6, STMicroelectronics

The STM32G491VET6 device is based on the high-performance Arm Cortex-M4 32-bit RISC core. It operates at a frequency of up to 170 MHz. The Cortex-M4 core features a single-precision floating-point unit (FPU), which supports all the Arm single-precision data-processing instructions and all the data types. It also implements a full set of DSP (digital signal processing) instructions and a memory protection unit (MPU) which enhances the application’s security. This device embeds high-speed memory (up to 512 Kbytes of flash memory, and 112 Kbytes of SRAM), a Quad-SPI flash memory interface, an extensive range of enhanced I/O and peripheral connected to two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix. The device also embeds several protection mechanisms for embedded flash memory and SRAM: readout protection, write protection, securable memory area and proprietary code readout protection. The device embeds peripheral allowing mathematical/arithmetic function acceleration (CORDIC for trigonometric function and FMAC unit for filter function).
