STM32L4R7VIT6 Product Details

STM32L4R7VIT6 Description


An ultra-low-power microcontroller family (STM32L4+ Series) based on the powerful Arm? Cortex?-M4 32-bit RISC processor is the STM32L4R7VIT6 chip. They run at up to 120 MHz of frequency.

All of the Arm? single-precision data-processing instructions and all data types are supported by the Cortex-M4 core's single-precision floating-point unit (FPU). A memory protection unit (MPU) and a full set of DSP (digital signal processing) instructions are also implemented by the CortexM4 core, which increases the security of the program.

These chips include two OctoSPI Flash memory interfaces, a flexible external memory controller (FSMC) for static memories, two high-speed memories (2 Mbytes of Flash memory and 640 Kbytes of SRAM), a flexible external memory controller (FSMC) for static memories (for devices with packages of 100 pins and more), and a wide range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses, and a 32-bit multi-AHB bus matrix.

The STM32L4Rxxx devices have a firewall, readout protection, write protection, proprietary code readout protection, and other protection methods for embedded Flash memory and SRAM.

Fast 12-bit ADC (5 Msps), two comparators, two operational amplifiers, two DAC channels, internal voltage reference buffer, low-power RTC, two general-purpose 32-bit timers, two 16-bit PWM timers for motor control, seven general-purpose 16-bit timers, and two 16-bit low-power timers are all features of these devices. Four digital filters for external sigma delta modulators are supported by the devices (DFSDM). Furthermore, there are up to 24 capacitive sensing channels available.
