The STM32L4R5xx, STM32L4R7xx and STM32L4R9xx devices are an ultra-low-power microcontrollers family (STM32L4+ Series) based on the high-performance Arm ® Cortex ® -M4 32-bit RISC core. They operate at a frequency of up to 120 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. The Cortex-M4 core also implements a full set of DSP (digital signal processing) instructions and a memory protection unit (MPU) which enhances the application’s security. These devices embed 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), two OctoSPI Flash memories interface (available on all packages) and an extensive 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 embed several protection mechanisms for embedded Flash memory and SRAM: readout protection, write protection, proprietary code readout protection and a firewall. These devices offer a fast 12-bit ADC (5 Msps), two comparators, two operational amplifiers, two DAC channels, an internal voltage reference buffer, a low-power RTC, two general-purpose 32-bit timer, two 16-bit PWM timers dedicated to motor control, seven general-purpose 16-bit timers, and two 16-bit low-power timers. The devices support four digital filters for external sigma delta modulators (DFSDM). In addition, up to 24 capacitive sensing channels are available. They also feature standard and advanced communication interfaces such as: four I2Cs, three SPIs, three USARTs, two UARTs and one low-power UART, two SAIs, one SDMMC, one CAN, one USB OTG full-speed, one camera interface and one DMA2D controller. The devices operate in the -40 to +85 °C (+105 °C junction) and -40 to +125 °C (+130 °C junction) temperature ranges from a 1.71 to 3.6 V for V DD power supply when using internal LDO regulator and a 1.05 to 1.32 V V DD12 power supply when using external SMPS supply. A comprehensive set of power-saving modes allows the design of low-power applications. Some independent power supplies are supported like an analog independent supply input for ADC, DAC, OPAMPs and comparators, a 3.3 V dedicated supply input for USB and up to 14 I/Os, which can be supplied independently down to 1.08 V. A VBAT input allows to backup the RTC and backup the registers. Dedicated V DD12 power supplies can be used to bypass the internal LDO regulator when connected to an external SMPS. The STM32L4Rxxx family offers six packages from 100-pin to 169-pin.
