STM32L475RCT6 Description
The STM32L475RCT6 are ultra-low-power microcontrollers built on the powerful 32-bit RISC ARM? Cortex?-M4 core that operates at up to 80 MHz. A floating point unit (FPU) single precision is a characteristic of the Cortex-M4 core that supports all ARM single-precision data-processing instructions and data formats. Additionally, it incorporates a memory protection unit (MPU) that improves program security together with the whole range of DSP instructions. The STM32L475RCT6 includes a wide array of enhanced I/Os and peripherals connected to two APB buses, two AHB buses, and a 32-bit multi-AHB bus matrix. They also include high-speed memories (Flash memory up to 1 Mbyte, up to 128 Kbyte of SRAM), a flexible external memory controller (FSMC) for static memories (for devices with packages of 100 pins and more), a Quad SPI flash memories interface (available on all packages), The STM32L475RCT6 incorporate readout protection, write protection, proprietary code readout protection, firewall, and various more protection methods for embedded Flash memory and SRAM. Two comparators, two operational amplifiers, two DAC channels, an internal voltage reference buffer, a 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 among the features available on the devices. Four digital filters for external sigma delta modulators are supported by the devices (DFSDM).
