Overview
The STM32L4R5ZIT6P, produced by STMicroelectronics, is part of the STM32L4+ Series of ultra-low-power microcontrollers. This device is based on the high-performance Arm® Cortex®-M4 32-bit RISC core, which includes a single-precision floating-point unit (FPU) and supports all Arm® single-precision data-processing instructions and DSP instructions. The microcontroller operates at a frequency of up to 120 MHz and features an adaptive real-time accelerator (ART Accelerator) for 0-wait-state execution from Flash memory.
The STM32L4R5ZIT6P is designed for low-power applications, offering various power-saving modes such as Shutdown, Standby, and Stop modes, with ultra-low power consumption down to 33 nA in Shutdown mode and 2.8 μA in Stop 2 mode with RTC. It also supports a wide temperature range from -40 °C to 85/125 °C.
