STM32L4Q5RGT3 - STMicroelectronics

STM32L4Q5RGT3 Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the STM32L4Q5RGT3?
  The maximum operating frequency of the STM32L4Q5RGT3 is 120 MHz, but it can be overclocked to 140 MHz with a reduced voltage range.
• How do I configure the internal clock source for the STM32L4Q5RGT3?
  The internal clock source can be configured using the RCC (Reset and Clock Control) peripheral. The HSE (High-Speed External) clock, HSI (High-Speed Internal) clock, or MSI (Multi-Speed Internal) clock can be used as the clock source. The clock configuration is done using the RCC_CFGR register.
• What is the maximum amount of RAM and Flash memory available on the STM32L4Q5RGT3?
  The STM32L4Q5RGT3 has 1 MB of Flash memory and 128 KB of SRAM (Static Random Access Memory). Additionally, it has 32 KB of RETRAM (Retention RAM) which is a backup RAM that retains its content even when the device is in low-power modes.
• How do I use the low-power modes of the STM32L4Q5RGT3?
  The STM32L4Q5RGT3 has several low-power modes, including Sleep, Stop, and Standby modes. These modes can be entered using the PWR (Power) peripheral. The device can also wake up from these modes using various wake-up sources such as interrupts, RTC (Real-Time Clock) alarms, or external events.
• What is the purpose of the ART (Adaptive Real-Time) accelerator in the STM32L4Q5RGT3?
  The ART accelerator is a peripheral that accelerates the execution of Flash memory accesses, allowing for faster code execution and improved performance. It is particularly useful for applications that require high-speed data processing and low latency.
