STM32WLE4JCI6 - STMicroelectronics

STM32WLE4JCI6 Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the STM32WLE4JCI6?
  The maximum operating temperature range for the STM32WLE4JCI6 is -40°C to 85°C, but it can be extended to 105°C with some limitations on the clock frequency and supply voltage.
• How do I configure the internal oscillator to achieve the highest accuracy?
  To achieve the highest accuracy, you need to trim the internal oscillator using the HSITRIM register. You can do this by following the calibration procedure described in the STM32WLE4JCI6 datasheet, section 5.3.7.
• What is the maximum current consumption of the STM32WLE4JCI6 in low-power modes?
  The maximum current consumption of the STM32WLE4JCI6 in low-power modes depends on the specific mode and the peripherals enabled. In Stop mode, the current consumption can be as low as 2.5 μA, while in Standby mode, it can be as low as 1.5 μA. Refer to the datasheet, section 5.2, for more information.
• How do I use the internal flash memory to store data?
  The internal flash memory of the STM32WLE4JCI6 can be used to store data using the Flash Interface (FI) module. You need to use the HAL_FLASH module in the STM32CubeWLE firmware package to read and write data to the flash memory. Refer to the STM32CubeWLE firmware package documentation for more information.
• What is the maximum frequency of the SPI interface?
  The maximum frequency of the SPI interface on the STM32WLE4JCI6 is 50 MHz, but it can be limited by the clock frequency of the peripheral and the external components used.
