M41ST87WSS6F Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the M41ST87WSS6F?
  The recommended operating voltage range for the M41ST87WSS6F is 2.7V to 5.5V.
• How do I ensure the accuracy of the RTC (Real-Time Clock) in the M41ST87WSS6F?
  To ensure the accuracy of the RTC, it is recommended to use a high-quality crystal oscillator with a frequency of 32.768 kHz, and to calibrate the RTC regularly using an external time reference.
• What is the maximum current consumption of the M41ST87WSS6F?
  The maximum current consumption of the M41ST87WSS6F is 1.5 mA at 5V, and 0.5 mA at 3V.
• How do I interface the M41ST87WSS6F with a microcontroller?
  The M41ST87WSS6F can be interfaced with a microcontroller using a serial interface such as I2C or SPI. The specific interface used will depend on the microcontroller and the application requirements.
• What is the purpose of the VBAT pin on the M41ST87WSS6F?
  The VBAT pin is used to connect a battery that powers the RTC and SRAM when the main power supply is turned off. This allows the RTC and SRAM to retain their data even when the main power supply is off.
