M41T82SM6E datasheet by STMicroelectronics

M41T82SM6E Frequently Asked Questions (FAQs)

• What is the recommended layout and routing for the crystal oscillator circuit?
  STMicroelectronics provides a recommended layout and routing guide for the crystal oscillator circuit in their application note AN1011. It's essential to follow these guidelines to ensure proper oscillator operation and minimize noise and interference.
• How do I handle the power-on reset (POR) and voltage supervisor (VS) pins?
  The POR and VS pins require external resistors and capacitors to set the reset threshold and timeout period. Refer to the datasheet and application notes for specific component values and configuration guidelines.
• What is the maximum allowed frequency deviation for the crystal oscillator?
  The M41T82SM6E can tolerate a maximum frequency deviation of ±100 ppm for the crystal oscillator. Exceeding this limit may affect the device's accuracy and reliability.
• Can I use the M41T82SM6E with a battery voltage below 1.5V?
  No, the M41T82SM6E is not designed to operate with a battery voltage below 1.5V. The device's minimum operating voltage is 1.5V, and operating below this voltage may cause malfunction or damage.
• How do I ensure the accuracy and stability of the real-time clock (RTC) module?
  To ensure accuracy and stability of the RTC module, it's essential to use a high-quality crystal oscillator, follow proper layout and routing guidelines, and minimize noise and interference on the VCC and GND pins.
