M41T64Q6F datasheet by STMicroelectronics

M41T64Q6F Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the M41T64Q6F?
  The maximum operating frequency of the M41T64Q6F is 1 MHz.
• How do I handle the power-on reset (POR) of the M41T64Q6F?
  The M41T64Q6F has a built-in POR circuit that resets the device when the power supply voltage (VCC) rises above 1.5 V. No external circuitry is required.
• What is the purpose of the VCCB pin on the M41T64Q6F?
  The VCCB pin is a backup power supply input that allows the device to retain its data even when the main power supply (VCC) is turned off. It is typically connected to a battery or a supercapacitor.
• How do I ensure data integrity during power failures with the M41T64Q6F?
  The M41T64Q6F has a built-in power-fail detect circuit that automatically switches to the backup power supply (VCCB) during power failures, ensuring data integrity.
• What is the maximum current consumption of the M41T64Q6F?
  The maximum current consumption of the M41T64Q6F is 2 mA at 1 MHz, and 1 mA in standby mode.
