M41T93RQA6F Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the M41T93RQA6F is 2.5V to 5.5V.
  • To ensure the accuracy of the RTC clock, it is recommended to use a high-quality crystal oscillator and to follow the recommended crystal load capacitance values. Additionally, the device should be operated within the recommended temperature range and voltage range.
  • Yes, the M41T93RQA6F can be used as a battery-backed SRAM. The device has a built-in battery switch that allows the SRAM to be powered from a battery or a supercapacitor, allowing the data to be retained even when the main power supply is removed.
  • The clock calendar can be programmed using the I2C interface. The device has a set of registers that control the clock and calendar functions, and these registers can be written to using the I2C interface. The datasheet provides a detailed description of the register map and the programming sequence.
  • The maximum frequency of the clock output is 32.768 kHz, which is the typical frequency of a watch crystal oscillator.
