M48T08Y-10MH1E datasheet by STMicroelectronics

M48T08Y-10MH1E Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this device?
  The M48T08Y-10MH1E can operate from -40°C to +85°C, but it's recommended to use it within the -20°C to +70°C range for optimal performance.
• How do I handle the power-on reset (POR) and voltage supervisor (VS) functions?
  The POR and VS functions are internally connected and ensure that the device is in a reset state during power-up. No external components are required, but you can use an external capacitor to adjust the POR timing if needed.
• What is the recommended clock frequency for this device?
  The M48T08Y-10MH1E can operate with a clock frequency up to 1 MHz, but it's recommended to use a frequency between 32 kHz and 100 kHz for optimal performance and power consumption.
• How do I ensure data integrity and prevent data corruption during power failures?
  The M48T08Y-10MH1E has a built-in battery switch-over circuit that automatically switches to the internal battery during power failures. Additionally, you can use the device's internal power-fail flag to detect power failures and take necessary actions to prevent data corruption.
• What is the typical current consumption of this device?
  The typical current consumption of the M48T08Y-10MH1E is around 1.5 μA in standby mode and 2.5 mA in active mode, but this can vary depending on the clock frequency, operating voltage, and other factors.
