M48T58Y-70MH1E - STMicroelectronics

M48T58Y-70MH1E Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this device?
  The M48T58Y-70MH1E 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. The VS function monitors the VCC supply voltage and keeps the device in reset until VCC reaches a minimum threshold (around 1.5V).
• What is the recommended clock frequency for this device?
  The M48T58Y-70MH1E 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-down or brownout conditions?
  The device has a built-in power-down detection circuit that automatically switches to battery power when the VCC supply voltage falls below a certain threshold. Additionally, the device has a write-protect feature that prevents data corruption during power-down or brownout conditions.
• What is the typical current consumption of this device?
  The typical current consumption of the M48T58Y-70MH1E is around 1.5 mA during active mode and less than 1 μA during standby mode.
