M48T59Y-70MH1 datasheet by STMicroelectronics

M48T59Y-70MH1 Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this device?
  The M48T59Y-70MH1 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) pins?
  The POR pin should be connected to VCC through a resistor and capacitor to ensure a clean power-on reset. The VS pin should be connected to a voltage source (e.g., VCC) through a resistor and capacitor to set the voltage threshold for the supervisor function.
• What is the recommended crystal oscillator configuration for this device?
  The M48T59Y-70MH1 requires a 32.768 kHz crystal oscillator with a load capacitance of 6-10 pF and a series resistance of 1-2 kΩ. The crystal should be connected between the X1 and X2 pins.
• How do I program the device's internal memory?
  The M48T59Y-70MH1's internal memory can be programmed using a serial protocol (I2C or SPI) through the SDI and SDO pins. A programming adapter or a dedicated programmer is required to access the memory.
• What is the maximum clock frequency supported by this device?
  The M48T59Y-70MH1 can operate up to 70 MHz, but the maximum clock frequency depends on the specific application and the quality of the crystal oscillator.
