M48Z128-70PM1 datasheet by STMicroelectronics

M48Z128-70PM1 Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the M48Z128-70PM1?
  The maximum operating temperature range for the M48Z128-70PM1 is -40°C to +85°C.
• How do I handle the power-on reset (POR) for the M48Z128-70PM1?
  The M48Z128-70PM1 has an internal POR circuit that resets the device when the power supply voltage (VCC) rises above 1.5V. No external POR circuit is required.
• What is the recommended clock frequency for the M48Z128-70PM1?
  The recommended clock frequency for the M48Z128-70PM1 is up to 1 MHz, but it can operate up to 2 MHz with some limitations.
• How do I ensure data retention in the M48Z128-70PM1 during power-down?
  To ensure data retention, the VCC pin must be maintained above 1.5V during power-down. If VCC falls below 1.5V, the device will enter a low-power state, and data may be lost.
• Can I use the M48Z128-70PM1 in a battery-backed RAM (BBR) application?
  Yes, the M48Z128-70PM1 is suitable for BBR applications. It has a low standby current and can retain data for up to 10 years with a 3V lithium battery.
