M27C801-100B1 datasheet by STMicroelectronics

M27C801-100B1 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the M27C801-100B1?
  The recommended operating voltage range for the M27C801-100B1 is 4.75V to 5.25V.
• How do I handle the power-up and power-down sequences for the M27C801-100B1?
  The power-up sequence should be VCC first, then VPP, and the power-down sequence should be VPP first, then VCC. This ensures that the device is properly initialized and avoids any potential latch-up conditions.
• What is the maximum allowed current for the M27C801-100B1?
  The maximum allowed current for the M27C801-100B1 is 30mA for VCC and 20mA for VPP.
• How do I ensure data retention during power-down or battery removal?
  To ensure data retention during power-down or battery removal, the VCC and VPP pins should be tied to a capacitor to maintain the internal voltage levels, and the CE and OE pins should be tied to VCC to prevent any unwanted writes.
• What is the recommended erase and programming procedure for the M27C801-100B1?
  The recommended erase and programming procedure for the M27C801-100B1 involves applying the appropriate voltage levels to the VPP and VCC pins, and then using the CE and OE pins to control the erase and programming cycles.
