M27C256B-10B6 Frequently Asked Questions (FAQs)

• What is the maximum number of erase cycles for the M27C256B-10B6?
  The M27C256B-10B6 can withstand up to 100 erase cycles.
• How do I handle the M27C256B-10B6's power-on reset?
  The M27C256B-10B6 has an internal power-on reset circuit that holds the chip in a reset state until VCC reaches a minimum of 3.5V. No external reset circuitry is required.
• What is the recommended programming voltage for the M27C256B-10B6?
  The recommended programming voltage for the M27C256B-10B6 is 12.75V ± 0.25V.
• Can I use the M27C256B-10B6 in a 5V system?
  Yes, the M27C256B-10B6 can operate in a 5V system, but the programming voltage must be reduced to 5V ± 10%.
• How do I protect the M27C256B-10B6 from over-erasure?
  To prevent over-erasure, ensure that the erase pulse width does not exceed 50ms, and the erase voltage does not exceed 24.5V.
