NOTE: 1. WRITE operations are tested at VCC/VPP voltages equal to or less than the previous ERASE, and READ operations are
tested at VCC voltages equal to or less than the previous WRITE.
2. Absolute WRITE/ERASE protection when VPP ≤ VPPLK.
3. When 3.3V VCC and VPP are used, Vcc cannot exceed VPP by more than 500mV during WRITE and ERASE operations.
4. For SmartVoltage-compatible production programming, 12V VPP is supported for a maximum of 100 cycles and may
be connected for up to 100 cumulative hours.
5. Applies to MT28F200B3 only.
6. Applies to MT28F002B3 and MT28F200B3 with BYTE = LOW.
7. Parameter is specified when device is not accessed. Actual current draw will be ICC10 plus read current if a READ is
executed while the device is in erase suspend mode.
