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 5V 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 cummulative hours.
5. Applies to MT28F200B5 only.
6. Applies to MT28F002B5 and MT28F200B5 with BYTE = LOW.
7. Parameter is specified when device is not accessed. Actual current draw will be ICC12 (5V VCC) plus read current if a
READ is executed while the device is in erase suspend mode.
