NOTES:

1.

See AC Input/Output Reference Waveform for timing measurements.

2.

3.

Sampled, but not 100% tested.

4.

See

Test Configuration (Figure 13), 5 V High-Speed Test component values.

5.

Test Configuration (Figure 13), 5 V Standard Test component values.

6.

Dynamic BYTE# switching between word and byte modes is not supported. Mode changes must be made when the device

is in deep power-down or powered down.

As of the publication date of this document, not all 28F200B5 –60 devices meet the 55 ns read specification. Please refer

to the

5 Volt Boot Block Flash Memory Family 28F200B5, 28F004/400B5, 28F800B5 Specification Updateto determine

the specific 28F200B5 –T/B60 material that is capable of 55 ns read access times. All other 28F200B5 T/B60 devices are
