AC CHARACTERISTICS

Note: Figure assumes 6 wait states for initial access and synchronous read. The Set Configuration Register command sequence

has been written with A18=0; device will output RDY with valid data.

Standard Handshake Burst Suspend at Address 3Fh (Starting Address 3Dh or Earlier)

Note: Figure assumes 6 wait states for initial access and synchronous read. The Set Configuration Register command sequence

has been written with A18=0; device will output RDY with valid data.

1) Address is 3Eh or offset by a multiple of 64 (40h).

2) Address is 3Fh or offset by a multiple of 64 (40h).
