Read Data Bytes at Higher Speed
(FAST_READ)
The device is first selected by driving Chip Select
(S) Low. The instruction code for the Read Data
Bytes at Higher Speed (FAST_READ) instruction
is followed by a 3-byte address (A23-A0) and a
dummy byte, each bit being latched-in during the
rising edge of Serial Clock (C). Then the memory
contents, at that address, is shifted out on Serial
Data Output (Q), each bit being shifted out, at a
maximum frequency f
Serial Clock (C).
The instruction sequence is shown in
The first byte addressed can be at any location.
The address is automatically incremented to the
Figure 14. Read Data Bytes at Higher Speed (FAST_READ) Instruction Sequence
and Data-Out Sequence
Note: 1. Address bits A23 to A16 must be set to 00h.

next higher address after each byte of data is shift-
ed out. The whole memory can, therefore, be read
with a single Read Data Bytes at Higher Speed
(FAST_READ) instruction.
There is no address roll-over; when the highest
address (0FFFFh) is reached, the instruction
should be terminated.
The
(FAST_READ) instruction is terminated by driving
Chip Select (S) High. Chip Select (S) can be driv-
en High at any time during data output. Any Read
Data Bytes at Higher Speed (FAST_READ) in-
struction, while an Erase, Program or Write cycle
is in progress, is rejected without having any ef-
fects on the cycle that is in progress.
