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 fC, during the falling edge of
Serial Clock (C).
The instruction sequence is shown in Figure 15..
The first byte addressed can be at any location.
The address is automatically incremented to the
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. When the highest ad-
dress is reached, the address counter rolls over to
000000h, allowing the read sequence to be contin-
ued indefinitely.
The
Read
Data
Bytes
at
Higher
Speed
(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.
