Read Data Bytes at Higher Speed (FAST_READ)
The FAST_READ command reads data from the memory array at the frequency (f
input, with a maximum speed of 104 MHz. The host system must first select the device by driving CS# low.
The FAST_READ command is then written to SI, followed by a 3 byte address (A23-A0) and a dummy byte.
Each bit is latched on the rising edge of SCK. The memory array data, at that address, are output serially on
SO at a frequency f
The FAST_READ command sequence is shown in
byte specified can start at any location of the memory array. The device automatically increments to the next
higher address after each byte of data is output. The entire memory array can therefore be read with a single
FAST_READ command. When the highest address is reached, the address counter reverts to 000000h,
allowing the read sequence to continue indefinitely.
The FAST_READ command is terminated by driving CS# high at any time during data output. The device
rejects any FAST_READ command issued while it is executing a program, erase, or Write Registers
operation, and continues the operation uninterrupted.
