A25LQ080 Series

(April, 2016, Version 1.0)

AMIC Technology Corp.

Read Data Bytes at Higher Speed by Dual Input and Dual Output (FAST_READ_DUAL_INPUT_OUTPUT)

The FAST_READ_DUAL_INPUT_OUTPUT (BBh) instruction

is similar to the FAST_READ (0Bh) instruction except the

data is input and output on two pins, IO0 and IO1, instead of

just DO. This allows data to be transferred from the

A25LQ080 at twice the rate of standard SPI devices.

Similar

the

FAST_READ

instruction,

the

FAST_READ_DUAL_INPUT_OUTPUT

instruction

can

operate at the highest possible frequency of fC (See AC

Characteristics).
