IS25C32B-Automotive

SERIAL INTERFACE DESCRIPTION

MASTER: The device that provides a clock signal.

SLAVE: The IS25C32B is a slave because the clock

signal is an input.

TRANSMITTER/RECEIVER: The IS25C32B has both

data input (SI) and data output (SO).

MSB: The most significant bit. It is always the first bit

transmitted or received.

OP-CODE: The first byte transmitted to the slave fol-

lowing CS transition to LOW. If the OP-CODE is a valid

member of the IS25C32B instruction set (Table 3), then

it is decoded appropriately. If the OP-CODE is not valid,

and the SO pin remains in high impedance.
