PIN DESCRIPTIONS  
Chip Select (CS): The CS pin activates the device.  
Upon power-up, CS should follow Vcc. When the device  
is to be enabled for instruction input, the signal requires  
a High-to-Low transition. While CS is stable Low, the  
master and slave will communicate via SCK, SI, and SO  
signals. Upon completion of communication, CS must  
be driven High. At this moment, the slave device may  
start its internal write cycle. When CS is high, the  
device enters a power-saving standby mode, unless an  
internal write operation is underway. During this mode,  
the SO pin becomes high impedance.

Suspends Serial Input  
Write Protect (WP): The purpose of this input signal is  
to initiate Hardware Write Protection mode. This mode  
prevents the Block Protection bits and the WPEN bit in  
the Status Register from being altered. To cause  
Hardware Write Protection, WP must be Low at the same  
time WPEN is 1. WP may be hardwired to Vcc or GND.  
PIN DESCRIPTIONS  
Serial Clock (SCK): This timing signal provides syn-  
chronizationbetweenthemicrocontrollerandIS25C128/  
256. Op-Codes, byte addresses, and data are latched  
on SI with a rising edge of the SCK. Data on SO is  
refreshed on the falling edge of SCK for SPI modes (0,0)  
and(1,1).  
HOLD (HOLD): This input signal is used to suspend the  
device in the middle of a serial sequence and temporarily  
ignore further communication on the bus (SI, SO, SCK).  
Together with Chip Select, the HOLD signal allows  
Serial Data Input (SI): This is the input pin for all data  
multiple slaves to share the bus. The HOLD signal  
transitions must occur only when SCK is Low, and be  
held stable during SCK transitions. (See Figure 8 for  
Hold timing) To disable this feature, HOLD may be  
that the IS25C128/256 is required to receive.  
Serial Data Output (SO): This is the output pin for all  
datatransmittedfromtheIS25C128/256.
