DESCRIPTION  
TheIS25C128andIS25C256areelectricallyerasable  
PROM devices that use the Serial Peripheral Interface  
(SPI) for communications. The IS25C128 is 128Kbit  
(16K x 8) and the IS25C256 is 256Kbit (32K x 8). The  
IS25C128/256 EEPROMs are offered in a wide  
operating voltage range of 1.8V to 5.5V for compatibility  
with most application voltages. ISSI designed the  
IS25C128/256 to be an efficient SPI EEPROM solution.  
The devices are packaged in 8-pin JEDEC SOIC, 8-pin  
EIAJ SOIC, and 8-pin PDIP.  
— Partial page writes allowed  
• 2.1 MHz Clock Rate (5V)  
• Self timed write cycles  
— 5ms max @ 2.5V  
• High-reliability  
— Endurance: 1,000,000 cycles per byte  
— Data retention: 100 years  
• 8-pin JEDEC SOIC, 8-pin EIAJ SOIC, and 8-pin PDIP  
packagesavailable  
• IndustrialandAutomotivetemperatureranges  
• Lead-freeavailable  
ThefunctionalfeaturesoftheIS25C128/256allowthem  
to be among the most advanced serial non-volatile  
memories available. Each device has a Chip-Select  
(CS) pin, and a 3-wire interface of Serial Data In (SI),  
Serial Data Out (SO), and Serial Clock (SCK). While  
the3-wireinterfaceoftheIS25C128/256providesfor  
high-speed access, a HOLD pin allows the memories to  
ignore the interface in a suspended state; later the  
HOLD pinre-activatescommunicationwithoutre-  
initializing the serial sequence. A Status Register  
facilitates a flexible write protection mechanism, and a  
device-readybit(RDY).
