FEATURES  
DESCRIPTION  
• 5MHz clock rate  
• SPI modes (0,0 & 1,1)  
• 2K X 8 bits  
—32-byte page mode  
• Low power CMOS  
—<1µA standby current  
—<5mA active current  
• 2.5V To 5.5V power supply  
• Block lock protection  
The X25170 is a CMOS 16384-bit serial EEPROM,  
internally organized as 2K x 8. The X25170 features a  
Serial Peripheral Interface (SPI) and software protocol,  
allowing operation on a simple three-wire bus. The bus  
signals are a clock input (SCK) plus separate data in  
(SI) and data out (SO) lines. Access to the device is  
controlled through a chip select (CS) input, allowing  
any number of devices to share the same bus.  
The X25170 also features two additional inputs that  
provide the end user with added flexibility. By asserting  
the HOLD input, the X25170 will ignore transitions on  
its inputs, thus allowing the host to service higher pri-  
ority interrupts. The WP input can be used as a hard-  
wire input to the X25170 (disabling all write attempts to  
the status register), thus providing a mechanism for  
limiting end user capability of altering 0, 1/4, 1/2 or all  
of the memory.  
—Protect 1/4, 1/2 or all of EEPROM array  
• Built-in inadvertent write protection  
Power-up/power-down protection circuitry  
—Write enable latch  
—Write protect pin  
• Self-timed write cycle  
—5ms write cycle time (typical)  
• High reliability  
—Endurance: 1,000,000 cycles  
—Data retention: 100Years  
—ESD protection: 2000V on all pins  
• 8-lead SOIC package  
The X25170 utilizes Xicor’s proprietary Direct Write™  
cell, providing a minimum endurance of 1,000,000  
cycles and a minimum data retention of 100 years.
