FEATURES  
DESCRIPTION  
The X25170 is a CMOS 16384-bit serial E2PROM,  
internally organized as 2K x 8. The X25170 features a  
•5MHz Clock Rate  
•SPI Modes (0,0 & 1,1)  
•2K X 8 Bits  
Serial Peripheral Interface (SPI) and software protocol,  
allowing operation on a simple three-wire bus. The bus  
—32 byte page mode  
•Low Power CMOS  
signals are a clock input (SCK) plus separate data in (SI)  
and data out (SO) lines. Access to the device is  
—<1µA standby current  
—<5mA active current  
controlled through a chip select (CS) input, allowing any  
number of devices to share the same bus.  
•2.5V To 5.5V Power Supply  
•Block Lock Protection  
—Protect 1/4, 1/2 or all of E2PROM array  
The X25170 also features two additional inputs that  
provide the end user with added flexibility. By asserting  
Built-In Inadvertent Write Protection  
—Power-up/power-down protection circuitry  
the HOLD input, the X25170 will ignore transitions on its  
inputs, thus allowing the host to service higher prior-  
—Write enable latch  
—Write protect pin  
•Self-Timed Write Cycle  
ity interrupts. The WP input can be used as a hardwire 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.  
—5ms write cycle time (typical)  
•High Reliability  
—Endurance: 100,000 cycles  
—Data retention: 100 Years  
The X25170 utilizes Xicor’s proprietary Direct Writecell,  
providing a minimum endurance of 100,000 cycles and a  
minimum data retention of 100 years.  
—ESD protection: 2000V on all pins
