FEATURES  
DESCRIPTION  
The X25320 is a CMOS 32768-bit serial E2PROM,  
internally organized as 4K x 8. The X25320 features a  
•2MHz Clock Rate  
•SPI Modes (0,0 & 1,1)  
•4K 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 con-  
—<1µA Standby Current  
— <5mA Active Current During Write  
•2.7V To 5.5V Power Supply  
•Block Lock Protection  
— Protect 1/4, 1/2 or all of E2PROM Array  
•Built-in Inadvertent Write Protection  
trolled through a chip select (CS) input, allowing any  
number of devices to share the same bus.  
The X25320 also features two additional inputs that  
provide the end user with added flexibility. By asserting  
the HOLD input, the X25320 will ignore transitions on its  
inputs, thus allowing the host to service higher priority  
— Power-Up/Power-Down protection circuitry  
— Write Enable Latch  
interrupts. The WP input can be used as a hardwire input to  
the X25320 disabling all write attempts to the status  
— Write Protect Pin  
•Self-Timed Write Cycle  
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 X25320 utilizes Xicor’s proprietary Direct Write™ cell,  
providing a minimum endurance of 100,000 cycles  
and a minimum data retention of 100 years.  
— ESD protection: 2000V on all pins
