FEATURES  
DESCRIPTION  
The X24645 is a CMOS 65,536-bit serial E2PROM,  
internally organized 8192 x 8. The X24645 features a  
•2.7V to 5.5V Power Supply  
•Low Power CMOS  
—Active Read Current Less Than 1mA  
—Active Write Current Less Than 3mA  
serial interface and software protocol allowing operation  
on a simple two wire bus.  
—Standby Current Less Than 1∝A  
•Internally Organized 8192 x 8  
•New Programmable Block Lock Protection  
—Software Write Protection  
—Programmable hardware Write Protect  
Two device select inputs (S1, S2) allow up to four  
devices to share a common two wire bus.  
A Write Protect Register at the highest address location,  
1FFFh, provides three new write protection

•Block Lock (0, 1/4, 1/2, or all of the E PROM  
array)  
features: Software Write Protect, Block Write Protect, and  
Hardware Write Protect. The Software Write  
•2 Wire Serial Interface  
Protect feature prevents any nonvolatile writes to the  
X24645 until the WEL bit in the write protect register is  
•Bidirectional Data Transfer Protocol  
•32 Byte Page Write Mode  
—Minimizes Total Write Time Per Byte  
•Self Timed Write Cycle  
—Typical Write Cycle Time of 5ms  
•High Reliability  
—Endurance: 100,000 Cycles  
—Data Retention: 100 Years  
•Available Packages  
set. The Block Write Protection feature allows the user to  
individually write protect four blocks of the array by  
programming two bits in the write protect register. The  
Programmable Hardware Write Protect feature allows  
the user to install the X24645 with WP tied to VCC,  
program the entire memory array in place, and then  
enable the hardware write protection by programming a  
WPEN bit in the write protect register. After this,  
—8-Lead PDIP  
selected blocks of the array, including the write protect  
register itself, are permanently write protected, as long  
as WP remains HIGH.
