4 Megabit Puma Module  
512K x 8 Bit  
XM28C040P  
High Density 5 Volt Byte Alterable Nonvolatile Memory Array  
FEATURES  
DESCRIPTION  
• High Density Memory Module  
—150ns, 200ns, and 250ns Access Times  
Available  
—4 Megabit Memory in 1 square inch.  
• Flexible Multiplane Architecture  
—Four Separate Chip Selects  
—32 Separate I/Os  
• User Configurable I/Os—x8, x16, or x32  
• User Configurable Page Size—64 Double-  
words, 128 Words, or 256 Bytes  
—Concurrent Read/Write Operations  
• Able to Continue Reading During a  
Nonvolatile Write Cycle.  
The XM28C040P is a high density CMOS byte alter-  
able nonvolatile memory array constructed on a co-  
fired ceramic substrate using Xicor’s 128K x 8 compo-  
nents in 32-pad leadless chip carriers. The Substrate is  
a 66-pin ceramic pin grid array.  
The module is configured with four separate chip  
enable and write enable inputs and 32 separate I/Os.  
This, along with the small footprint, provides the end  
user with a large degree of flexibility in board layout and  
memory configuration. In addition, with the large num-  
ber of pins and the growth path being implemented, the  
module will be able to grow to 16 megabits.  
• 5 Volt Byte or Page Alterable  
—No Erase Before Write  
• Software Data Protection  
• Early End of Write Polling  
DATA Polling  
Toggle Bit Polling  
• High Reliability  
—Endurance: 100,000 Cycles  
—Data Retention: 100 Years
