Preliminary Information  
K3N7V(U)1000B-TC  
CMOS MASK ROM  
64M-Bit (8Mx8 /4Mx16) CMOS MASK ROM  
FEATURES  
GENERAL DESCRIPTION  
· Switchable organization  
8,388,608 x 8(byte mode)  
The K3N7V(U)1000B-TC is a fully static mask programmable  
ROM fabricated using silicon gate CMOS process technology,  
and is organized either as 8,388,608 x 8 bit(byte mode) or as  
4,194,304 x 16 bit(word mode) depending on BHE voltage  
level.(See mode selection table)  
4,194,304 x 16(word mode)  
· Fast access time  
3.3V Operation : 100ns(Max.)  
3.0V Operation : 120ns(Max.)  
· Supply voltage : single +3.0V/ single +3.3V  
· Current consumption  
This device operates with 3.0V or 3.3V power supply, and all  
inputs and outputs are TTL compatible.  
Because of its asynchronous operation, it requires no external  
clock assuring extremely easy operation.  
Operating : 40mA(Max.)  
Standby : 50mA(Max.)  
It is suitable for use in program memory of microprocessor, and  
data memory, character generator.  
· Fully static operation  
· All inputs and outputs TTL compatible  
· Three state outputs  
The K3N7V(U)1000B-TC is packaged in a 44-TSOP2.  
· Package : K3N7V(U)1000B-TC : 44-TSOP2-400
