Standby : 30mA(Max.)  
· Fully static operation  
· All inputs and outputs TTL compatible  
· Three state outputs  
The KM23V16000D(G) is a fully static mask programmable  
ROM fabricated using silicon gate CMOS process technology,  
and is organized either as 2,097,152 x 8 bit(byte mode) or as  
1,048,576x16 bit(word mode) depending on BHE voltage  
level.(See mode selection table)  
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.  
It is suitable for use in program memory of microprocessor, and  
data memory, character generator.  
· Package  
-. KM23V16000D : 42-DIP-600  
-. KM23V16000DG : 44-SOP-600  
The KM23V16000D is packaged in  
KM23V16000DG in a 44-SOP.
