4M-Bit (512Kx8) CMOS MASK ROM
The K3N3V(U)3000D-D(G)C is a fully static mask programma-
ble ROM organized 524,288 x 8 bit. It is fabricated using silicon
gate CMOS process technology.
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.
The K3N3V(U)3000D-DC is packaged in a 32-DIP and the
K3N3V(U)3000D-GC in a 32-SOP.
