4M-Bit (512Kx8) CMOS MASK ROM
The KM23C4000D(G) is a fully static mask programmable
ROM organized 524,288x8 bit. It is fabricated using silicon gate
CMOS process technology.
This device operates with a 5V single 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 KM23C4000D is packaged in a 32-DIP and the
KM23C4000DG in a 32SOP.
