16M-Bit (2Mx8 /1Mx16) CMOS MASK ROM
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.
The KM23V16000D is packaged in a 42-DIP and the
KM23V16000DG in a 44-SOP.
