PIN CONFIGURATION
KM23V4100D(G)
The KM23V4100D(G) is a fully static mask programmable ROM
fabricated using silicon gate CMOS process technology, and is
organized either as 524,288 x 8bit(byte mode) or as 262,144 x
16bit(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 KM23V4100D is packaged in a 40-DIP and the
KM23V4100DG is a 40-SOP.
