GENERAL DESCRIPTION
The KM23V8105D(G) is a fully static mask programmable ROM
fabricated using silicon gate CMOS process technology, and is
organized either as 1,048,576 x 8 bit(byte mode) or as 524,288
x 16 bit(word mode) depending on BHE voltage level.(See
mode selection table)
This device includes PAGE read mode function, page read
mode allows 4 words(or 8 bytes) of data to read fast in the
same page, CE and A2 ~ A18 should not be changed.
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 KM23V8105D is packaged in a 42-DIP and the
KM23V8105DG in a 44-SOP.
