CMOS MASK ROM
GENERAL DESCRIPTION
The KM23V64015BF is a fully static mask programmable ROM
fabricated using silicon gate CMOS process technology, and is
organized either as 8,388,608 x 8 bit(byte mode) or as 4,194,304
x 16 bit(word mode) depending on BHE voltage level. This
device includes page read mode function, page read mode
allows 8 words (or 16 bytes) of data to be read fast in the same
page, CE and A

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
operating system and/or application software storage for hand-
held application.
The KM23V64015BF is packaged in a 48-CSP with 0.75mm ball
pitch and 6x8 ball array.
