KM23V32005B(E)TY/KM23S32005B(E)TY
CMOS MASK ROM
Preliminary
32M-Bit (4Mx8 /2Mx16) CMOS MASK ROM
The KM23V32005B(E)TY and KM23S32005B(E)TY are fully
static mask programmable ROM fabricated using silicon gate
CMOS process technology, and is organized either as 4,194,304
x8 bit(byte mode) or as 2,097,152x16 bit(word mode) depending
on BHE voltage level.(See mode selection table)
This device includes page read mode function, page read mode
allows four to eight words of data to read fast in the same page,

should not be changed.
This device operates with low 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 KM23V32005B(E)TY and KM23S32005B(E)TY are pack-
aged in a 48-TSOP1.
