KM23V32005D(E)TY/KM23S32005D(E)TY

CMOS MASK ROM

32M-Bit (4Mx8 /2Mx16) CMOS MASK ROM

FEATURES

GENERAL DESCRIPTION

The KM23V32005D(E)TY and KM23S32005D(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 8 words (or 16 bytes) of data to read fast in the same

page, CE and A3 ~ A20 should not be changed.

· Switchable organization

4,194,304x8(byte mode)

2,097,152x16(word mode)

· Fast access time

Random Access Time/Page Access Time

3.3V/3.0V Operation : 100/30ns(Max.)

2.5V Operation : 150/50ns(Max.)

· 8 words/ 16 bytes page access

· Supply voltage

KM23V32005D(E)TY : single +3.0V/ single +3.3V

KM23S32005D(E)TY : single +2.5V

· Current consumption

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.

Operating : 60mA(Max.)

Standby : 30mA(Max.)

· Fully static operation

· All inputs and outputs TTL compatible

· Three state outputs

· Package

It is suitable for use in program memory of microprocessor, and

data memory, character generator.

The KM23V32005D(E)TY and KM23S32005D(E)TY are pack-

aged in a 48-TSOP1.

-. KM23V(S)32005D(E)TY : 48-TSOP1-1218
