KM23V32000D(E)TY/KM23S32000D(E)TY
CMOS MASK ROM
32M-Bit (4Mx8 /2Mx16) CMOS MASK ROM
FEATURES
GENERAL DESCRIPTION
• Switchable organization
The KM23V32000D(E)TY and KM23S32000D(E)TY are fully
4,194,304x8(byte mode)
static mask programmable ROM fabricated using silicon gate
2,097,152x16(word mode)
CMOS process technology, and is organized either as
• Fast access time
4,194,304 x8 bit(byte mode) or as 2,097,152x16 bit(word
Random Access Time
3.3V/3.0V Operation : 100ns(Max.)
2.5V Operation : 150ns(Max.)
mode) depending on BHE voltage level.(See mode selection
table)
• Supply voltage
This device operates with low power supply, and all inputs and
KM23V32000D(E)TY : single +3.0V/ single +3.3V
KM23S32000D(E)TY : single +2.5V
• Current consumption
mOperating : 40mA(Max.)
Standby : 30µA(Max.)
o• Fully static operation
• All inputs and outputs TTL compatible
.c• Three state outputs
• Package
-. KM23V(S)32000D(E)TY : 48-TSOP1-1218
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 KM23V32000D(E)TY and KM23S32000D(E)TY are pack-
aged in a 48-TSOP1.
