FEATURES
GENERAL DESCRIPTION
524,288 x 8 bit organization
The KM23V4000D(E)TY and KM23S4000D(E)TY are fully
Fast access time
static mask programmable ROM organized 524,288 x 8 bit. It is
3.3V Operation : 100ns(Max.)
fabricated using silicon gate CMOS process technoiogy.
3.0V Operation : 120ns(Max.)
2.5V Operation : 250ns(Max.)
Supply voltage
KM23V4000D(E)TY : single +3.0V/ single +3.3V
KM23S4000D(E)TY : single +2.5V
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.
Current consumption
It is suitable for use in program memory of microprocessor, and
Operating : 25mA(Max.)
Standby : 30µA(Max.)
Fully static operation
mAll inputs and outputs TTL compatible
Three state outputs
oPackage
-. KM23V(S)4000D(E)TY : 32-TSOP1-0820
data memory, character generator.
The KM23V4000D(E)TY and KM23S4000D(E)TY are pack-
aged in a 32-TSOP1.
