4M-Bit (512Kx8) CMOS MASK ROM
The KM23V4000D(E)TY and KM23S4000D(E)TY are fully
static mask programmable ROM organized 524,288 x 8 bit. It is
fabricated using silicon gate CMOS process technoiogy.
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 KM23V4000D(E)TY and KM23S4000D(E)TY are pack-
aged in a 32-TSOP1.
