CMOS MASK ROM
GENERAL DESCRIPTION
The KM23C8100D(E)T is a fully static mask programmable ROM fabricated using silicon gate CMOS process technology, and is organized either as 1,048,576 x8 bit(byte mode) or as 524,288 x16 bit(word mode) depending on BHE voltage level.(See mode selection table) This device operates with a 5V single 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 KM23C8100D(E)T is packaged in a 44-TSOP2.
