KM23C32000CG : 44-SOP-600 CMOS MASK ROM GENERAL DESCRIPTION The KM23C32000CG is a fully static mask programmable ROM fabricated using silicon gate CMOS process technology, and is organized either as 4,194,304x8 bit(byte mode) or as 2,097,152x16 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 patible. 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 KM23C32000CG is packaged in a 44-SOP. FUNCTIONAL BLOCK DIAGRAM PIN CONFIGURATION A20 - . . .
