The KM23V32005BG 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 includes page read mode function, page read mode allows 8 words(or 16 bytes) of data to read fast in the same page, CE and A3 ~ A20 should not be changed. This device operates with a 3.3V 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 KM23V32005BG is packaged in a 44-SOP.
