KM23C8105D(E)T : 44-TSOP2-400 CMOS MASK ROM GENERAL DESCRIPTION The KM23C8105D(E)T is a fully static mask programmable ROM fabricated using silicon gate CMOS process technology, and is organized either as 1,048,576 x 8 bit(byte mode) or as 524,288 x 16 bit(word mode) depending on BHE voltage level.(See mode selection table) This device includes page read mode function, page read mode allows 4 words (or 8bytes) of data to read fast in the same page, CE and A 2 ~ A18 should not be changed. 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 KM23C8105D(E)T is packaged in a 44-TSOP2.
