CMOS MASK ROM
GENERAL DESCRIPTION
The KM23V32205BSG is a fully static mask programmable ROM fabricated using silicon gate CMOS process technology, and is organized either as 2,097,152x16 bit(word mode) or as 1,048,576x32 bit(double word mode) depending on WORD voltage level.(See mode selection table) This device includes page read mode function, page read mode allows 4 double words(or 8 words) of data to read fast in the same page, CE and A2 ~ A19 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 KM23V32205BSG is packaged in a 70-SSOP.
