-. K3P6C2000B-SC : 70-SSOP-500
CMOS MASK ROM
GENERAL DESCRIPTION
The K3P6C2000B-SC 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 A

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 K3P6C2000B-SC is packaged in a 70-SSOP.
