· Current consumption
The K3P7C1000B-TC is a fully static mask programmable
ROM fabricated using silicon gate CMOS process technology,
and is organized either as 8,388,608 x 8 bit(byte mode) or as
4,194,304 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 8 words (or 16 bytes) of data to read fast in the same
page, CE and A3 ~ A21 should not be changed.
: 30ns(Max.)
This device operates with a 5V single power supply, and all
inputs and outputs are TTL compatible.
Operating : 150mA(Max.)
Standby : 100mA(Max.)
· Fully static operation
· All inputs and outputs TTL compatible
· Three state outputs
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.
· Package
-. K3P7C1000B-TC : 44-TSOP2-400
The K3P7C1000B-TC is packaged in a 44-TSOP2.
