CMOS MASK ROM
8M-Bit (1Mx8 /512Kx16) CMOS MASK ROM
FEATURES
GENERAL DESCRIPTION
· Switchable organization
1,048,576 x 8(byte mode)
524,288 x 16(word mode)
· Fast access time
The K3P4C1000D-TC(E) 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 A2 ~ A18 should not be changed.
Random Access : 100ns(Max.)
Page Access
: 30ns(Max.)
· 4 Words / 8 bytes page access
· Supply voltage : single +5V
· Current consumption
This device operates with a 5V single power supply, and all
inputs and outputs are TTL compatible.
Operating : 80mA(Max.)
Standby : 50mA(Max.)
· Fully static operation
· All inputs and outputs TTL compatible
· Three state outputs
· Package
-. K3P4C1000D-TC(E) : 44-TSOP2-400
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 K3P4C1000D-TC(E) is packaged in a 44-TSOP2.
