K3N5V(U)1000D-D(G)C
CMOS MASK ROM
16M-Bit (2Mx8 /1Mx16) CMOS MASK ROM
FEATURES
GENERAL DESCRIPTION
· Switchable organization
The K3N5V(U)1000D-D(G)C is a fully static mask programma-
ble ROM fabricated using silicon gate CMOS process technol-
ogy, and is organized either as 2,097,152 x 8 bit(byte mode) or
as 1,048,576x16 bit(word mode) depending on BHE voltage
level.(See mode selection table)
2,097,152 x 8(byte mode)
1,048,576 x 16(word mode)
· Fast access time : 100ns(Max.)
· Supply voltage : single +3.0V/ single +3.3V
· Current consumption
Operating : 40mA(Max.)
Standby : 30mA(Max.)
· Fully static operation
· All inputs and outputs TTL compatible
· Three state outputs
This device operates with 3.0V or 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.
· Package
-. K3N5V(U)1000D-DC : 42-DIP-600
-. K3N5V(U)1000D-GC : 44-SOP-600
The K3N5V(U)1000D-DC is packaged in a 42-DIP and the
K3N5V(U)1000D-GC in a 44-SOP.
