GENERAL DESCRIPTION
· Switchable organization
4,194,304x8(byte mode)
2,097,152x16(word mode)
· Fast access time
3.3V Operation : 120ns(Max.)
3.0V Operation : 150ns(Max.)
· Supply voltage : single +3.0V/ single +3.3V
· Current consumption
The K3N6V(U)1000C-GC is a fully static mask programmable
ROM fabricated using silicon gate CMOS process technology,
and is organized either as 4,194,304 x 8 bit(byte mode) or as
2,097,152 x 16 bit(word mode) depending on BHE voltage
level.(See mode selection table)
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.
Operating : 40mA(Max.)
Standby : 30mA(Max.)
It is suitable for use in program memory of microprocessor, and
data memory, character generator.
· Fully static operation
· All inputs and outputs TTL compatible
· Three state outputs
The K3N6V(U)1000C-GC is packaged in a 44-SOP.
· Package
-. K3N6V(U)1000C-GC : 44-SOP-600
