M66280FP

5120 × 8-Bit Line Memory

Description

The M66280FP is high speed line memory that uses high performance silicon gate CMOS process technology and

adopts the FIFO (First In First Out) structure consisting of 5120 words × 8 bits.

The M66280FP, performing reading and writing operations at different cycles independently and asynchronously, is

optimal for buffer memory to be used between equipment of different data processing speeds.

Features

• Memory configuration:

• High speed cycle:

• High speed access:

• Output hold:

• Reading and writing operations can be completely carried out independently and asynchronously

• Variable length delay bit

• Input/output:

• Output:

Application

Digital copying machine, laser beam printer, high speed facsimile, etc.
