M66258FP中文资料瑞萨数据手册PDF规格书

Description

The M66258FP 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 8192 words × 8 bits.

The M66258FP, 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: 8192 words × 8 bits configuration

• High speed cycle: 20 ns (Min)

• High speed access: 16 ns (Max)

• Output hold: 3 ns (Min)

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

• Variable length delay bit

• Input/output: TTL direct connection allowable

• Output: 3 states

Application

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