CY7C4291V集成电路（IC）的FIFO存储器规格书PDF中文资料

CY7C4291V属于集成电路（IC）的FIFO存储器。由赛普拉斯半导体公司制造生产的CY7C4291VFIFO 存储器先入先出 (FIFO) 存储器可用于数字信息的短期存储，其中信息检索顺序和序列与信息存储顺序和序列相同。这类产品又称为队列或缓冲存储器，通常用于在单独的设备之间交换信息，尤其是在数据以不同的速率或在略微不同的时间点生成和使用的情况下。

Functional Description

The CY7C4261/71/81/91V are high-speed, low-power FIFO memories with clocked read and write interfaces. All are nine bits wide. The CY7C4261/71/81/91V are pin-compatible to the CY7C42x1V Synchronous FIFO family.
