CY7C460A集成电路（IC）的FIFO存储器规格书PDF中文资料

CY7C460A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CY7C460AFIFO 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 CY7C460A, CY7C462A, CY7C464A, and CY7C466A are respectively, 8K, 16K, 32K, and 64K words by 9-bit wide first-in first-out (FIFO) memories. Each FIFO memory is organized such that the data is read in the same sequential order that it was written. Full and Empty flags are provided to prevent overrun and underrun. Three additional pins are also provided to facilitate unlimited expansion in width, depth, or both. The depth expansion technique steers the control signals from one device to another by passing tokens.
