CY7C4281V-15JC中文资料赛普拉斯数据手册PDF规格书

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.

Features

• 3.3V operation for low power consumption and easy

integration into low-voltage systems
