72271中文资料32K x 9 SuperSync FIFO, 5.0V数据手册Renesas规格书

描述 Description

The 72271 is a 32K x 9 SuperSync FIFO memory with clocked read and write controls.The Frequency Select pin (FS) has been removed, thus it is no longer necessary to select which of the two clock inputs, RCLK or WCLK, is running at the higher frequency.The period required by the retransmit operation and the first word data latency period is now fixed and short. (The variable clock cycle counting delay associated with the latency period found on previous SuperSync devices has been eliminated on this SuperSync family.)
