CY7C0430BV-100BGC集成電路（IC）的存儲器規(guī)格書PDF中文資料

Functional Description

The CY7C043XXBV is a family of 10 Gb/s, true four-ported Datapath Switching Elements with port speeds of up to 133 MHz[1]. The members of the family include 1-Mb (64K ×18), ?-Mb (32K x18), and ?-Mb (16K × 18) options. All four ports may be clocked at independent frequencies from one another. Simultaneous reads are allowed for accesses to the same address location; however, simultaneous reading and writing to the same address is not allowed. Any port can write to a certain location while other ports are reading that location simultaneously, if the timing spec for port to port delay (tCCS) is met. The result of writing to the same location by more than one port at the same time is undefined.
