Description:

The IDT7014 is a high-speed 4K x 9 Dual-Port Static RAM designed

to be used in systems where on-chip hardware port arbitration is not

needed.Thispart lendsitselftohigh-speedapplicationswhichdonotrely

on BUSY signals to manage simultaneous access.

The IDT7014 provides two independent ports with separate control,

address, and I/O pins that permit independent, asynchronous access for

reads or writes to any location in memory. See functional description.

The IDT7014 utilitizes a 9-bit wide data path to allow for parity at the

user's option. This feature is especially useful in data communication

applications where it is necessary to use a parity bit for transmission/

reception error checking.

Fabricated using IDT’s high-performance technology, these Dual-

Portstypicallyoperateononly750mWofpoweratmaximumaccesstimes

as fast as 12ns.

The IDT7014 is packaged in a 52-pin PLCC and a 64-pin thin quad

flatpack, (TQFP).
