IDT7014S
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. This part lends itself to high-speed applications which do not rely
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-
Ports typically operate on only 750mW of power at maximum access times
as fast as 12ns.
The IDT7014 is packaged in a 52-pin PLCC and a 64-pin thin quad
flatpack, (TQFP).
