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 a 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).

Absolute Maximum Ratings

(1)

NOTES:

1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may

cause permanent damage to the device. This is a stress rating only and functional

operation of the device at these or any other conditions above those indicated

in the operational sections of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect reliability.

2. V

TERM must not exceed Vcc + 10% for more than 25% of the cycle time or 10ns

maximum, and is limited to < 20mA for the period of VTERM > Vcc + 10%.
