DESCRIPTION:  
First-In/First-Out dual-port memory  
256 x 9 organization (IDT7200)  
512 x 9 organization (IDT7201)  
1K x 9 organization (IDT7202)  
The IDT7200/7201/7202 are dual-port memories that load  
and empty data on a first-in/first-out basis. The devices use  
Full and Empty flags to prevent data overflow and underflow  
andexpansionlogictoallowforunlimitedexpansioncapability  
in both word size and depth.  
Low power consumption  
— Active: 770mW (max.)  
—Power-down: 2.75mW (max.)  
Ultra high speed—12ns access time  
Asynchronous and simultaneous read and write  
Fully expandable by both word depth and/or bit width  
Pin and functionally compatible with 720X family  
Status Flags: Empty, Half-Full, Full  
The reads and writes are internally sequential through the  
use of ring pointers, with no address information required to  
loadandunloaddata. Dataistoggledinandoutofthedevices  
through the use of the Write (W) and Read (R) pins.  
The devices utilizes a 9-bit wide data array to allow for  
control and parity bits at the user’s option. This feature is  
especially useful in data communications applications where  
it is necessary to use a parity bit for transmission/reception  
error checking. It also features a Retransmit (RT) capability  
that allows for reset of the read pointer to its initial position  
when RT is pulsed low to allow for retransmission from the  
beginning of data. A Half-Full Flag is available in the single  
device mode and width expansion modes.  
The IDT7200/7201/7202 are fabricated using IDT’s high-  
speed CMOS technology. They are designed for those  
applications requiring asynchronous and simultaneous read/  
writes in multiprocessing and rate buffer applications. Military  
grade product is manufactured in compliance with the latest  
revision of MIL-STD-883, Class B.  
Auto-retransmit capability  
High-performance CEMOS technology  
Military product compliant to MIL-STD-883, Class B  
Standard Military Drawing #5962-87531, 5962-89666,  
5962-89863 and 5962-89536 are listed on this function  
Industrial temperature range (-40oC to +85oC) is  
available, tested to military electrical specifications
