DESCRIPTION:
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 and expansion logic to allow for unlimited expansion capability in both word size and depth.
The reads and writes are internally sequential through the use of ring pointers, with no address information required to load and unload data. Data is toggled in and out of the devices through the use of the Write (W) and Read (R) pins.
The devices utilize 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.
These FIFOs are fabricated using 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 MIL-STD-883, Class B.

FEATURES:
• First-In/First-Out dual-port memory
• 256 x 9 organization (IDT7200)

   — Active: 440mW (max.)
   —Power-down: 28mW (max.)
• Ultra high speed—12ns access time
• Asynchronous and simultaneous read and write
• Fully expandable by both word depth and/or bit width
• 720x family is pin and functionally compatible from 256 x 9 to 64k x 9
• Status Flags: Empty, Half-Full, Full
• 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
• Dual versions available in the TSSOP package. For more information, see IDT7280/7281/7282 data sheet
