PIN CONFIGURATIONS
DESCRIPTION:
The IDT7201A17202A is a dual port memory that utilizes a
special First-In, First-Out algorithm that loads and empties data
on a first-in, first-out basis. The device uses 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 device through the
use of the WRITE (W) and READ (A) pins. The device has a
read/write cycle time of 45ns (22MHz).
The device 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 featues a RETRANSM IT (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 IDT7201A17202A is fabricated using the high speed
CEMOS II, 1.2 micron technology and is available in DIPs and
LCCs screened to MIL-STD-883, Method 5004. It is designed for
those applications requiring asynchronous and simultaneous
read/writes in multiprocessing and rate buffer applications. The
1024 x 9 organization of the IDT7202A allows a 1024 deep word
structure without the need for expansion.
