DESCRIPTION:
TheIDT7200/7201/7202aredual-portmemoriesthatloadandemptydata
onafirst-in/first-outbasis. ThedevicesuseFullandEmptyflagstopreventdata
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)andRead
(
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
applicationswhereitisnecessarytouseaparitybitfortransmission/reception
errorchecking. ItalsofeaturesaRetransmit(
RT)capabilitythatallowsforreset
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 IDT’s high-speed CMOS technology.
They are designed for those applications requiring asynchronous and
simultaneous read/writes in multiprocessing and rate buffer applications.
