DESCRIPTION (CONTINUED)

Full and almost Empty) to indicate when a selected number of

words is stored in memory. Communication between each

port may bypass the FIFOs via two 36-bit mailbox registers.

Each mailbox register has a flag to signal when new mail has

been stored. Two or more devices may be used in parallel to

create wider data paths.

The IDT723622/723632/723642 is a synchronous (clocked)

FIFO, meaning each port employs a synchronous interface.

All data transfers through a port are gated to the LOW-to-

HIGH transition of a port clock by enable signals. The clocks

for each port are independent of one another and can be

NOTES:

1. NC – no internal connection

2. Uses Yamaichi socket IC51-1324-828

asynchronous or coincident. The enables for each port are

arranged to provide a simple bidirectional interface between

microprocessors and/or buses with synchronous control.

The Input Ready (IRA, IRB) and Almost-Full (

AFA, AFB)

flags of a FIFO are two-stage synchronized to the port clock

that writes data into its array. The Output Ready (ORA, ORB)

and Almost-Empty (

AEA, AEB) flags of a FIFO are two-stage

synchronized to the port clock that reads data from its array.

Offset values for the Almost-Full and Almost-Empty flags of

both FIFOs can be programmed from Port A.

The IDT723622/723632/723642 is characterized for op-

eration from 0

°C to 70°C.
