Commercial And Industrial Temperature Ranges
After half of the memory is filled, and at the LOW-to-HIGH
transition of the next write cycle, the Half-Full Flag goes LOW
and will remain set until the difference between the write
pointer and read pointer is less than or equal to one half of the
total memory of the device. The Half-Full Flag (
HF) is then
reset to HIGH by the LOW-to-HIGH transition of the read clock
(RCLK). The
HF is asynchronous.
In the Daisy Chain Depth Expansion mode,
WXI is connected
to
WXOof the previous device. This output acts as a signal to the
next device in the Daisy Chain by providing a pulse when the
previous device writes to the last location of memory.
READ EXPANSION OUT (
RXO
RXO)
In the Daisy Chain Depth Expansion configuration, Read
Expansion In (
RXI) is connected to Read Expansion Out (RXO)
of the previous device. This output acts as a signal to the next
device in the Daisy Chain by providing a pulse when the
previous device reads from the last location of memory.
DATA OUTPUTS (Q0-Q17)
Q0-Q17 are data outputs for 18-bit wide data.

NOTES:
1. After reset, the outputs will be LOW if
OE = 0 and tri-state if OE = 1.
2. The clocks (RCLK, WCLK) can be free-running during reset.
