I/O

DESCRIPTION

Almost-full/almost-empty flag. Depth offset values can be programmed for AF/AE, or the default value

of 8 can be used for both the AE offset (X) and the AF offset (Y). AF/AE is high when memory contains

X or fewer words or (64 – Y) or more words. AF/AE is high after reset.

18-bit data input port

Half-full flag. HF is high when the FIFO memory contains 32 or more words. HF is low after reset.

Input-ready flag. IR is synchronized to the low-to-high transition of WRTCLK. When IR is low, the FIFO

is full and writes are disabled. IR is low during reset and goes high on the second low-to-high transition

of WRTCLK after reset.

Output enables. When OE1, OE2, and RDEN are low and OR is high, data is read from the FIFO on

a low-to-high transition of RDCLK. When either OE1 or OE2 is high, reads are disabled and the data

outputs are in the high-impedance state.

Output-ready flag. OR is synchronized to the low-to-high transition of RDCLK. When OR is low, the

FIFO is empty and reads are disabled. Ready data is present on Q0–Q17 when OR is high. OR is low

during reset and goes high on the third low-to-high transition of RDCLK after the first word is loaded

to empty memory.

Program enable. After reset and before the first word is written to the FIFO, the binary value on D0–D4

is latched as an AF/AE offset value when PEN is low and WRTCLK is high.

The 18-bit data output port. After the first valid write to empty memory, the first word is output on

Q0–Q17 on the third rising edge of RDCLK. OR also is asserted high at this time to indicate ready data.

When OR is low, the last word read from the FIFO is present on Q0–Q17.

Read clock. RDCLK is a continuous clock and can be asynchronous or coincident to WRTCLK. A

low-to-high transition of RDCLK reads data from memory when OE1, OE2, and RDEN are low and OR

is high. OR is synchronous to the low-to-high transition or RDCLK.

Read enable. When RDEN, OE1, and OE2 are low and OR is high, data is read from the FIFO on the

low-to-high transition of RDCLK.

Reset. To reset the FIFO, four low-to-high transitions of RDCLK and four low-to-high transitions of

WRTCLK must occur while RESET is low. This sets HF, IR, and OR low and AF/AE high.

Write clock. WRTCLK is a continuous clock and can be asynchronous or coincident to RDCLK. A

low-to-high transition of WRTCLK writes data to memory when WRTEN2 is low, WRTEN1 is high, and

IR is high. IR is synchronous to the low-to-high transition of WRTCLK.

Write enables. When WRTEN1 is high, WRTEN2 is low, and IR is high, data is written to the FIFO on

a low-to-high transition of WRTCLK.
