PIN DESCRIPTION (BGA PACKAGE ONLY)
Symbol
Name
I/O
Description
ASYR(1)
Asynchronous
I
A HIGH on this input during Master Reset will select Synchronous read operation for the output port. A LOW
Read Port
will select Asynchronous operation. If Asynchronous is selected the FIFO must operate in IDT Standard mode.
ASYW(1)
Asynchronous
I
A HIGH on this input during Master Reset will select Synchronous write operation for the input port. A LOW
WritePort
will select Asynchronous operation.
TCK(2)
JTAG Clock
I
Clock input for JTAG function. One of four terminals required by IEEE Standard 1149.1-1990. Test operations of the
device are synchronous to TCK. Data from TMS and TDI are sampled on the rising edge of TCK and outputs change
on the falling edge of TCK. If the JTAG function is not used this signal needs to be tied to GND.
TDI(2)
JTAG Test Data
I
One of four terminals required by IEEE Standard 1149.1-1990. During the JTAG boundary scan operation, test data

An internal pull-up resistor forces TDI HIGH if left unconnected.

I
TMSisaserialinputpin.OneoffourterminalsrequiredbyIEEEStandard1149.1-1990.TMSdirectsthedevicethrough
its TAP controller states. An internal pull-up resistor forces TMS HIGH if left unconnected.
TRST(2)
JTAG Reset
I
TRST is an asynchronous reset pin for the JTAG controller. The JTAG TAP controller does not automatically reset
upon power-up, thus it must be reset by either this signal or by setting TMS= HIGH for five TCK cycles. If the TAP
controller is not properly reset then the FIFO outputs will always be in high-impedance. If the JTAG function is used
but the user does not want to use
TRST, then TRST can be tied with MRS to ensure proper FIFO operation. If the
JTAG function is not used then this signal needs to be tied to GND.
RM(1)
RetransmitTiming
I
During Master Reset, a LOW on RM will select zero latency Retransmit timing Mode. A HIGH on RM will select
Mode
normal latency mode.
RT
Retransmit
I
RT asserted on the rising edge of RCLK initializes the READ pointer to zero, sets the EF flag to LOW (OR to HIGH
in FWFT mode) and does not disturb the write pointer, programming method, existing timing mode or programmable
flag settings.
RT is useful to reread data from the first physical location of the FIFO.
SEN
Serial Enable
I
SENenablesserialloadingofprogrammableflagoffsets.
WCLK/
WriteClock/
I
If Synchronous operation of the write port has been selected, when enabled by
WEN, the rising edge of WCLK
WR
WriteStrobe
writes data into the FIFO. If Asynchronous operation of the write port has been selected, WR writes data into the
FIFO on a rising edge in an Asynchronous manner, (
WENshouldbetiedtoitsactivestate).Asynchronousoperation
of the WCLK/WR input is only available in the BGA package.
WEN
WriteEnable
I
WEN enables WCLK for writing data into the FIFO memory and offset registers.
VCC
+3.3V Supply
I
These are VCC supply inputs and must be connected to the 3.3V supply rail.
NOTE:
1. Inputs should not change state after Master Reset.
