DESCRIPTION
The IDT72V10071/72V11071/72V12071/72V13071/72V14071 are dual Multimedia FIFOs. The device is functionally equivalent to two independent
FIFOs in a single package with all associated control, data, and flag lines assigned to separate pins. Each of the two FIFOs (designated FIFO A and FIFO B) has a 8-bit input data port (DA0 - DA7, DB0 - DB7) and a 8-bit output data port (QA0 - QA7, QB0 - QB7). Each input port is controlled by a free-running clock (WCLKA, WCLKB), and a Write Enable pin (WENA, WENB). Data is written into each of the two arrays on every rising clock edge of the Write Clock (WCLKA, WCLKB) when the appropriate Write Enable pin is asserted. The output port of each FIFO bank is controlled by its associated clock pin (RCLKA, RCLKB) and Read Enable pin (RENA, RENB). The Read Clock can be tied to the Write Clock for single clock operation or the two clocks can run asynchronous of one another for dual clock operation. An Output Enable pin (OEA, OEB) is provided on the read port of each FIFO for three-state output control. Each of the two FIFOs has two fixed flags, Empty (EFA, EFB) and Full (FFA, FFB). This FIFO is fabricated using IDT's high-performance submicron CMOS technology.

PIN DESCRIPTIONS
The IDT72V10071/72V11071/72V12071/72V13071/72V14071's two FIFOs, referred to as FIFO A and FIFO B, are identical in every respect. FIFO A and FIFO B operate completely independent from each other. Symbol DA0-DA7 DB0-DB7 RSA, RSB Name A Data Inputs B Data Inputs Reset I/O I I I 8-bit data inputs to FIFO array A. 8-bit data inputs to FIFO array B. When RSA (RSB) is set LOW, the associated internal read and write pointers of array A (B) are set to the first location; FFA (FFB) go as HIGH and EFA (EFB) go as LOW. After power-up, a reset of both FIFOs A and B is required before an initial WRITE. Data is written into the FIFO A (B) on a LOW-to-HIGH transition of WCLKA (WCLKB) when the write enable is asserted.

When WENA (WENB) is LOW, data A (B) is written into the FIFO on every LOW-to-HIGH transition WCLKA (WCLKB). Data will not be written into the FIFO if FFA (FFB) is LOW. O 8-bit data outputs from FIFO array A. O 8-bit data outputs from FIFO array B. I Data is read from FIFO A (B) on a LOW-to-HIGH transition of RCLKA (RCLKB) when RENA (RENB) is asserted. I I When RENA (RENB) is LOW, data is read from FIFO A (B) on every LOW-to-HIGH transition of RCLKA (RCLKB). Data will not be read from Array A (B) if EFA (EFB) is LOW. When OEA (OEB) is LOW, outputs DA0-DA7 (DB0-DB7) are active. If OEA (OEB) is HIGH, outputs DA0-DA7 (DB0-DB7) will be in a high-impedance state.
O When EFA (EFB) is LOW, FIFO A (B) is empty and further data reads from the output are inhibited. When EFA (EFB) is HIGH, FIFO A (B) is not empty. EFA (EFB) is synchronized to RCLKA (RCLKB). O When FFA (FFB) is LOW, FIFO A (B) is full and further data writes into the input are inhibited. When FFA (FFB) is HIGH, FIFO A (B) is not full. FFA (FFB) is synchronized to WCLKA (WCLKB). +3.3V power supply pin. 0V ground pin.

SIGNAL DESCRIPTIONS
FIFO A and FIFO B are identical in every respect. The following description explains the interaction of input and output signals for FIFO A. The corresponding signal names for FIFO B are provided in parentheses.
INPUTS
Data In (DA0 - DA7, DB0 - DB7) -- DA0 - DA7 are the eight data inputs for memory array A. DB0 - DB7 are the eight data inputs for memory array B.
CONTROLS
Reset (RSA, RSB) -- Reset of FIFO A (B) is accomplished whenever RSA (RSB) input is taken to a LOW state. During reset, the internal read and write pointers associated with the FIFO are set to the first location. A reset is required after power-up before a write operation can take place. The Full Flag, FFA (FFB) will be reset to HIGH after tRSF. The Empty Flag, EFA (EFB) will be reset to LOW after tRSF. During reset, the output register is initialized to all zeros. Write Clock (WCLKA, WCLKB) -- A write cycle to Array A (B) is initiated on the LOW-to-HIGH transition of WCLKA (WCLKB). Data set-up and hold times must be met with respect to the LOW-to-HIGH transition of WCLKA (WCLKB). The Full Flag, FFA (FFB) is synchronized with respect to the LOW-to-HIGH transition of the Write Clock, WCLKA (WCLKB). The Write and Read clock can be asynchronous or coincident. Write Enable (WENA, WENB) -- When WENA (WENB) is LOW, data can be loaded into the input register of RAM Array A (B) on the LOW-to-HIGH transition of every Write Clock, WCLKA (WCLKB). Data is stored in Array A (B) sequentially and independently of any on-going read operation. When WENA (WENB) is HIGH, the input register holds the previous data and no new data is allowed to be loaded into the register. To prevent data overflow, FFA (FFB) will go LOW, inhibiting further write operations. Upon the completion of a valid read cycle, the FFA (FFB) will go HIGH after tWFF, allowing a valid write to begin. WENA (WENB) is ignored when FIFO A (B) is full. Read Clock (RCLKA, RCLKB) -- Data can be read from Array A (B) on the LOW-to-HIGH transition of RCLKA (RCLKB). The Empty Flag, EFA (EFB) is synchronized with respect to the LOW-to-HIGH transition of RCLKA (RCLKB). The Write and Read Clock can be asynchronous or coincident.
Read Enable (RENA, RENB) -- When Read Enable, RENA, (RENB) is LOW, data is read from Array A (B) to the output register on the LOW-to-HIGH transition of the Read Clock, RCLKA (RCLKB). When Read Enable, RENA, (RENB) for FIFO A (B) is HIGH, the output register holds the previous data and no new data is allowed to be loaded into the register. When all the data has been read from FIFO A (B), the Empty Flag, EFA (EFB) will go LOW, inhibiting further read operations. Once a valid write operation has been accomplished, EFA (EFB) will go HIGH after tREF and a valid read can begin. The Read Enable, RENA, (RENB) is ignored when FIFO A (B) is empty. Output Enable (OEA, OEB) -- When Output Enable, OEA (OEB) is enabled (LOW), the parallel output buffers of FIFO A (B) receive data from their respective output register. When Output Enable, OEA (OEB) is disabled (HIGH), the QA (QB) output data bus is in a high-impedance state.
OUTPUTS
Full Flag (FFA, FFB) -- FFA (FFB) will go LOW, inhibiting further write operations, when Array A (B) is full. If no reads are performed after reset, FFA (FFB) will go LOW after 256 writes to the IDT72V10071's FIFO A (B), 512 writes to the IDT72V11071's FIFO A (B), 1,024 writes to the IDT72V12071's FIFO A (B), 2,048 writes to the IDT72V13071's FIFO A (B), and 4,096 writes to the IDT72V14071's FIFO A (B). FFA (FFB) is synchronized with respect to the LOW-to-HIGH transition of the Write Clock WCLKA (WCLKB). Empty Flag (EFA, EFB) -- EFA (EFB) will go LOW, inhibiting further read operations, when the read pointer is equal to the write pointer, indicating that Array A (B) is empty. EFA (EFB) is synchronized with respect to the LOW-to-HIGH transition of the Read Clock RCLKA (RCLKB). Data Outputs (QA0 - QA7, QB0 - QB7 ) -- QA0 - QA7 are the eight data outputs for memory array A, QB0 - QB7 are the eight data outputs for memory array B.
