The device is functionally equivalent to two IDT72V201/72V211/72V221/72V231/72V241/72V251 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) contained in the IDT72V801/72V811/72V821/72V831/72V841/72V851 has a 9-bit input data port (DA0 - DA8, DB0 - DB8) and a 9-bit output data port (QA0 - QA8, QB0 - QB8). Each input port is controlled by a free-running clock (WCLKA, WCLKB), and two Write Enable pins ( WENA1, WENA2, WENB1, WENB2). DataiswrittenintoeachofthetwoarraysoneveryrisingclockedgeoftheWrite Clock (WCLKA, WCLKB) when the appropriate Write Enable pins are asserted. The output port of each FIFO bank is controlled by its associated clock pin (RCLKA, RCLKB) and two Read Enable pins ( RENA1, RENA2, RENB1, RENB2).TheReadClockcanbetiedtotheWriteClockforsingleclockoperation orthetwoclockscanrunasynchronousofoneanotherfordualclockoperation. 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)andFull(FFA, FFB). Twoprogrammableflags,Almost-Empty(PAEA,PAEB)andAlmost-Full ( PAFA,PAFB),areprovidedforeachFIFObanktoimprovememoryutilization. If not programmed, the programmable flags default to Empty+7 for PAEAand PAEB, and Full-7 for PAFA and PAFB. The IDT72V801/72V811/72V821/72V831/72V841/72V851 architecture lends itself to many flexible configurations such as: • 2-level priority data buffering • Bidirectional operation • Width expansion • Depth expansion This FIFO is fabricated using IDT's high-performance submicron CMOS technology. .UNCTIONAL BLOCK DIAGRAM WCLKA WENA1 WENA2 DA0 - DA8 LDA OFFSET REGISTER INPUT REGISTER WRITE CONTROL LOGIC RESET LOGIC OUTPUT REGISTER OEA RSA QA0 - QA8 RCLKA RENA1 RENA2 READ CONTROL LOGIC READ POINTER FLAG LOGIC EFA PAEA PAFA FFA 4093 drw 01 WCLKB WENB1 WENB2 DB0 - DB8 LDB OFFSET REGISTER INPUT REGISTER RAM ARRAY 256 x 9, 512 x 9, 1,024 x 9, 2,048 x 9, 4,096 x 9, 8,192 x 9 WRITE CONTROL LOGIC WRITE POINTER RESET LOGIC OUTPUT REGISTER OEB RSB QB0 - QB8 RCLKB RENB1 RENB2 READ CONTROL LOGIC READ POINTER FLAG LOGIC EFB PAFB FFB PAEB WRITE POINTER RAM ARRAY 256 x 9, 512 x 9, 1,024 x 9, 2,048 x 9, 4,096 x 9, 8,192 x 9 |
