NOTE: The IDT72510/72520 have been obsoleted and the last time buy will on 01/29/2003. These devices should not be used in new designs. FEATURES:
The IDT72510 and IDT72520 are highly integrated first-in, first-out memories that enhance processor-to-processor and processor-to-peripheral communications. IDT BiFIFOs integrate two side-by-side memory arrays for data transfers in two directions. The BiFIFOs have two ports, A and B, that both have standard microprocessor interfaces. All BiFIFO operations are controlled from the 18-bit wide Port A. The BiFIFOs incorporate bus matching logic to convert the 18-bit wide memory data paths to the 9-bit wide Port B data bus. The BiFIFOs have a bypass path that allows the device connected to Port A to pass messages directly to the Port B device. Ten registers are accessible through Port A, a Command Register, a Status Register, and eight Configuration Registers. The IDT BiFIFOs have programmable flags. Each FIFO memory array has four internal flags, Empty, Almost-Empty, Almost-Full and Full, for a total of eight internal flags. The Almost-Empty and Almost-Full flag offsets can be set to any depth through the Configuration Registers. These eight internal flags can be assigned to any of four external flag pins (FLGA-FLGD) through one Configuration Register. Port B has parity, reread/rewrite and DMA functions. Parity generation and checking can be done by the BiFIFO on data passing through Port B. The Reread and Rewrite controls will read or write Port B data blocks multiple times. The BiFIFOs have three pins, REQ, ACK and CLK, to control DMA transfers from Port B devices.

Data A Parity A Chip Select A Data Strobe A Read/Write A
Data inputs and outputs for 16 bits of the 18-bit Port A bus. DA16 is the parity bit for DA17 is the parity bit for DA8-DA15. DA16 and DA17 can be used as two extra data bits if the parity generate function is disabled. Port A is accessed when Chip Select A is LOW. Data is written into Port A on the rising edge of Data Strobe when Chip Select is LOW. Data is read out of Port A on the falling edge of Data Strobe when Chip Select A is LOW. This pin controls the read or write direction of Port A. When CSA is LOW and R/WA is HIGH, data is read from Port A on the falling edge of DSA. When CSA is LOW and R/WA is LOW, data is written into Port A on the rising edge DS A. When Chip Select A is asserted, A0, A1, and Read/Write A are used to select one of six internal resources. Data inputs and outputs for 8 bits of the 9-bit Port B bus. DB8 is the parity bit for DB0-DB7. DB8 can be used as a data bit if the parity generate function is disabled. If Port B is programmed to processor mode, this pin functions as an input. If Port B is programmed to peripheral mode this pin functions as an output. This pin can function as part of an Intel-style interface (RB) or as part of a Motorola-style interface (DSB). As an Intel-style interface, data is read from Port on a falling edge of RB. As a Motorola-style interface, data is read on the falling edge of DSB or written on the rising edge of DSB through Port B. The Default is Intelstyle processor mode (RB as an input). If Port B is programmed to processor mode, this pin functions as an input. If Port B is programmed to peripheral mode this pin functions as an output. This pin can function as part of an Intel-style interface (WB) or as part of a Motorola-style interface (R/WB). As an Intel style interface, data is written to Port on a rising edge of WB. As a Motorola-style interface, data is read (R/WB = HIGH) or written (R/WB = LOW) to Port B in conjunction with a Data Strobe B falling or rising edge. The Default is Intel-style processor mode (WB as input). Loads A-to-B FIFO Read Pointer with the value of the Reread Pointer when LOW. Loads B-to-A FIFO Write Pointer with the value of the Rewrite Pointer when LOW. Loads the Reread Pointer with the value of the A-to-B FIFO Read Pointer when HIGH. This signal is accessible through the Command Register. Loads the Rewrite Pointer with the value of the B-to-A FIFO Write Pointer when HIGH. This signal is accessible through the Command Register. When Port B is programmed in peripheral mode, asserting this pin begins a data transfer. Request can be programmed either active HIGH or active LOW. When Port B is programmed in peripheral mode, Acknowledge is asserted in response to a Request signal. This confirms that a data transfer may begin. Acknowledge can be programmed either active HIGH or active LOW. This pin is used to generate timing for ACK, RB, WB, DSB and R/WB when Port is in the peripheral mode. These four outputs pins can be assigned to any one of the eight internal flags in the BiFIFO. Each of the two internal FIFOs (A-to-B and B-to-A) has four internal flags: Empty, Almost-Empty, Almost-Full, and Full. If parity checking is enabled, the FLGA pin can also be assigned as a parity error output. A LOW on this pin will perform a reset of all BiFIFO functions. Software reset can be achieved through command register. There are two +5V power pins on all four devices. There are four ground pinsReread Rewrite Load Reread Load Rewrite Request Acknowledge Clock Flags
