DESCRIPTION:
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 con-
nected 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 inter-
nal flags can be assigned to any of four external flag pins
(FLG
A
-FLG
D
) through one Configuration Register.
Port B has parity, reread/rewrite and DMA functions. Par-
ity generation and checking can be done by the BiFIFO on
data passing through Port B. The Reread and Rewrite con-
