BIDIRECTIONAL FIRST-IN FIRST-OUT MEMORY
MILITARY AND COMMERCIAL TEMPERATURE RANGES
When either of the internal FIFOs are accessed, 18 bits of
data are transferred across Port A. Since the bypass path is
only 9 bits wide, the least significant byte (D
A0
-D
A7,
D
A16
) is
used on Port A. All of the registers are 16 bits wide which
means only the data bits (D
A0
-D
A15
) are passed by Port A.
Bypass Path
The bypass path acts as a bidirectional bus transceiver
directly between Port A and Port B. The direct connection
requires that the Port A interface pins are inputs and the Port
B interface pins are outputs. The bypass path is 9 bits wide in
an 18- to 18-bit configuration or 18 bits wide in a 36- to 36-
bit configuration.
During bypass operations, the BiFIFOs must be pro-
grammed into peripheral interface mode. Bit 10 of Configura-
tion Register 5 (see Table 10) is set to
1
for peripheral
interface mode.
Command Register
Ten registers are accessible through Port A, a Command
Register, a Status Register, and eight Configuration
Registers.
Peripheral Interface Mode
If Port B is connected to a peripheral controller, all
BiFIFOs in the configuration must be programmed in peri-
pheral interface mode. In this mode, all the Port B interface
pins are all outputs. To assure fixed high states for
R
B
and
W
B
before they are programmed into an output, these two
pins should be pulled up to V
CC
with 10K resistors. Of
course, only one set of Port B interface pins should be used
to control a single peripheral device, while the other interface
pins are all ignored. Figure 2 shows a BiFIFO configuration
connected to a peripheral.
Port A Interface
The BiFIFO is straightforward to use in microprocessor-
based systems because each BiFIFO port has a standard
microprocessor control set. Port A has access to six re-
sources: the A
→
B FIFO, the B
→
A FIFO, the 9-bit direct data
bus (bypass path), the configuration registers, status and
command registers. The Port A Address and Read/Write
pins determine the resource being accessed as shown in
Table 1. Data Strobe is used to move data in and out of the
BiFIFO.
