DESCRIPTION:
The IDT72132/72142 are high-speed, low-power serial-to-
parallel FIFOs. These FIFOs are ideally suited to serial
communications applications, tape/disk controllers, and local
area networks (LANs). The IDT72132/72142 can be config-
ured with the IDTs parallel-to-serial FIFOs (IDT72131/72141)
for bidirectional serial data buffering.
The FIFO has a serial input port and a 9-bit parallel output
port. Wider and deeper serial-to-parallel data buffers can be
built using multiple IDT72132/72142 chips. IDTs unique
Flexshift serial expansion logic (SIX,
NW
) makes width
expansion possible with no additional components. These
FIFOs will expand to a variety of word widths including 8, 9, 16,
and 32 bits. The IDT72132/142 can also be directly connected
for depth expansion.
Five flags are provided to monitor the FIFO. The full and
empty flags prevent any FIFO data overflow or underflow
conditions. The Almost-Full (7/8), Half-Full, and Almost Empty
(1/8) flags signal memory utilization within the FIFO.
The IDT72132/72142 is fabricated using IDTs high-speed
submicron CMOS technology.
