DESCRIPTION:
The FCT162701T/AT is an 18-bit Read/Write buffer with
a four deep FIFO and a read-back latch. It can be used as
a read/write buffer between a CPU and memory or to
interface a high-speed bus and a slow peripheral. The A-
to-B (write) path has a four deep FIFO for pipelined opera-
tions. The FIFO can be reset and a FIFO full condition is
indicated by the full flag (
FF
). The B-to-A (read) path has a
latch. A HIGH on LE, allows data to flow transparently from
B-to-A. A LOW on LE allows the data to be latched on the
falling edge of LE.
The FCT162701T/AT has a balanced output drive with
series termination. This provides low ground bounce,
minimal undershoot and controlled output edge rates.
