description
The SN74ACT3641 is a high-speed, low-power, CMOS clocked FIFO memory. It supports clock frequencies
up to 67 MHz and has read access times as fast as 12 ns. The 1024
× 36 dual-port SRAM FIFO buffers data
from port A to port B. The FIFO memory has retransmit capability, which allows previously read data to be
accessed again. The FIFO has flags to indicate empty and full conditions and two programmable flags (almost
full and almost empty) to indicate when a selected number of words is stored in memory. Communication
between each port takes place with two 36-bit mailbox registers. Each mailbox register has a flag to signal when
new mail has been stored. Two or more devices are used in parallel to create wider datapaths. Expansion is
also possible in word depth.
The SN74ACT3641 is a clocked FIFO, which means each port employs a synchronous interface. All data
transfers through a port are gated to the low-to-high transition of a continuous (free-running) port clock by enable
signals. The continuous clocks for each port are independent of one another and can be asynchronous or
coincident. The enables for each port are arranged to provide a simple interface between microprocessors
and/or buses with synchronous control.
The input-ready (IR) flag and almost-full (AF) flag of the FIFO are two-stage synchronized to CLKA. The
output-ready (OR) flag and almost-empty (AE) flag of the FIFO are two-stage synchronized to CLKB. Offset
values for the AF and AE flags of the FIFO can be programmed from port A or through a serial input.
The SN74ACT3641 is characterized for operation from 0
°C to 70°C.
