Functional Description
The CY7C42X1 are high-speed, low-power FIFO memories
with clocked Read and Write interfaces. All are 9 bits wide. The
CY7C42X1 are pin-compatible to IDT722X1. Programmable
features include Almost Full/Almost Empty flags. These FIFOs
provide solutions for a wide variety of data buffering needs,
including high-speed data acquisition, multiprocessor inter-
faces, and communications buffering.
These FIFOs have 9-bit input and output ports that are
controlled by separate clock and enable signals. The input port
is controlled by a free-running clock (WCLK) and two
Write-enable pins (WEN1, WEN2/LD).
When WEN1 is LOW and WEN2/LD is HIGH, data is written
into the FIFO on the rising edge of the WCLK signal. While
WEN1, WEN2/LD is held active, data is continually written into
the FIFO on each WCLK cycle. The output port is controlled in
a similar manner by a free-running Read clock (RCLK) and two
Read-enable pins (REN1, REN2). In addition, the CY7C42X1
has an output enable pin (OE). The Read (RCLK) and Write
(WCLK) clocks may be tied together for single-clock operation
or the two clocks may be run independently for asynchronous
Read/Write applications. Clock frequencies up to 100 MHz are
achievable.
Depth expansion is possible using one enable input for system
control, while the other enable is controlled by expansion logic
to direct the flow of data.
