Functional Description
The FLEx36 family includes 1M, 2M, 4M and 9M pipelined,
synchronous, true dual-port static RAMs that are high-speed,
low-power 3.3V CMOS. Two ports are provided, permitting
independent, simultaneous access to any location in memory.
The result of writing to the same location by more than one port
at the same time is undefined. Registers on control, address,
and data lines allow for minimal set-up and hold time.
During a Read operation, data is registered for decreased
cycle time. Each port contains a burst counter on the input
address register. After externally loading the counter with the
initial address, the counter will increment the address inter-
nally (more details to follow). The internal Write pulse width is
independent of the duration of the R/W input signal. The
internal Write pulse is self-timed to allow the shortest possible
cycle times.
A HIGH on CE0 or LOW on CE1 for one clock cycle will power
down the internal circuitry to reduce the static power
consumption. One cycle with chip enables asserted is required
to reactivate the outputs.
Additional features include: readback of burst-counter internal
address value on address lines, counter-mask registers to
control the counter wrap-around, counter interrupt (CNTINT)
flags, readback of mask register value on address lines,
retransmit functionality, interrupt flags for message passing,
JTAG for boundary scan, and asynchronous Master Reset
(MRST).
The CY7C0853 device in this family has limited features.
