Functional Description
The FLEx36™ family includes 2-Mbit pipelined, synchronous,
true dual-port static RAMs that are high speed, low power 3.3 V
CMOS. Two ports are provided, permitting independent,
simultaneous access to any location in memory. A particular port
can write to a certain location while another port is reading that
location. 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 setup 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 increments the address internally (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 powers 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).
Seamless Migration to Next-Generation Dual-Port
Family
Cypress offers a migration path for all devices in this family to the
next-generation devices in the Dual-Port family with a compatible
footprint. Please contact Cypress Sales for more details.
