CY7C0832BV-133AI Code Extract

CY7C0832BV-133AI Code Extract, cypress MCU decryption, cypress chip crack, cypress PCB clone .
The FLEx18? family includes 2-Mbit, 4-Mbit, and 9-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. 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).
The CY7C0833V device in this family has limited features. See
Address Counter and Mask Register Operations on page 7 for
details.
