Read/Modify/Write sequences, which can be reduced to
simple Byte Write operations.
Because the CY7C1354B and CY7C1356B are common I/O
devices, data should not be driven into the device while the
outputs are active. The Output Enable (OE) can be deasserted
HIGH
(DQ
CY7C1356B) inputs. Doing so will three-state the output
drivers. As a safety precaution, DQ
DQP
CY7C1356B) are automatically three-stated during the data
portion of a write cycle, regardless of the state of OE.
Burst Write Accesses
The CY7C1354B/56B has an on-chip burst counter that allows
the user the ability to supply a single address and conduct up
to four WRITE operations without reasserting the address
inputs. ADV/LD must be driven LOW in order to load the initial
address, as described in the Single Write Access section
above. When ADV/LD is driven HIGH on the subsequent clock
rise, the chip enables (CE
ignored and the burst counter is incremented. The correct BW
(BW
must be driven in each cycle of the burst write in order to write
the correct bytes of data.
Sleep Mode
The ZZ input pin is an asynchronous input. Asserting ZZ
places the SRAM in a power conservation “sleep” mode. Two
clock cycles are required to enter into or exit from this “sleep”
