The CY7C1337 is 3.3V 32K by 32 synchronous-pipelined
cache SRAM designed to support zero wait state secondary
cache with minimal glue logic.
All synchronous inputs pass through input registers controlled
by the rising edge of the clock. All data outputs pass through
output registers controlled by the rising edge of the clock.
Maximum access delay from the clock rise is 5ns (117 MHz
version). A 2-bit on-chip wraparound burst counter captures
the first address in a burst sequence and automatically incre-
ments the address for the rest of the burst access.
The CY7C1337 supports either the interleaved burst se-
quence or a linear burst sequence used by processors such
as the PowerPC. The burst sequence is selected through the
MODE pin. Accesses can be initiated by asserting either the
processor address strobe (ADSP) or the controller address
strobe (ADSC) at clock rise. Address advancement through
the burst sequence is controlled by the ADV input.
Byte write operations are qualified with the four Byte Write
Select (BW
[0-3]
) inputs. A Global Write Enable (GW) overrides
all byte write inputs and writes data to all four bytes. All writes
are conducted with on-chip synchronous self-timed write cir-
cuitry.
Three synchronous chip selects (CE
1
, CE
2
, CE
3
) and an asyn-
chronous output enable (OE) provide for easy bank selection
and output three-state control. In order to provide proper data
during depth expansion, OE is masked during the first clock of
a read cycle when going from a deselected to a selected state.
