Functional Description
The CY7C1329 is a 3.3V, 64K by 32 synchronous-pipelined
cache SRAM designed to support zero wait state secondary
cache with minimal glue logic.
Logic Block Diagram
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. Max-
imum access delay from the clock rise is 4.2 ns (133-MHz
device).
The CY7C1329 supports either the interleaved burst se-
quence used by the Intel Pentium processor 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 con-
trolled by the ADV input. A 2-bit on-chip wraparound burst
counter captures the first address in a burst sequence and
automatically increments the address for the rest of the burst
access.
Byte write operations are qualified with the four Byte Write
Select (BW
[3:0]
) 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

) and an
asynchronous Output Enable (OE) provide for easy bank se-
lection and output three-state control. In order to provide prop-
er data during depth expansion, OE is masked during the first
clock of a read cycle when emerging from a deselected state.
