4-Mbit (128K x 36) Pipelined Sync SRAM
Functional Description
[1]
The CY7C1347F is a 3.3V, 128K by 36 synchronous-pipelined
SRAM designed to support zero-wait-state secondary cache
with minimal glue logic.
CY7C1347F I/O pins can operate at either the 2.5V or the 3.3V
level, the I/O pins are 3.3V tolerant when V
DDQ
= 2.5V.
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 2.6 ns (250-MHz
device)
CY7C1347F supports either the interleaved burst sequence
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 Address Strobe from
Processor (ADSP) or the Address Strobe from Controller
(ADSC) at clock rise. Address advancement through the burst
sequence is controlled 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
[A:D]
) 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
circuitry.
Three synchronous Chip Selects (CE
1
, CE
2
, CE
3
) and an
asynchronous 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 emerging from a deselected
state.
