all four bytes. All writes are simplified with on-chip

Functional Overview
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 (tCO) is 2.6 ns
(250-MHz device).
Three synchronous Chip Selects (CE1, CE2, CE3) and an
asynchronous Output Enable (OE) provide for easy bank
selection and output tri-state control. ADSP is ignored if CE1
is HIGH.
Single Read Accesses
The CY7C1339G supports secondary cache in systems
utilizing either a linear or interleaved burst sequence. The
interleaved burst order supports Pentium and i486™
processors. The linear burst sequence is suited for processors
that utilize a linear burst sequence. The burst order is user
selectable, and is determined by sampling the MODE input.
Accesses can be initiated with either the Processor Address
Strobe (ADSP) or the Controller Address Strobe (ADSC).
Address advancement through the burst sequence is
controlled by the ADV input. A two-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.
This access is initiated when the following conditions are
satisfied at clock rise: (1) ADSP or ADSC is asserted LOW, (2)
CE1, CE2, CE3 are all asserted active, and (3) the Write
signals (GW, BWE) are all deserted HIGH. ADSP is ignored if
CE1 is HIGH. The address presented to the address inputs (A)
is stored into the address advancement logic and the Address
Register while being presented to the memory array. The
corresponding data is allowed to propagate to the input of the
Output Registers. At the rising edge of the next clock the data
is allowed to propagate through the output register and onto
the data bus within 2.6 ns (250-MHz device) if OE is active
LOW. The only exception occurs when the SRAM is emerging
from a deselected state to a selected state, its outputs are
always tri-stated during the first cycle of the access. After the
first cycle of the access, the outputs are controlled by the OE
Byte Write operations are qualified with the Byte Write Enable

to the DQs inputs. Doing so will tri-state the output drivers. As
a safety precaution, DQs are automatically tri-stated whenever
a Write cycle is detected, regardless of the state of OE.
Burst Sequences
Single Write Accesses Initiated by ADSP
The CY7C1339G provides a two-bit wraparound counter, fed
by A1, A0, that implements either an interleaved or linear burst
sequence. The interleaved burst sequence is designed specif-
ically to support Intel Pentium applications. The linear burst
sequence is designed to support processors that follow a
linear burst sequence. The burst sequence is user selectable
through the MODE input.
This access is initiated when both of the following conditions
are satisfied at clock rise: (1) ADSP is asserted LOW, and
(2) CE1, CE2, CE3 are all asserted active. The address
presented to A is loaded into the address register and the
address advancement logic while being delivered to the
memory array. The Write signals (GW, BWE, and BW[A:D]) and
ADV inputs are ignored during this first cycle.
Asserting ADV LOW at clock rise will automatically increment
the burst counter to the next address in the burst sequence.
Both Read and Write burst operations are supported.
ADSP-triggered Write accesses require two clock cycles to
complete. If GW is asserted LOW on the second clock rise, the
data presented to the DQs inputs is written into the corre-
sponding address location in the memory array. If GW is HIGH,
then the Write operation is controlled by BWE and BW[A:D]
signals. The CY7C1339G provides Byte Write capability that
is described in the Write Cycle Descriptions table. Asserting
the Byte Write Enable input (BWE) with the selected Byte
Write (BW[A:D]) input, will selectively write to only the desired
bytes. Bytes not selected during a Byte Write operation will
remain unaltered. A synchronous self-timed Write mechanism
has been provided to simplify the Write operations.
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”
mode. While in this mode, data integrity is guaranteed.
Accesses pending when entering the “sleep” mode are not
considered valid nor is the completion of the operation
guaranteed. The device must be deselected prior to entering
the “sleep” mode. CE1, CE2, CE3, ADSP, and ADSC must
remain inactive for the duration of tZZREC after the ZZ input
returns LOW.
Because the CY7C1339G is a common I/O device, the Output
Enable (OE) must be deserted HIGH before presenting data
to the DQs inputs. Doing so will tri-state the output drivers. As
a safety precaution, DQs are automatically tri-stated whenever
a Write cycle is detected, regardless of the state of OE.

ADSC Write accesses are initiated when the following condi-

deserted HIGH, (3) CE1, CE2, CE3 are all asserted active, and
(4) the appropriate combination of the Write inputs (GW, BWE,
and BW[A:D]) are asserted active to conduct a Write to the
desired byte(s). ADSC-triggered Write accesses require a
single clock cycle to complete. The address presented to A is
loaded into the address register and the address
advancement logic while being delivered to the memory array.
The ADV input is ignored during this cycle. If a global Write is
conducted, the data presented to the DQs is written into the
corresponding address location in the memory core. If a Byte
Write is conducted, only the selected bytes are written. Bytes
not selected during a Byte Write operation will remain
unaltered. A synchronous self-timed Write mechanism has
been provided to simplify the Write operations.
