CY7C1339F
4-Mbit (128K x 32) Pipelined Sync SRAM
Functional Description[1]
Features
• Registered inputs and outputs for pipelined operation
• 128K × 32 common I/O architecture
• 3.3V core power supply
• 2.5V / 3.3V I/O operation
• Fast clock-to-output times
— 2.6 ns (for 250-MHz device)
— 2.6 ns (for 225-MHz device)
— 2.8 ns (for 200-MHz device)
The CY7C1339F SRAM integrates 131,072 x 32 SRAM cells
with advanced synchronous peripheral circuitry and a two-bit
counter for internal burst operation. All synchronous inputs are
gated by registers controlled by a positive-edge-triggered
Clock Input (CLK). The synchronous inputs include all
addresses, all data inputs, address-pipelining Chip Enable
(CE1), depth-expansion Chip Enables (CE2 and CE3), Burst
Control inputs (ADSC, ADSP, and ADV), Write Enables
(BW[A:D], and BWE), and Global Write (GW). Asynchronous
inputs include the Output Enable (OE) and the ZZ pin.
Addresses and chip enables are registered at rising edge of
clock when either Address Strobe Processor (ADSP) or
Address Strobe Controller (ADSC) are active. Subsequent
burst addresses can be internally generated as controlled by
the Advance pin (ADV).
— 3.5 ns (for 166-MHz device)
— 4.0 ns (for 133-MHz device)
— 4.5 ns (for 100-MHz device)
• Provide high-performance 3-1-1-1 access rate
• User-selectable burst counter supporting Intel
Pentium interleaved or linear burst sequences
• Separate processor and controller address strobes
• Synchronous self-timed writes
• Asynchronous output enable
• Offered in JEDEC-standard 100-pin TQFP and 119-ball
BGA packages
• “ZZ” Sleep Mode Option
Address, data inputs, and write controls are registered on-chip
to initiate a self-timed Write cycle.This part supports Byte Write
operations (see Pin Descriptions and Truth Table for further
details). Write cycles can be one to four bytes wide as
controlled by the byte write control inputs. GW when active
LOW causes all bytes to be written.
The CY7C1339F operates from a +3.3V core power supply
while all outputs may operate with either a +2.5 or +3.3V
supply. All inputs and outputs are JEDEC-standard
JESD8-5-compatible.

Functional Overview
Single Write Accesses Initiated by ADSP
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 3.5 ns
(166-MHz device).
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.
The CY7C1339F 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.
Byte Write operations are qualified with the Byte Write Enable
(BWE) and 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 simplified with on-chip
synchronous self-timed Write circuitry.
Three synchronous Chip Selects (CE1, CE2, CE3) and an
asynchronous Output Enable (OE) provide for easy bank
selection and output three-state control. ADSP is ignored if
CE1 is HIGH.
Single Read Accesses
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 3.5 ns (166-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 three-stated during the first cycle of the access. After
the first cycle of the access, the outputs are controlled by the
OE signal. Consecutive single Read cycles are supported.
Once the SRAM is deselected at clock rise by the chip select
and either ADSP or ADSC signals, its output will three-state
immediately.
Document #: 38-05217 Rev. *C
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 corresponding address location in the memory array. If GW is HIGH,
then the Write operation is controlled by BWE and BW[A:D]
signals. The CY7C1339F 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.
Because the CY7C1339F is a common I/O device, the Output
Enable (OE) must be deserted HIGH before presenting data
to the DQs inputs. Doing so will three-state the output drivers.
As a safety precaution, DQs are automatically three-stated
whenever a Write cycle is detected, regardless of the state of
OE.
Single Write Accesses Initiated by ADSC
ADSC Write accesses are initiated when the following conditions are satisfied: (1) ADSC is asserted LOW, (2) ADSP is
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.
Because the CY7C1339F is a common I/O device, the Output
Enable (OE) must be deserted HIGH before presenting data
to the DQs inputs. Doing so will three-state the output drivers.
As a safety precaution, DQs are automatically three-stated
whenever a Write cycle is detected, regardless of the state of
OE.

Burst Sequences
Interleaved Burst Address Table
(MODE = Floating or VDD)
The CY7C1339F 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 specifically 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.
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.

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.

Notes:
2. X = “Don't Care.” H = Logic HIGH, L = Logic LOW.
3. WRITE = L when any one or more Byte Write enable signals (BWA, BWB, BWC, BWD) and BWE = L or GW= L. WRITE = H when all Byte write enable signals
(BWA, BWB, BWC, BWD), BWE, GW = H.
4. The DQ pins are controlled by the current cycle and the OE signal. OE is asynchronous and is not sampled with the clock.
5. CE1, CE2, and CE3 are available only in the TQFP package. BGA package has only 2 chip selects CE1 and CE2.
6. The SRAM always initiates a read cycle when ADSP is asserted, regardless of the state of GW, BWE, or BW[A: D]. Writes may occur only on subsequent clocks
after the ADSP or with the assertion of ADSC. As a result, OE must be driven HIGH prior to the start of the write cycle to allow the outputs to three-state. OE is
a don't care for the remainder of the write cycle
7. OE is asynchronous and is not sampled with the clock rise. It is masked internally during write cycles. During a read cycle all data bits are three-state when OE
is inactive or when the device is deselected, and all data bits behave as output when OE is active (LOW).

Notes:
12. This part has a voltage regulator internally; tPOWER is the time that the power needs to be supplied above VDD(minimum) initially before a read or write operation
can be initiated.
13. tCHZ, tCLZ,tOELZ, and tOEHZ are specified with AC test conditions shown in part (b) of AC Test Loads. Transition is measured ± 200 mV from steady-state voltage.
14. At any given voltage and temperature, tOEHZ is less than tOELZ and tCHZ is less than tCLZ to eliminate bus contention between SRAMs when sharing the same
data bus. These specifications do not imply a bus contention condition, but reflect parameters guaranteed over worst case user conditions. Device is designed
to achieve High-Z prior to Low-Z under the same system conditions
15. This parameter is sampled and not 100% tested.
16. Timing reference level is 1.5V when VDDQ = 3.3V and is 1.25V when VDDQ = 2.5V.
17. Test conditions shown in (a) of AC Test Loads unless otherwise noted.
