The CY7C1386KV33/CY7C1387KV33 SRAM integrates
512K × 36/1M × 18 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 (BWX, 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).
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 Configurations on page 5 and Truth Table on
page 9 for further details). Write cycles can be one to four bytes
wide as controlled by the byte write control inputs. GW active
LOW causes all bytes to be written. This device incorporates an
additional pipelined enable register which delays turning off the
output buffers an additional cycle when a deselect is
executed.This feature allows depth expansion without penalizing
system performance.
The CY7C1386KV33/CY7C1387KV33 operates from a +3.3 V
core power supply while all outputs operate with a +3.3 V or
+2.5 V supply. All inputs and outputs are JEDEC-standard and
JESD8-5-compatible.

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.
The CY7C1386KV33/CY7C1387KV33 supports secondary
cache in systems using either a linear or interleaved burst
sequence. The linear burst sequence is suited for processors
that use 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 (BWX) 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.
Synchronous chip selects CE1, CE2, CE3 and an asynchronous
output enable (OE) provide for easy bank selection and output
tristate 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)
chip selects are all asserted active, and (3) the write signals (GW,
BWE) are all deasserted HIGH. ADSP is ignored if CE1 is HIGH.
The address presented to the address inputs is stored into the
address advancement logic and the address register while being
presented to the memory core. 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 tCO 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 tristated 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.
Document Number: 001-97893 Rev. *E
The CY7C1386KV33/CY7C1387KV33 is a double cycle
deselect part. After the SRAM is deselected at clock rise by the
chip select and either ADSP or ADSC signals, its output tristates
immediately after the next clock rise.
Single Write Accesses Initiated by ADSP
This access is initiated when both of the following conditions are
satisfied at clock rise: (1) ADSP is asserted LOW and (2) chip
select is asserted active. The address presented is loaded into
the address register and the address advancement logic while
being delivered to the memory core. The write signals (GW,
BWE, and BWX) and ADV inputs are ignored during this first
cycle.
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 DQx inputs is written into the
corresponding address location in the memory core. If GW is
HIGH, the write operation is controlled by BWE and BWX signals.
The CY7C1386KV33/CY7C1387KV33 provides byte write
capability that is described in the write cycle description table.
Asserting the byte write enable input (BWE) with the selected
byte write input, selectively writes to the desired bytes. Bytes not
selected during a byte write operation remains unaltered. A
synchronous self timed write mechanism has been provided to
simplify the write operations.
The CY7C1386KV33/CY7C1387KV33 is a common I/O device,
the output enable (OE) must be deasserted HIGH before
presenting data to the DQ inputs. This tristates the output drivers.
As a safety precaution, DQ are automatically tristated 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 deasserted
HIGH, (3) chip select is asserted active, and (4) the appropriate
combination of the write inputs (GW, BWE, and BWX) 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 is loaded into the address register and
the address advancement logic while being delivered to the
memory core. The ADV input is ignored during this cycle. If a
global write is conducted, the data presented to the DQX 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 remains
unaltered. A synchronous self timed write mechanism has been
provided to simplify the write operations.
deselected prior to entering the sleep mode. CEs, ADSP, and
ADSC must remain inactive for the duration of tZZREC after the
ZZ input returns LOW.
The CY7C1386KV33/CY7C1387KV33 is a common I/O device,
the output enable (OE) must be deasserted HIGH before
presenting data to the DQX inputs. This tristates the output
drivers. As a safety precaution, DQX are automatically tristated
whenever a write cycle is detected, regardless of the state of OE.

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

Notes
1. X = Do not care, H = Logic HIGH, L = Logic LOW.
2. WRITE = L when any one or more byte write enable signals, and BWE = L or GW = L. WRITE = H when all byte write enable signals, BWE, GW = H.
3. The DQ pins are controlled by the current cycle and the OE signal. OE is asynchronous and is not sampled with the clock.
4. The SRAM always initiates a read cycle when ADSP is asserted, regardless of the state of GW, BWE, or BWX. 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 tristate. OE is a don't care
for the remainder of the write cycle.
5. 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 tristate when OE is inactive
or when the device is deselected, and all data bits behave as output when OE is active (LOW).

Notes
10. Timing reference level is 1.5 V when VDDQ = 3.3 V and is 1.25 V when VDDQ = 2.5 V.
11. Test conditions shown in (a) of Figure 2 on page 13 unless otherwise noted.
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 (b) of Figure 2 on page 13. Transition is measured ±200 mV from steady-state voltage.
14. At any 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.
