Addresses and chip enables are registered at the rising edge of
the 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 Definitions" on page 5 and "Truth Table" on
page 8 for further details). Write cycles can be one to two or four
bytes wide as controlled by the byte write control inputs. GW
when active LOW causes all bytes to be written.
The CY7C1480V33 operates from a +3.3 V core power supply
while all outputs may operate with either a +2.5 or +3.3 V supply.
All inputs and outputs are JEDEC standard 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. Maximum
access delay from the clock rise (tCO) is 3.0 ns (200 MHz device).
The CY7C1480V33 supports secondary cache in systems using
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 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.
Three synchronous Chip Selects (CE1, CE2, CE3) and an
asynchronous Output Enable (OE) provide easy bank selection
and output tri-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 deasserted 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
Document Number: 38-05283 Rev. *N
propagate through the output register and onto the data bus
within 3.0 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 signal. Consecutive single
read cycles are supported. After the SRAM is deselected at clock
rise by the chip select and either ADSP or ADSC signals, its
output tri-states immediately.
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) 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 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 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 BWX
signals.
The CY7C1480V33 provides byte write capability that is
described in the "Truth Table for Read/Write" on page 9.
Asserting the Byte Write Enable input (BWE) with the selected
Byte Write (BWX) 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 CY7C1480V33 is a common I/O device, the Output
Enable (OE) must be deasserted 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.

CY7C1480V33
Single Write Accesses Initiated by ADSC
Sleep Mode
ADSC Write accesses are initiated when the following conditions
are satisfied: (1) ADSC is asserted LOW, (2) ADSP is deasserted
HIGH, (3) CE1, CE2, CE3 are all 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 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.
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 before entering the “sleep” mode. CE1, CE2,
CE3, ADSP, and ADSC must remain inactive for the duration of
tZZREC after the ZZ input returns LOW.
Interleaved Burst Address Table
(MODE = Floating or VDD)
Because CY7C1480V33 is a common I/O device, the Output
Enable (OE) must be deasserted 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.
Burst Sequences
The CY7C1480V33 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.

Notes
4. X = “Don't Care.” H = Logic HIGH, L = Logic LOW.
5. 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.
6. The DQ pins are controlled by the current cycle and the OE signal. OE is asynchronous and is not sampled with the clock.
7. 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 before the start of the write cycle to allow the outputs to tri-state. OE is a “don't care”
for the remainder of the write cycle.
8. 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 Tri-State when OE is
inactive or when the device is deselected, and all data bits behave as output when OE is active (LOW).

13. Timing reference level is 1.5 V when VDDQ = 3.3 V and is 1.25 V when VDDQ = 2.5 V.
14. Test conditions shown in (a) of Figure 2 on page 12 unless otherwise noted.
15. This part has an internal voltage regulator; tPOWER is the time that the power needs to be supplied above VDD(minimum) initially before a read or write operation can
be initiated.
16. tCHZ, tCLZ, tOELZ, and tOEHZ are specified with AC test conditions shown in part (b) of Figure 2 on page 12. Transition is measured ±200 mV from steady-state voltage.
17. At any possible 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 before Low-Z under the same system conditions.
18. This parameter is sampled and not 100% tested.

The following table defines the errata applicable to available Ram9 72Mb Sync/NoBL family devices.
Item
1.
Issues
ZZ Pin
Description
Device
Fix Status
When asserted HIGH, the ZZ pin places device in
a “sleep” condition with data integrity
preserved.The ZZ pin currently does not have an
internal pull-down resistor and hence cannot be
left floating externally by the user during normal
mode of operation.
72M-Ram9 (90nm)
For the 72M Ram9 (90 nm)
devices, this issue was fixed in
the new revision. Please
contact your local sales rep for
availability.
1. ZZ Pin Issue
■
PROBLEM DEFINITION
The problem occurs only when the device is operated in the normal mode with ZZ pin left floating. The ZZ pin on the SRAM
device does not have an internal pull-down resistor. Switching noise in the system may cause the SRAM to recognize a HIGH
on the ZZ input, which may cause the SRAM to enter sleep mode. This could result in incorrect or undesirable operation of the
SRAM.
■
TRIGGER CONDITIONS
Device operated with ZZ pin left floating.
■
SCOPE OF IMPACT
When the ZZ pin is left floating, the device delivers incorrect data.
■
WORKAROUND
Tie the ZZ pin externally to ground.
■
FIX STATUS
Fix was done for the 72Mb RAM9 Synchronous SRAMs and 72M RAM9 NoBL SRAMs devices. Fixed devices have a new
revision. The following table lists the devices affected and the new revision after the fix.
