The CY7C1350G is equipped with the advanced No Bus Latency™ (NoBL™) logic required to enable consecutive read/write operations with data being transferred on every clock cycle. This feature dramatically improves the throughput of the SRAM, especially in systems that require frequent write/read transitions. 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 clock input is qualified by the clock enable (CEN) signal, which, when deasserted, suspends operation and extends the previous clock cycle. Maximum access delay from the clock rise is 2.8 ns (200-MHz device). Write operations are controlled by the four byte write select (BW[A:D]) and a write enable (WE) input. All writes are conducted with on-chip synchronous self-timed write circuitry. Three synchronous chip enables (CE1, CE2, CE3) and an asynchronous output enable (OE) provide for easy bank selection and output tristate control. In order to avoid bus contention, the output drivers are synchronously tri-stated during the data portion of a write sequence.

Sampled at the rising edge of synchronous the CLK. A[1:0] are fed to the two-bit burst counter. BW[A:D] InputByte write inputs, active LOW. Qualified with WE to conduct writes to the SRAM. Sampled on the rising synchronous edge of CLK. WE InputWrite enable input, active LOW. Sampled on the rising edge of CLK if CEN is active LOW. This signal synchronous must be asserted LOW to initiate a write sequence. ADV/LD InputAdvance/load input. Used to advance the on-chip address counter or load a new address. When HIGH synchronous (and CEN is asserted LOW) the internal burst counter is advanced. When LOW, a new address can be loaded into the device for an access. After being deselected, ADV/LD should be driven LOW in order to load a new address. CLK Input-clock Clock input. Used to capture all synchronous inputs to the device. CLK is qualified with CEN. CLK is only recognized if CEN is active LOW. CE1 InputChip enable 1 input, active LOW. Sampled on the rising edge of CLK. Used in conjunction with CE2 synchronous and CE3 to select/deselect the device. CE2 InputChip enable 2 input, active HIGH. Sampled on the rising edge of CLK. Used in conjunction with CE1 synchronous and CE3 to select/deselect the device. CE3 InputChip enable 3 input, active LOW. Sampled on the rising edge of CLK. Used in conjunction with CE1 synchronous and CE2 to select/deselect the device. OE InputOutput enable, asynchronous input, active LOW. Combined with the synchronous logic block inside asynchronous the device to control the direction of the I/O pins. When LOW, the I/O pins are allowed to behave as outputs. When deasserted HIGH, I/O pins are tri-stated, and act as input data pins. OE is masked during the data portion of a write sequence, during the first clock when emerging from a deselected state, when the device has been deselected. CEN InputClock enable input, active LOW. When asserted LOW the Clock signal is recognized by the SRAM. synchronous When deasserted HIGH the clock signal is masked. Since deasserting CEN does not deselect the device, CEN can be used to extend the previous cycle when required. ZZ InputZZ “sleep” input. This active HIGH input places the device in a non-time critical “sleep” condition with asynchronous data integrity preserved. During normal operation, this pin has to be low or left floating. ZZ pin has an internal pull-down. DQs I/OBidirectional data I/O lines. As inputs, they feed into an on-chip data register that is triggered by the synchronous rising edge of CLK. As outputs, they deliver the data contained in the memory location specified by the address during the clock rise of the read cycle. The direction of the pins is controlled by OE and the internal control logic. When OE is asserted LOW, the pins can behave as outputs. When HIGH, DQs and DQPX are placed in a tristate condition. The outputs are automatically tri-stated during the data portion of a write sequence, during the first clock when emerging from a deselected state, and when the device is deselected, regardless of the state of OE. DQP[A:D] I/OBidirectional data parity I/O lines. Functionally, these signals are identical to DQs. During write synchronous sequences, DQP[A:D] is controlled by BW[A:D] correspondingly. MODE VDD VDDQ Input strap pin Mode input. Selects the burst order of the device. When tied to GND selects linear burst sequence. When tied to VDD or left floating selects interleaved burst sequence. Power supply Power supply inputs to the core of the device. I/O power supply VSS Ground NC – Power supply for the I/O circuitry. Ground for the device. No Connects. Not internally connected to the die. 9M, 18M, 36M, 72M, 144M and 288M are address expansion pins in this device and will be used as address pins in their respective densities. Document Number: 38-05524 Rev. *L Page 5 of 21 CY7C1350G Functional Overview a burst cycle. Therefore, the type of access (read or write) is maintained throughout the burst sequence. The CY7C1350G is a synchronous-pipelined burst SRAM designed specifically to eliminate wait states during write/read transitions. All synchronous inputs pass through input registers controlled by the rising edge of the clock. The clock signal is qualified with the clock enable input signal (CEN). If CEN is HIGH, the clock signal is not recognized and all internal states are maintained. All synchronous operations are qualified with CEN. All data outputs pass through output registers controlled by the rising edge of the clock. Maximum access delay from the clock rise (tCO) is 2.8 ns (200-MHz device). Accesses can be initiated by asserting all three chip enables (CE1, CE2, CE3) active at the rising edge of the clock. If clock enable (CEN) is active LOW and ADV/LD is asserted LOW, the address presented to the device will be latched. The access can either be a read or write operation, depending on the status of the write enable (WE). BW[A:D] can be used to conduct byte write operations. Write operations are qualified by the write enable (WE). All writes are simplified with on-chip synchronous self-timed write circuitry. Three synchronous chip enables (CE1, CE2, CE3) and an asynchronous output enable (OE) simplify depth expansion. All operations (reads, writes, and deselects) are pipelined. ADV/LD should be driven LOW once the device has been deselected in order to load a new address for the next operation. Single Write Accesses Single Read Accesses A read access is initiated when the following conditions are satisfied at clock rise: (1) CEN is asserted LOW, (2) CE1, CE2, and CE3 are all asserted active, (3) the write enable input signal WE is deasserted HIGH, and (4) ADV/LD is asserted LOW. The address presented to the address inputs is latched into the address register and presented to the memory core and control logic. The control logic determines that a read access is in progress and allows the requested data to propagate to the input of the output register. At the rising edge of the next clock the requested data is allowed to propagate through the output register and onto the data bus, provided OE is active LOW. After the first clock of the read access the output buffers are controlled by OE and the internal control logic. OE must be driven LOW in order for the device to drive out the requested data. During the second clock, a subsequent operation (read/write/deselect) can be initiated. Deselecting the device is also pipelined. Therefore, when the SRAM is deselected at clock rise by one of the chip enable signals, its output will tristate following the next clock rise. Burst Read Accesses The CY7C1350G has an on-chip burst counter that allows the user the ability to supply a single address and conduct up to four reads without reasserting the address inputs. ADV/LD must be driven LOW in order to load a new address into the SRAM, as described in the Single Read Accesses section above. The sequence of the burst counter is determined by the MODE input signal. A LOW input on MODE selects a linear burst mode, a HIGH selects an interleaved burst sequence. Both burst counters use A0 and A1 in the burst sequence, and will wrap around when incremented sufficiently. A HIGH input on ADV/LD will increment the internal burst counter regardless of the state of chip enables inputs or WE. WE is latched at the beginning of Document Number: 38-05524 Rev. *L Write accesses are initiated when the following conditions are satisfied at clock rise: (1) CEN is asserted LOW, (2) CE1, CE2, and CE3 are all asserted active, and (3) the write signal WE is asserted LOW. The address presented to the address inputs is loaded into the address register. The write signals are latched into the control logic block. On the subsequent clock rise the data lines are automatically tri-stated regardless of the state of the OE input signal. This allows the external logic to present the data on DQs and DQP[A:D]. In addition, the address for the subsequent access (read/write/deselect) is latched into the address register (provided the appropriate control signals are asserted). On the next clock rise the data presented to DQs and DQP[A:D] (or a subset for byte write operations, see Write Cycle Description table for details) inputs is latched into the device and the write is complete. The data written during the write operation is controlled by BW[A:D] signals. The CY7C1350G provides byte write capability that is described in the Write Cycle Description table. Asserting the write enable input (WE) with the selected byte write select (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. Byte write capability has been included in order to greatly simplify read/modify/write sequences, which can be reduced to simple byte write operations. Because the CY7C1350G is a common I/O device, data should not be driven into the device while the outputs are active. The output enable (OE) can be deasserted HIGH before presenting data to the DQs and DQP[A:D] inputs. Doing so will tristate the output drivers. As a safety precaution, DQs and DQP[A:D] are automatically tri-stated during the data portion of a write cycle, regardless of the state of OE. Burst Write Accesses The CY7C1350G has an on-chip burst counter that allows the user the ability to supply a single address and conduct up to four write operations without reasserting the address inputs. ADV/LD must be driven LOW in order to load the initial address, as described in the Single Write Accesses section above. When ADV/LD is driven HIGH on the subsequent clock rise, the chip enables (CE1, CE2, and CE3) and WE inputs are ignored and the burst counter is incremented. The correct BW[A:D] inputs must be driven in each cycle of the burst write in order to write the correct bytes of data. 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, and CE3, must remain inactive for the duration of tZZREC after the ZZ input returns LOW.

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 tristate prior to low Z under the same system conditions. 19. This parameter is sampled and not 100% tested.
