The device here lists 1.65 V-2.2 V and 4.5 V-5.5 V, but not 2.2 V-3.6 V. If I want to run the device at 3 V, should I use the 5 V value as a reference?

Comparison between the two as seen from the Logic Block Diagrams & Pin configurations as shared here in  gives one to understand , there is No difference between CY7C1041GN & CY7C1041G .

NC Pins in both CY7C1041G & CY7C1041GN are Not Connected Internally to the Die.

CY7C1041G is supposed to be a part with ECC, while CY7C1041GN is identified as No ECC  as for the PCN . Confusing indeed!!!!

CY7C2663KV18 NC Pins some of the NC Pins can I connect to GND and VDDQ
In my design Iam using CY7C2663KV18 QDR-II part.
For NC Pins connection, in datasheet It is mentioned that "NC/288M and NC is not connected to the die and can be tied to any voltage level".
Can I connect some of the NC pins to GND and some of the NC Pins to VDDQ or VDD for PCB feasibility? Is it recommeded?

(1) In the RAM ARRAY section, 1M x 16/2M x 8 is shown, and depending on the input status of the control signal, either of these configurations can be changed (contents of the Truth Table).
This is the same for CY62167EV30LL-45ZXIT under the same conditions, is this correct?
Is it correct that CY62167EV30LL-45ZXIT will have the same configuration under the same conditions?
(2) CY62167G30-45ZXIT has newly added ECC ENCODE and ECC DECODE on the block diagram, how much response delay does this cause?
Or is it correct to assume that the block DATAin DRAIVERS, RAM ARRAY, and SENSE ARMS, which are also in CY62167EV30LL-45ZXIT, have a different configuration than before, and the delay is offset by the faster response speed in these areas?
(3) Just to be sure, please let us know if there are any important access timing points when using CY62167G30-45ZXIT.
(5) Just to be sure, if there are any important points in access timing when using this RAM, please let us know. If you say that it is sufficient to satisfy the AC characteristics described, that is OK.
I heard that CE must be asserted after the address is determined due to operation restrictions by other manufacturers,
I had to put in an extra WAIT to compensate for the response delay of the ECC circuit, and so on.
This is a confirmation of the problem.
(4) The recommended operating voltage of the CY62167G30-45ZXIT is 4.5 to 5.5V, whereas the CY62167EV30LL-45ZXIT
Is it correct to assume that the specifications are the same as when the product is used at 4.5 to 5.5V?
Is it correct to assume that it is the same as when using 4.5 to 5.5V?

Are there any time restrictions, etc. for BHE/BLE with respect to address signals?

For example, Liontech's SRAM　LY62L409716A(https://protect2.fireeye.com/v1/url?k=31323334-501d0a38-31314cae-454441504e31-b458843b1000309f&q=1&e=e607cbae-0409-4a20-a0c6-d6eae17bbeb4&u=http%3A%2F%2Fwww.lyontek.com.tw%2Fpdf%2Flp%2FLY62L409716A-1.2.pdf%29%25E3%2581%25A7%25E3%2581%25AF%25E3%2580%2581

Need a clarification for CY62157EV30LL-45ZSXI (Supposed to be 90nm Process Product ) received with Mark Die Revision AB33 which is from UMC Fab site 12A, could be of 65nm Process Product ?  

If it is a 65nm Process, how come the Device Top Marking is CY62157EV30LL-45ZSXI?

Hello,

The customer is considering reducing the power consumption of equipment that is in standby mode for a long period of time.
The power supply to Sync SRAM cannot be stopped because it is shared with other devices.
Therefore, I'm thinking of stopping the clock signal from FPGA to SRAM to reduce power consumption.

1) What is the current consumption of SRAM in Standby: Clock stopped?
2) This SRAM has DOFF# (PLL turn off).
Is it possible to reduce power consumption by setting this pin to High as well?
What is the current consumption with Clock stopped and PLL turned off?

MPN: CY7C2265KV18-550BZXI
