Are CY62137FV30LL & CY62137EV30LL Swap in replacement? What is the difference between the two?
Hello,
I am wondering about the max current consumption on this device. On the datasheet it states a max current consumption on a x36 device operating @250MHz with 50% Read cycle and 50% Write cycle at 1080mA for IDD. We are operating VDD at 1.8V and VDDQ at 1.5V. Does this max current rating take into account the current consumed by the VDDQ supply? If it does how can I find the current consumed only by the VDDQ supply?
Thank you!
Show LessCan someone please explain what KA in the PN: CY62167EV30LL-45XIKA stands for. I believe it is the assembly site but can't find which site.
Many thanks in advance,

Show LessWe are considering to use this part in our design and would like to know the weight for our consideration.
I would like to have the attached document if it is a NOR document.
Hi supporters,
Can CY62177EV30LL-55ZXI be replaced by CY62177G30-55ZXI without hardware or software changes?
Please let me know If you have any concerns.
I compared each datasheet, but I could not find critical differences for replacement.
I think the performance of CY62177EV30LL-55ZXI is slightly better than CY62177G30-55ZXI.

For CY62187EV30, data retention should be done in the range of “Ambient Temperature with Power Applied” which is –55C to +125C.
My question is whether the max standby current Isb2 (48uA) is derived by applying the range of “Ambient Temperature with Power Applied”, which is –55C to +125C ?
If not, if it applies “Operating temperature”, which is –40C to +85C, for max Isb2, let me know the “true” max Isb2 by applying the range of “Ambient Temperature with Power Applied”, which is –55C to +125C.
Show LessHello,
I need the land pattern for CY7C2265KV18-450BZC.
Thank you in advance.

Hi, I have a legacy design that uses ISSI IS62WV51216BLL-55TLI . The cross reference tool gives CY62157EV30LL-45ZSXI as a direct alternative. I do not need the low power mode for this SRAM so can I use CY62157DV30L-55ZSI here? We also have tested and used Alliance AS6C8016-55ZIN as an alternative part. The cross-reference tool gives CY62157ELL-45ZSXI as a "similar" part.
I'm having trouble figuring out the part number structure of the above Cypress parts.
