Any data/Test results to show that STK11C88-SF45TR can be used beyond its defined temperature range of 0 to 70 Degrees C?
I am looking for a drop in replacement for the STK11C88-SF45I part, I was not able to find any part except STK11C88-SF45TR. But the STK11C88-SF45TR has a operating temperature range of 0 to 70, I am looking for a 

Hi Team,

We are going to propose "CY62148EV30LL-45ZSXIT" as a replacement for our current production renesas SRAM "RMLV0408EGSB-4S2#HA1". We need some parameter clarification

1. t_OW - Output enable from write end (nS) , this timing parameter is not  present in the cypress datasheet, in renesas datasheet its 5ns, Below is the image snipped from renesas datasheet where t_{OW is highlighted.}

_{Could you please provide the timing of that parameter.}

2. In capacitance, cypress datasheet  provide as input and output capacitance as separate but in our current renesas part input and input/output capacitance is mentioned.

I want to know the input/output capacitance value, so that I can compare both the parts.

The CY7C2663KV18/CY7C2665KV18 datasheet only provides the max value for the IDD (VDD supply current). What is the typical value for this supply current? Also, is read current and write current the same value? The operation current is calculated with 50% read cycle and 50% write cycle per note 29., but that's all the information we are given.

Hello

The attached document obtained from the official website states that BGA has two types of internal structures.

(Stack product or regular product)

●How can I tell these apart?
●Which is the internal structure of CY7C1041GN30-10BVXI?

以下PCNの内容について確認させて下さい。

１．案内文面に完全に互換性有とあります。

　Greatek Electronicsで製造された製品は、既存製品と形状、機能、パラメータ、および品質性能において、

　部品性能に関する情報のみ互換、と言う理解でよろしいでしょうか？

２．Mold材、Lead Frame、Lead Finish、内部配線材等々異なっていることが明白な中

　部品管理上・部品実装上で注意する点・異なる点は本当に無いのでしょうか？

３．RoHS,Reach,CMRT等環境上の問題や使用量に対する問題は無いのでしょうか？

４．互換性がありとは、電気的差分は0,ほぼない,少しはある

　　の何れを認識していればよろしいでしょうか？

以上、宜しくお願い致します。

We are going to propose "CY62148EV30LL-45ZSXIT" as a replacement for our current production renesas SRAM "RMLV0408EGSB-4S2#HA1". while analyzing we found address line pinout A17 and A18 of the cypress part is interchanged when compare to the renesas part.

We have to clarify, is there any impact in our existing design because of this pinout change?

Please explain this.

ソフトエラー率を教えて下さい。

また、ECC付きの場合、ECCによってソフトエラー率がどの程度低減されるかについても、

ご教示お願い致します。
