這顆本體右上腳有一個圓形沒有在规格定义里,请帮忙确认 Does anyone here have the .bsdl file for this device? I'm trying to "JTag" this device. Jtag is not working for me. What am I missing here... Hi, I think that the cause of SRAM's data bit inversion is soft error and power supply noise. Are there any other factors that cause bit inversion? If you know other possible factors, please provide us. ... CY14B101LA-BA45XIのIBISが必要です。 CY14B101LA - IBIS https://www.cypress.com/documentation/models/cy14b101la-ibis?source=search&keywords=CY14B101LA&cat=software_tools 上記からダウンロードできるIBISファイルはBGAタイプのSR... Hi, CY62148G30 has an ECC function. Furthermore, This device has not ERR terminal. What happens if multi-bit error occurs? However, the data sheet has the following description. --Data... Hello Cypress Team, We are planning to use your SRAM as alternate to our current SRAM in our board product. But our current part has Address 17 (A17) at pin 30 and Address 18 (A18) at pin 1 from which on your ... We have a question about PIN183401. When we see the DC characterization, power consumption is increasing. Also, junction temperature is changed. Please clarify why these characterization are revised before and after ... Where can I find a data sheet for CY62155 that includes CY62155E-3XWI? If not the full data sheet at a minimum, what does the last "5" denote? The seventh character in the Async SRAM appears to be Bus Width. From t... Hi, we have developed your prototype board using LPC4088 and CY62157EV30LL-45ZSXI. In our project we are using LCD for display process data. LPC4088 having internal LCD controller hence we have mapped frame buffer ... We have a question about CY62147EV30LL-45ZSXI. On datasheet, SRAM 28 pin is NC and it says that we cannot connect to NC pin. 1) To what does NC pin connect inside of the SRAM? 2) If we connect a... Which do you recommend for CY62146GE30-45BVXI & CY62147GE30-45BVXI? I think that CY62146 has better tDBE specs. What is the merit of CY62147? The datasheet references ambient temperatures, both operating range and absolute maximum, but there seems to be no junction temperature information included. Specifically, is there an operating range maximum for junct... I am looking for a direct drop-in replacement for CY62146VLL-70ZI. Seeing that this SRAM chip has gone obsolete, I was looking at the CY62146EV30 MoBL chip. Unfortunately, the EV30 has a different pin-out than the CY6... CY62157EV30LL-45BVXI(VFBGA48)のインターポーザランドの開口径を教えて頂けますか？ Hello, We are using 1Mb ASYNC SRAM CY7C1021DV33-10ZSXI in our new design. The datasheet of this device mentioned 3 modes of write cycle on page - 9 and 10. These modes are - 1) Write Cycle No. 1 (CE Contro... Hello, Customer refer to the SRAM read control by "Figure 15. Read Cycle No. 3" in the datasheet on page 12. In this access, is it possible to read data correctly from SRAM even when "OE goes to Low before CE... We are using four of CY7C1069G30-10ZSXI in parallel to get a 32-bit data bus connected to a FPGA as host. - Is it any need for length matching in the pcb layout when using these SRAM's? - Are there any PCB design gu... Hi, We are using LPC4088 based custom board interfacing external nor-flash(SST39vf3201), SRAM(CY62157EV30LL) & FPGA on static memory CS3, CS1, CS0 respectively. We are using Nor-flash for code storage & execu... Hello, We are using Async SRAM "CY7C1021DV33-10ZSXI" from cypress. As per datasheet and other design guideline document from cypress, there is no length matching requirements listed. but as it is a parallel bus, we... Can I ask whether there are plans to build 5V compliant I2C SOIC8 FRAM devices with a greater capacity than 8k bytes please ?
