ISSI IS61WV5128EDBLL domestic alternative scheme

As a classic 4Mbit high-speed asynchronous SRAM,IS61WV5128EDBLL adopts 512K×8bit architecture,and has its own ECC error correction capability.The access speed covers 8ns and 10ns,and the industrial temperature range is-40℃~+85℃.It is widely used in FPGA external cache,data acquisition unit and other scenarios.However,due to the influence of the supply chain cycle,the delivery date of this material is prolonged.Therefore,Yingshangwei has introduced a domestic SRAM alternative with low board modification cost-Weiling Chuangxin EMI504HF08VA.
 

EMI EMI504HF08VA is a domestic pin-to-pin replacement model adapted to this ISSI SRAM IS61WV5128EDBLL,and it is also a relatively safe alternative in the current supply chain.The chips are both 4Mbit and 512K×8bit storage organizations,packaged in 44 TSOP2 standard,and the pin definitions are aligned.The original PCB layout does not need to be revised again,which greatly shortens the project switching cycle and is suitable for Shuang Yuan BOM backup of production projects.
 

EMI504HF08VA is a completely static asynchronous SRAM,which needs no clock and refresh operation,and the control logic is simple,which reduces the workload of driving and debugging on the main control side.The speed gear is available in 8ns/10ns/12ns,with sufficient timing margin.It also supports the industrial working environment of-40℃~+85℃and adapts to the temperature and performance requirements of most original projects.
 

As an EMI agent,RAMSUN can provide stable spot support and alleviate the risk of project stoppage caused by the fluctuation of overseas storage chip supply.It is suggested that the board-level time sequence and high and low temperature stability verification be completed before the project falls to the ground to ensure the long-term and reliable operation of the system.If your project is evaluating the replacement of domestic SRAM of ISSI IS61WV5128EDBLL,please contact us to carry out scheme evaluation,apply for sample measurement,and simultaneously obtain the selection data of other ISSI compatible models of EMI SRAM series.
