PSRAM(pseudo-static random access memory)combines the advantages of SRAM interface convenience and DRAM storage density.Compared with the traditional DDR running memory,PSRAM does not need a complex external refresh controller,and its internal structure integrates a self-refresh logic circuit,presenting a simple interface compatible with SRAM.This design not only retains the advantages of easy control of SRAM,but also realizes the storage density close to DRAM,which can effectively simplify the development process of hardware products,reduce the cost of bill of materials,and help enterprises control the overall budget while ensuring product performance.
The EMI164LA16LM-70I series PSRAM chip introduced by Weiling Chuangxin provides 64Mb capacity,adopts the organization form of 4M x 16bit,has the working voltage range of 1.7 to 1.95V,the access speed reaches 60 to 70ns,and is packaged in 48BGA.The memory array and control logic are integrated in the chip,and there is no need to match external memory chips,which not only saves PCB wiring space,but also reduces the complexity of the overall scheme.It is suitable for space-limited and cost-sensitive use scenarios such as smart home appliance control panels,basic human-computer interaction devices and simple desktop display modules.
The low power consumption performance of Weiling Chuangxin PSRAM brings a longer standby capacity for smart products,which is especially suitable for consumer electronic products that need to run for a long time.At the same time,because PSRAM itself has the ability of data cache and instruction storage,developers do not need to add a separate power management unit or DDR running memory,which not only optimizes the power design,but also reduces potential failure points.For typical tasks such as interface rendering,control instruction caching,and lightweight information processing,PSRAM can provide sufficient bandwidth and stability,which helps the product to achieve a balance between low cost and high reliability.
As the first-class agent of Weiling Chuangxin,Yingshang Microelectronics provides a complete range of psram products and has a professional technical support team,which can provide customers with services from selection to customization.If you have any product requirements related to psram,please feel free to call.
