With the rapid iteration of the Internet of Things and wearable devices,a memory chip with low power consumption,small size and high adaptability has become the core requirement of embedded devices.Cascadeteq's domestic CSS3204LU PSRAM chip,represented by
RAMSUN,has become the preferred storage solution for lightweight smart devices with excellent transmission performance,minimalist interface design and stable industrial-grade working ability,and is widely suitable for various low-power portable terminal scenarios.
First,the core advantages of CSS3204LU PSRAM chip
This 32Mb PSRAM chip adopts an innovative low-pin-count interface architecture,is equipped with four SDR I/O pins,supports SPI serial peripheral interface and QPI four peripheral interface dual working modes,and flexibly adapts to the docking requirements of different devices.The highest working frequency of PSRAM can reach 133MHz,and the accurate latching of instructions,addresses and data is completed by relying on the clock(CLK),thus ensuring the stability of high-speed data transmission.
Second,the power consumption and temperature characteristics of PSRAM
CSS3204LU PSRAM adopts single power supply mode,and its working voltage range is 2.7V-3.6V.When the voltage is stable at 3.0 V 10%,the main frequency of PSRAM chip can reach 133MHz；.Under the 3.3v 10%working condition,the main frequency can reach 109MHz,and the multi-working condition is suitable for different equipment power supply environments.The storage architecture of the product is 4M×8 bits,with a comprehensive addressing range.It supports two packaging burst modes of 1kbyte and 32byte,and can adapt to different data transmission scenarios as required.At the same time,it is equipped with software reset function,which makes equipment debugging and operation and maintenance more convenient.
Third,PSRAM core application scenarios
Relying on the comprehensive advantages of high speed,low power consumption,small size and high stability,CSS3204LU PSRAM chip perfectly adapts to industrial-grade temperature conditions(-40℃to+105℃),and is mainly used in low-power embedded scenes such as smart wearable devices,portable electronic terminals,Internet of Things sensor devices,etc.It is a cost-effective alternative to domestic PSRAM.
