In all kinds of embedded systems,industrial control and consumer electronic devices,high-speed and reliable external storage solutions are very important.External sram has become a key part of many designs because of its high-speed access,simple interface and stable data.
This EMI 4Mbit external sram is made by advanced all-CMOS technology,and its organizational structure is 512K x 8 bits,which provides a balanced storage capacity and data bit width.Its working voltage range is 2.7V to 3.6V,and it is well compatible with common 3.3V systems.It also has TTL-compatible interface and tri-state output function,which ensures convenient connection with many mainstream controllers(such as MCU and DSP).The externally expanded sram chip provides a variety of package options such as 32SOP,32sTSOP1,44TSOP2 and 48FBGA,which provides a high degree of design flexibility for PCB layout and space-limited applications.
The core design concept of extended sram products focuses on ultra-low power consumption and high reliability.In standby mode,its typical current can be as low as 1μA,which significantly prolongs the battery-powered equipment(such as portable medical instruments and handheld terminals).At the same time,the external sram supports the data holding voltage as low as 1.5V(the minimum value),which greatly facilitates the design of battery backup scheme and ensures that key data is not lost when the main power supply of the system is turned off.Its access time is 55ns,which meets the needs of most medium and high-speed applications while maintaining excellent power consumption performance.
In order to cope with the complex application environment,this externally expanded sram chip has industrial robustness.Its working temperature range covers-40 C to 85°C,and it can stably run in harsh conditions such as high-temperature industrial sites,outdoor equipment or automobile electronic cabins.This wide temperature characteristic,combined with its low power consumption design,makes it an ideal choice for automotive electronics,industrial automation,communication base stations and other fields with high reliability requirements.
