ZB25VQ40B is a high-performance,high-stability nonvolatile flash memory chip,which is specially designed for embedded storage scenes with miniaturization,low power consumption and high-speed transmission.Flash memory chip is equipped with universal standard serial peripheral interface(SPI),which is compatible with various transmission protocols.With excellent transmission rate,reliable storage performance and flexible adaptability,it has become the preferred storage chip for firmware storage,code running and data caching of various intelligent devices.
 

In terms of interface and transmission performance,this flash chip supports conventional single I/O SPI transmission mode,and is compatible with dual I/O and four I/O multiplex transmission protocols,which is the common SPI multi-I/O(MIO)technology in the industry.The standard working clock frequency of flash memory chip can reach 133MHz,the equivalent clock rate of dual-channel I/O can reach 266MHz,and the maximum equivalent rate of four-channel I/O transmission mode can reach 532MHz.The transmission performance far exceeds the traditional 8-bit and 16-bit parallel flash memory,which greatly improves the data reading and writing efficiency of equipment.The chip is equipped with exclusive clock,chip selection,data input and output,write protection and holding pins,and with top and bottom array control functions,which can flexibly adapt to various hardware circuit designs.
 

In terms of functional configuration,ZB25VQ40B flash memory chip adapts to the mainstream specifications in the industry,supports JEDEC standard registers,128-bit unique serial numbers and three sets of 512-byte security registers,and ensures equipment traceability and data security.At the same time,the flash chip is equipped with programmable write protection,software reset,automatic incremental reading,8/16/32/64 byte continuous reading and other practical functions,which can directly support code execution in place(XIP)and code shadow memory operation,and adapt to the operation requirements of most embedded devices.
 

In terms of hardware parameters,the flash memory chip is powered by a single power supply of 2.3V-3.6V,and is equipped with a storage capacity of 4M bits.The storage structure contains 2048 pages of storage cells,and the programmable capacity of a single page is 256 bytes,which supports reading and writing in 4K unified sectors and 32K/64K blocks.Flash flash chip products support dual industrial-grade temperature zones of-40℃to 85℃and-40℃to 105℃,and are suitable for harsh industrial scenes.Excellent power consumption performance,typical standby current is only 10μA,turn-off current is as low as 1μA,and it has over 100,000 erasing life,stable data retention ability for more than 20 years,low power consumption and high durability,which effectively reduces equipment operation and maintenance costs and adapts to various intelligent hardware storage scenarios with compact space and limited power consumption.
