SST25VF080B-80-4I-QAE-T is a series of 8-pin small and low-power SPI Flash memory ICs. It provides a variety of features such as fast read access time, dual I/O capability, high-speed programming, low power consumption and a small footprint.

SST25VF080B-80-4I-QAE-T has 8 pins (4 IO, 1 CS, 2 VCC, 1VSS). It supports SPI protocol, which inclueds Clock, CS, Data Input, Data Output, and supports dual IO access. The voltage range of VCC is 2.7 to 3.6V DC and the temperature operating range is -40 to +105℃.

SST25VF080B-80-4I-QAE-T is suitable for the majority of small system applications with limited space and operating voltage. It is typically used for code data storage and program distribution, such as communication devices, consumer electronics, automotive and industrial applications.

The features of this part are its 1M-bit memory space, fast random read access performance, dual I/O capability and low-power consumption. It can store up to 8Mbit data, reading rate of up to 55MHz and write rate of up to 25MHz. Its write protect pin can protect whole chip data you write.

The working principle of SSTDVF080B-80-4I-QAE-T is pretty simple. First of all, the CLK signal synchronizes the communication and user data that is read/write to the serial Flash, generated by the CS and DI pin. When CS is low, all the other signals are active. The DO pin will output the bit stream corresponding to the DI pin. Then the memory contents can be read. In write mode, WAIT# pins will be used.

In conclusion, SST25VF080B-80-4I-QAE-T is a low-power, high-speed Serial Flash memory chip, which is the perfect choice for many memory applications such as communication, consumer electronics and automotive systems. It has a small package size, fast read access time and a wide operating temperature range. It’s an ideal way to store and distribute code and data in tight memory limited applications.
