Memory

The SST25VF020B-80-4C-SAE-T is a 2 megabit Serial Flash memory IC, developed and manufactured by Microchip Technology. It is a non-volatile memory, meaning data is not lost during power-down. The memory operates with a single 3V power supply, features a fast data access time of 25ns and a low power consumption of just 30 mW.

Application Field

The SST25VF020B-80-4C-SAE-T is commonly used in applications such as automotive, medical, industrial, aerospace, and consumer electronics. It is particularly used for storing large amounts of data such as system code, program code, configuration data, logos, and graphics. The product is also well suited for mass deployment as it is available in wafer form and provides pin for pin compatibility with industry standard serial Flash memories.

Working Principle

The SST25VF020B-80-4C-SAE-T works by employing a Serial Peripheral Interface (SPI) protocol that allows the device to communicate with other digital devices over a 4-wire bus. It is controlled over the SPI interface and has 4 addresses that can be accessed sequentially based on the command sent from the host. It has an 8-bit data width, which allows it to store a maximum of 16 bytes of data at a time.

The SST25VF020B-80-4C-SAE-T supports various commands such as READ, WRITE, ERASE, and others, enabling users to easily read, write, and erase data as required. The device also provides programmable protection features that prevent unauthorized access to the stored data. In addition, it comes with a built-in sector protection that can be used to lock down specific sectors of the memory, preventing any unauthorized writing or erasing of data.

The device supports multiple speeds, giving users the ability to choose the best speed for their particular application. It can support up to 80MHz SPI bus speed. It also supports 3-byte write addressing and two-byte write/read commands for faster programming/reading. This makes it ideal for storage of large amounts of data.

The SST25VF020B-80-4C-SAE-T is also well suited for applications where data reliability is paramount. It has a high endurance of up to 100,000 program/erase cycles, providing increased data storage lifetime. It also has an ECC (Error Correction Code) feature, ensuring undetectable data corruption. In addition, the device has high temperature and wide voltage operation, allowing it to be used in a wide range of temperatures and supply voltages.

The SST25VF020B-80-4C-SAE-T provides a cost-effective solution for increasing memory capacity and performance, while also providing reliable data storage. The device is also simple to use and can be easily integrated into any system. With its wide range of features and capabilities, the SST25VF020B-80-4C-SAE-T is an excellent choice for any embedded application requiring a reliable and robust non-volatile memory.
