It is an advanced non-volatile memory device, offering data retention of more than 100 years and random write/erase performance of greater than 25,000 cycles. The AT21CS11-UU0B-T has 32Kbits of memory. It is a low-cost, low-power solution for applications that require reliable non-volatile storage.

Application Field

The AT21CS11-UU0B-T is widely used in consumer, commercial and industrial products, including computer systems, medical devices, handheld digital electronic devices, automotive devices, security systems, etc. It offers non-volatile storage for system configurations, device settings, etc. The AT21CS11-UU0B-T is capable of operating in a wide range of temperatures, which makes it suitable for use in harsh environments, such as automotive applications.

Working Principle

The AT21CS11-UU0B-T is a serial communication interface (SCI) chip based on SPI bus protocol. It uses its 32Kbits of memory to store data. The data is stored in a 16-bit EEPROM, and is organized in blocks of 16 bytes. Data is written or erased at specific address locations.The chip supports the following commands: Write-Data, Read-Data, Read-Status, and Erase. The Write-Data command can be used to write up to 16 bytes of data in a single operation, while the Read-Data command can be used to read up to 16 bytes of data from the memory. The Read-Status command can be used to check the status of the chip, to ensure that data written to the memory has been properly stored. The Erase command can be used to erase a single block of 16 bytes, which is the equivalent of a page of memory.The AT21CS11-UU0B-T also features error-detection and correction methods, to ensure that data written to the memory is valid and protected from corruption. The chip can also support write-protection, allowing portions of the memory to be kept as read-only.

Conclusion

The AT21CS11-UU0B-T is a versatile and reliable non-volatile memory device that can be used for a wide range of applications. It is ideal for applications that require reliable long-term data storage, and the chip supports a variety of commands that facilitate the writing and erasing of data. The chip also features error-detection and correction methods, and write-protection, to ensure that data written to the memory is valid and secure. With its wide range of features and its superior performance, the AT21CS11-UU0B-T is an excellent choice for applications that require reliable non-volatile storage.
