AT45DB021-TI is a high-density Flash memory chip, which is mostly used in embedded systems for data storage. It is a type of memory that is non-volatile and can store data without power. It has a small form factor and low power consumption, making it suitable for a wide range of applications. This article will discuss the AT45DB021-TI application field and working principle.

As an embedded memory solution, the AT45DB021-TI offers extensive advantages. It is a non-volatile memory that can store data without power and has a fast data access rate. It also has low power consumption and a low form factor, making it ideal for a variety of applications. It is also highly reliable, offering high data retention and endurance.

The AT45DB021-TI is a synchronous memory device, meaning that it can be clocked to read and write data. It has page size of 256 bytes and uses a double-byte address for data addressing. It can also be accessed in multiple read/write modes, such as sequential, page read, page write, and buffer read. The data access rate for the device is up to 20 Mhz.

In addition to its fast data access rate, the AT45DB021-TI has built-in error correction and data security features. It supports hardware-based error correction with a 16-bit syndrome code and hardware-based data protection using a hardware lock. The hardware-based security prevents unauthorized access to the memory contents and prevents data loss in case of a power failure.

The AT45DB021-TI is also designed for low-power operation. It utilizes a standby mode that reduces power consumption by more than 90%. The device also has an ultra-low-power read mode, which reduces the operating power by 20%. These features make the AT45DB021-TI ideal for low-power applications such as embedded, battery-operated, and mobile devices.

The AT45DB021-TI is also available in a variety of configurations. It is available with 1Mb, 2Mb, 4Mb, and 8Mb capacities. The device can also be configured for single-voltage operation and can operate from a voltage range of 1.8V to 3.6V. There are also several packages available for the AT45DB021-TI, including TSSOP, SOIC, DFN, and LFBGA.

Overall, the AT45DB021-TI is an ideal memory solution for embedded systems. It offers fast data access and low power consumption, as well as reliable data protection and error correction. It is available in a variety of configurations, making it suitable for a wide range of applications. For these reasons, the AT45DB021-TI is an excellent choice for embedded systems requiring a low-power, high-performance memory solution.
