Modern electronic devices rely on memory components for data storage and microprocessor operation. AT45DB041A-RC is a 4 megabit (512K x 8) serial dataflash featuring 465K of actual user storage capacity. Comprised of a series of non-volatile memory components, AT45DB041A-RC is a robust and reliable storage solution for microcontroller-based applications requiring high-density storage. This application field examines the physical structure, technology and specifications of the AT45DB041A-RC and its applicable segments in the memory field.

General Construction and Layout

The AT45DB041A-RC is a 4 megabit (512K x 8) serial dataflash that features 465K of actual user storage capacity. It utilizes a serial peripheral interface (SPI) port to communicate with the host processor. The device is divided into 448 sectors. Each sector contains 256 bytes and has an 8-byte unique address. The 8-byte unique address is used to identify each sector within the device. All sectors are organized into sixteen 32K blocks, with each block containing 32 512-byte sectors.

The AT45DB041A-RC is comprised of three main physical segments: a controller, a RAM buffer and the non-volatile memory array. The nonvolatile memory array consists of 16 non-volatile memory bits or cells. Each bit is divided into two halves and is programmed and erased independently. This allows the controller to perform a read, write and erase operation on a single bit simultaneously.

Technology and Principle of Operation

AT45DB041A-RC utilizes a Serial Peripheral Interface (SPI) protocol to communicate with the host processor. It is based on nonvolatile Flash EEPROM technology which enables high-speed memory access. The data stored in AT45DB041A-RC can be retained for up to 10 years, making this an ideal solid-state storage solution for many applications.

AT45DB041A-RC utilizes an on-chip internal voltage regulator to generate a supply voltage for the memory array and allow for a single supply operation. The device also features advanced Error Correction Code (ECC) technology which improves the bit error rate, thus increasing overall reliability and data integrity.

To read the data stored in the AT45DB041A-RC, it first sends the read command and address to the SPI bus. This bus then sends the requested data to the host processor. The write process is executed in a similar manner, but instead of receiving data, the device sends the data to be written to the memory array. Once the device receives the write command, it writes the received data to the corresponding locations in the memory array. The erase process is similar to the write process. The device sends the erase command to the memory array and erases the data stored in the specified locations.

Application Field

AT45DB041A-RC is suitable for use in a variety of microcontroller-based applications that require high-density storage, such as automotive applications, consumer electronics, medical equipment, industrial control, and telecommunications. Furthermore, due to its fast access time, it is also suitable for applications with high performance requirements. Additionally, it is suitable for applications where data integrity and reliability are critical, as the device features advanced Error Correction Code (ECC) technology which improves the bit error rate, thus increasing overall reliability and data integrity.

In conclusion, AT45DB041A-RC is a 4 megabit (512K x 8) serial dataflash featuring 465K of actual user storage capacity. It utilizes a serial peripheral interface (SPI) port to communicate with the host processor, and is based on nonvolatile Flash EEPROM technology which enables high-speed memory access. It is suitable for use in a variety of microcontroller-based applications and applications with high performance requirements. Additionally, it features advanced Error Correction Code (ECC) technology which improves the bit error rate and increases overall reliability and data integrity.
