The AT45DB041E-MHN-Y is a new type of memory device developed by Atmel Corporation. It is a 4Mbit serial Flash memory, organized as 32K pages of 128-bytes each. The AT45DB041E-MHN-Y is designed to meet the requirements of a wide range of embedded applications, from secure data storage and secure date transfer to high-speed data acquisition. It features low power consumption, long MTBF, and small package size.

The AT45DB041E-MHN-Y is well suited for applications such as digital image capture, smart cards, automotive electronics, industrial controls, medical instruments, networking equipment, and mobile devices. It combines the traditional serial Flash memory interface (SPI) with the latest industry-standard command set, enabling high speed, low power consumption, and high-density designs. The device is available in 8-pin SOIC, 8-pin DFN, 8-pin PDIP, and 8-pin TSSOP packages.

Application Field

The AT45DB041E-MHN-Y is ideal for a variety of embedded applications that require secure data storage and secure data transfer. It also supports high-speed data acquisition, making it suitable for applications such as digital image capture, smart cards, automotive electronics, industrial controls, medical instruments, networking equipment, mobile devices, and much more.

The device is designed for low power consumption and has a maximum active current of only 30 mA. This makes it a great choice for battery powered applications, as it consumes far less power than traditional memory devices. It is also designed for long term reliability and has an MTBF value of more than 1 million hours.

The device is available in a variety of package sizes, making it easy to integrate into existing designs. It also has an extended temperature range of -40 °C to +85 °C, allowing it to be used in a wide range of environmental conditions.

Working Principle

The AT45DB041E-MHN-Y is a Serial Flash memory device, meaning that it uses a serial data interface to transfer data between the device and the host. The device supports SPI protocol and is compatible with industry-standard command sets. The device features a 4-bit instruction code and an 8-bit address code, allowing for easy integration with existing systems.

The device also features a page read/write algorithm, which reduces the data access time and enables high throughput operations. Data is read and written in units of pages (128 bytes). This makes it easy to access data in memory, as each page can be addressed individually. The device also supports buffered and continuous page read/write operations, allowing for higher throughput data transfer.

The device also features a built-in write-protect feature, which can be used to prevent unintentional and malicious erasure or modification of data stored in the memory. The device also supports an integrated ‘end-of-life’ counter, which can be used to detect when the device has reached its end of life and should be replaced.

The AT45DB041E-MHN-Y provides a high-performance, reliable solution for a wide range of embedded applications, from secure data storage and secure date transfer to high-speed data acquisition. It is ideal for applications that require low power consumption, long MTBF, and small package sizes. The device is also available in a variety of package sizes, making it easy to integrate into existing designs.
