AT45DB161D-TU-2.5 Memory

The AT45DB161D-TU-2.5 serial data flash memory is a high-performance, non-volatile memory designed to address the needs of low-power embedded applications where data integrity, reliability and write endurance are critical. It is capable of storing up to 2Gb of data in its lifetime (2,048K x 8 bits). The devices come in an industry-standard, 8-lead SSD and can be used as a standalone memory, or combined with a larger number of memories for additional storage capacity.

Application fields and working principle

The AT45DB161D-TU-2.5 memory device is suitable for an array of applications, including but not limited to: mass storage, embedded microcontrollers and Internet-of-Things (IoT) devices. The device is capable of data retention up to 10 years and features a continuous read/write cycle endurance of up to 100,000 operations/second.

The AT45DB161D-TU-2.5 device consists of an array of memories and controllers, which enable it to perform various instructions. The device incorporates a Page Write (PW) function, which allows the device to write up to 8K byte of data in a single instruction. Additionally, the device also provides error checking and command status functions.

In order to read data from the device, the remote interface is used. This can be done through the use of a bus protocol, such as I²C, SPI or UART. The data stored in the device is organized in 8K bytes pages per device, which enables the device to store large amounts of data and also allows for quick access to the stored data.

The AT45DB161D-TU-2.5 device also features a unique Page-to-Buffer program function. With this function, the user can copy a page of data for temporary storage in the device’s onboard buffer. This allows for faster writing or data integrity checks on the page, as the data can be quickly retrieved from the buffer.

The device also features a Built-in Power-on Reset (POR) circuit that resets the device once power is applied. This feature helps in ensuring reliable operation of the device in case of power loss.

In order to ensure reliable data storage and retrieval, the AT45DB161D-TU-2.5 device also incorporates an on-chip power-on-self-test (POST) circuit. This circuit checks and verifies the integrity of the device’s internal circuitry and memory array.

The device also provides a variety of security features that can be used to protect stored data from unauthorized access. These features include password lock, write counter limit and Erase/Program Suspend/Resume functions.

The AT45DB161D-TU-2.5 device is an excellent choice for applications that require data integrity, reliability and write endurance. With its easy to use features, reliable operation and simple interface, the device is well-suited for low-power embedded applications.
