AT25DF041A-SHF-B is a 4-Mbit Serial Flash Memory device produced by Adesto Technologies, belonging to the Memory category. It is a non-volatile memory device which supports a variety of serial protocols, including SPI, QSPI, and Dual SPI. This device features a density of 4Mbits, with a single-cycle erase and a variety of programmed programming times. The AT25DF041A-SHF-B has a 20MHz maximum clock frequency and is available in SOIC, SSOP, TSSOP, and BGA packages.

AT25DF041A-SHF-B is an ideal choice for a wide range of applications including industrial systems, automotive, communications and consumer electronics. The device has an operating temperature range of -40°C to +85°C, making it suitable for a variety of operating environments. The device also provides an extended operating voltage range of 1.8V to 2.85V.

The working principle of AT25DF041A-SHF-B is based on the common Flash (volatile) technology. It is a single power supply device which allows serial interfacing from 1.8V to 2.85V and transfers data at a maximum rate of 20MHz. When the device is power-on, CE#, the clear enable is high, the device is reset and all internal registers are cleared. WE#, write enable, is selected to enable write operations. The device has a page write mode, which can write up to 256 bytes of memory at one time. The device also has an auto address increment feature which automatically increases the address after each write operation.

For read operations, the CE# is low, the user can select the desired address and then initiate a read command. The data is then clocked out with the rising edge of the clock. The device supports multiple read memory array protocols, such as Standard SPI, Dual I/O SPI and Quad I/O SPI. The device also supports sector protection, software unlock and an array read access command.

AT25DF041A-SHF-B has an endurance rating of 10,000 cycles and a data retention of 20 years. The device features an 8 bit Manufacturer ID, 8 bit CKS status and a unified status register. The device also features a unique 1-byte JEDEC ID, another 8-bit identifier, that is not shared between different manufacturers and is used to identify the manufacturer’s devices.

AT25DF041A-SHF-B is an excellent choice for a variety of applications and has proven to be a reliable and cost effective solution for non-volatile memory needs. It is capable of natively supporting the latest generation of serial interface controllers, providing a fast and efficient solution for data storage and retrieval. With the wide operating temperature range and low power consumption, the AT25DF041A-SHF-B makes an ideal solution for any application that requires secure non-volatile storage.
