AT25128B-SSHL-T is a low-voltage serial EEPROM that belongs to the SPI Bus Family of EconoRAMTM. It is a 128Kbit self-contained, low-power serial CMOS EEPROM that operates from 1.8 to 5.5V supply voltages and supports the industry standard Serial Peripheral Interface (SPI) protocol. The two interface protocol instruction set includes inter-processor communications, addressable read and write operations, sequential read and write functions and SDA detection for communications capability. It is suitable for use in space-limited applications.

The AT25128B-SSHL-T is available in 8-pin SOIC, 8-pin TSSOP (width) package, as well as in 8-pad UDFN (height) package. It has several identification modes, each with a different byte size, these allowing the device to be selected from a wide range depending on the application. The device can also be identified for programming by the use of a special programming sequence and the output of a special read-write data bit.

At present, AT25128B-SSHL-T is widely used in important industrial fields such as computers, networks, factory automation, automotive electronics, aerospace, personal electronics, and military applications. The AT25128B-SSHL-T is also widely used as a programmable memory which can store data, programs, or other information which is kept permanently accessible even when power is turned off.

The working principle of the AT25128B-SSHL-T is very simple. First, the user sends the instruction and address commands over the serial data lines to the device, then the device responds to the instruction for selecting a specific mode of operation. After the device receives an instruction, the instruction is decoded and processed. Depending on the instruction, data can be written, read or erased. The device then sends an acknowledgement to the user illustrating that the instruction has been successfully executed. A detailed instruction set is provided for use in the respective applications.

The AT25128B-SSHL-T is designed with a variety of advanced features to ensure its stability and reliability, such as high speed communication, low power consumption, fast write/erase time and an extended operating temperature range. The device is also compliant to the SPI protocol and is suitable for use with 8, 16, and 32-bit microcontrollers. It is an ideal choice for industrial applications where a secure, reliable and fast data storage device is required.

Overall, the AT25128B-SSHL-T is a perfect choice for integrated and industrial applications requiring robust performance and data integrity. It is an ideal choice that offers reliability, high speed, low power consumption and extended operating temperature range.
