AT28BV256-20SU-T Application Field and Working Principle

AT28BV256-20SU-T is basically designed to store nonvolatile memory in a microcontroller system. It combines the capability of a nonvolatile SRAM with the power benefits of a nvSRAM. The chip enables high speed serial operation and requires no external component for interfacing and programming. The device requires both an active low CS and an active low OE to enter the write mode so data can be programmed into individual SRAM registers.When an active low CS and an active low OE is provided, the CE pin can be used to define the write address.Additionally, the AT28BV256-20SU-T provides two other pins.The WAN pin is used as a write enable control, while the READ pin is used as a read control.

The nonvolatile SRAMs are used in a wide range of applications such as automotive, industrial, medical, and data storage. AT28BV256-20SU-T is the best choice for applications that need low power consumption while still require data retention after power outages.Applications like settings management, calibration memory, and real-time clock can all benefit from this device.

The AT28BV256-20SU-T can be operated in a ready/sleep mode for extremely low power consumption.In the ready/sleep mode, the device can save the contents of the memory,including any write cycles that have been performed, when power is removed. The chip particularly features a low standby current of 10 uA and minimizes power consumption when not in use. This helps extend battery life for applications running on battery power.

The AT28BV256-20SU-T is designed in a very reliable way that allows the device to be used in a variety of conditions with no external support required. It is optimized to support a wide range of operating temperatures between -40°C and +85°C. This is an important feature in critical applications, such as those used in the medical industry and automotive. Additionally, the device can withstand against various shock and vibration conditions without loss of the data.

In summary, AT28BV256-20SU-T is the ideal device for storing parameter and calibration values for microprocessor systems, as it combines the advantages of low power consumption and the self-contained interruptible write cycle of an EEPROM. It enables high speed serial operation and requires no external component for interfacing and programming. Moreover, it is able to withstand a wide range of operating temperatures and shock and vibration conditions.
