Working Principle

25LC080AT-E/SN is an 8-pin ROM memory which uses the SPI protocol to transfer 8-bit data bytes to and from a microcontroller or other devices. It allows the user to read and write data to the registered device via an 8-bit data bus. The 25LC080AT-E/SN has a high speed interface with data rates up to 10MHZ in 400KHz address-word mode.

The 25LC080AT-E/SN has a page write sequence with the first byte being the most significant byte in the page, with succeeding bytes being written from the least significant byte forward. It also has a write-protect feature which is used to enable or disable write protection. The device has a Power-on Reset (POR) feature which resets the device front-end logic and restores the status of the device’s internal registers and memory array.

It also has a Power-Down function which reduces the power consumption of the device by putting it into a low power sleep state. The device may be woken up using an external interrupt or by the microcontroller. The 25LC080AT-E/SN has an optional Hardware Write-Protect (HWP) pin which is used to enable or disable writes to the device. The device also has an internal 7-bit address counter, which can be programmed to store the starting address from which memory access occurs.

The 25LC080AT-E/SN supports two programming commands: Erase-all and Program. The Erase-All command is used to erase the entire memory array and the Program command is used to write data to the memory array.

In summary, the 25LC080AT-E/SN is an 8-pin serial EEPROM which is intended for use in automotive, industrial, and consumer applications. The 25LC080AT-E/SN is designed to provide non-volatile serial communications, allowing easy integration into new applications or existing designs.
