The 25AA080D-I/SN is a Memory device. It is a serial 8-pin 512Kb EEPROM that offers a flexible architecture to address a range of user requirements. The EEPROM provides an effective storage solution for applications that require data protection and reliable mind store. This device is available in a variety of packages, including both standard and extended temperature variants.

The 25AA080D-I/SN is programmed and erased while packaged in the end system, eliminating the need for handling, testing, secure storage and packaging of individual devices.

The 25AA080D-I/SN offers an array organization of 32K words in 256 pages of 128 x 8 bits. It supports memory write operations up to 512 bytes, support for partial-page write, and up to 10 bytes addressing to control the location in the memory array. For memory protection, the 25AA080D-I/SN features an endurance of 1,000,000 write cycles per byte and more than 10 years data retention. The device provides a secure code/dataprotection with a lockable page capability. By locking a page, the user is assured that the program code or data stored in the specified area will not be altered.

The 25AA080D-I/SN is a three-wire serial EEPROM. This device uses a protocol based on the Serial Peripheral Interface (SPI) protocol. The data path consists of shift/no-shift, read/write, serial data input and serial data output pins, and allows data to flow synchronously between the 25AA080D-I/SN and the microcontroller or other external components.

The 25AA080D-I/SN device supports eight write cycles, with each cycle representing a single byte. When the write cycles for a single byte are completed, the data is verified and stored in the EEPROM. The 25AA080D-I/SN supports a page write cycle that minimizes the number of transistor accesses to a full page. This feature reduces power consumption, since the additional write cycles are not necessary when a page is loaded with data.

The 25AA080D-I/SN provides protection against accidental write attempts by using a write protect signal. This signal will effectively prohibit any write access to the data stored in the EEPROM. Additionally, the 25AA080D-I/SN can be put into an idle mode or deep power-down state to reduce power consumption.

The 25AA080D-I/SN is an ideal choice for a range of applications that requires robust data storage, such as consumer electronics, industrial automation, medical equipment and automotive applications. It is characterized for industrial temperature up to 125°C, with a read speed of up to 25MHz and a write speed of up to 10MHz. The 25AA080D-I/SN is ideal for applications that require a high-performance, highly reliable, and minimal amount of power.
