Overview of the AT25M02-UUM-T

The AT25M02-UUM-T has the capabilities of a standard EEPROM and the advantages of a parallel EEPROM. It is capable of storing up to 2K-bit of memory in a single device. The device is arranged in 16 pages with 64 words and 16 bytes per page. The device also has the capability of unique 128-unit cycle redundancy check for data protection. Additionally, the device also has a built-in 32-bit cyclic redundancy checksum for data integrity.

The AT25M02-UUM-T is also ideal for applications where space is a factor. The device can be used in a small form factor, making it perfect for use in small embedded devices. The device also has a low current consumption and is available in an SOIC-8 package.

Working Principle of the AT25M02-UUM-T

The AT25M02-UUM-T is an electrically erasable programmable read-only memory device. The device works similar to a regular EEPROM. It can read, write, and erase data as long as the device is electronically powered. The data stored in the device remains in its memory until it is powered off.

The device has a 2-wire serial interface. The interface uses either a 4-wire Multi-I/O SPI Protocol or a single I/O SPI Protocol. The device is compatible with several microcontrollers, such as 8-bit, 16-bit and 32-bit microcontrollers, as well as Intel and other microprocessors. The device can also be connected to an external logic circuit.

Data can be read, written and erased from the AT25M02-UUM-T using the serial interface. The device is equipped with a memory write protect pin to protect the data from accidental writes. The device also supports a unique power-off write protection that prevents program and erase operations from being carried out when the power is removed. Additionally, the device has an Extended Device Addressing feature which allows up to 8 AT25M02-UUM-T devices to be connected to the same serial interface.

Application Field of the AT25M02-UUM-T

The AT25M02-UUM-T is ideal for applications that require frequent updates or serial memory operations to save space. It can be used in embedded system applications such as controllerless automation and remote calibration systems, portable devices, and system maintenance in aviation and healthcare. Its low power consumption and small form factor make it an ideal choice for miniaturized solutions.

The device is also suitable for use in applications requiring data protection and long data retention, such as medical and automotive industries. Additionally, the device is ideal for applications requiring secure data storage, such as retail, banking, and identity verification.

The AT25M02-UUM-T is a versatile device that can be used in a wide range of applications requiring reliable and secure data storage.
