The 25AA1024T-I/SM memory is an advanced serial communication device widely used in many fields, including industrial/commercial/military. It provides non-volatile electric read/write capability and wide voltage operation range. The device incorporates a 1024Kbit EEPROM memory array, organized as 256K x 8 bits. The memory can store up to 256K bytes of data, and its wide supply voltage range of 2.7 - 5.5V makes it suitable for a variety of applications.

The transceiver pins of the 25AA1024T-I/SM provide two-way communication between the device and the host microcontroller/computer. The host initiates a communication through the device by sending a start condition followed by the appropriate data bytes. The device responds with the appropriate data bytes or informs the host if an error occurs. The execution time for any command is very short, typically a few microseconds.

The 25AA1024T-I/SM memory has the following features:

• 256 Kbit EEPROM memory array organized as 256K x 8 bits
• Operates from a single +2.7V to +5.5V supply
• Serial communications interface (I2C) with data rate up to 1 Mbps
• Serial communications interface (SPI) with data rate up to 10 Mbps
• Accepts both 7 and 8 bit device address formats
• Integrated 4-wire serial communications protocol
• Simple byte-level operations on any page
• High speed write/read/erase
• Small 8-pin (6mm x 8mm) package

The 25AA1024T-I/SM\'s working principle is typically one in which commands are written to the device through its I2C or SPI interface. Depending on the type of command, data or addresses are then transferred to the memory array. During the write command, the storage location is determined by the address on the I2C or SPI bus and the data is loaded into the memory array. During the read command, the data is transferred from the memory array to the corresponding locations in the I2C or SPI bus. Erase commands are also supported, which erase the whole memory array as well as selectable pages or bytes.

The 25AA1024T-I/SM memory device is ideal for a variety of applications including, data logging, embedded systems, medical instrumentation, consumer electronics, industrial process control, and military applications. With its wide supply voltage range and its integral serial communication features, it is well suited for embedded systems and portable, battery powered devices.
