The AT24CS64-XHM-T is a serial 64k bit EEPROM (Electrically Erasable Programmable Read-Only Memory) device, marketed and sold by Atmel Corporation. This memory device components’ primary application field is in the construction of digital devices, systems, protocols, and programs where frugality, low power dissipation, and high data integrity are of high importance. The working principal of the AT24CS64-XHM-T memory device follows the conventional bi-directional two-wire protocol for serial memory ICs, utilizing an I2C protocol.

The I2C protocol is a two way communication protocol with a controller and a slave device that communicate over two wires. The two serial wires exchanged communicate address and data. The two serial wires are called the SDA (Serial Data Line) and SCL (Serial Clock Line). SDA transmits data (address and data) whereas SCL transmits the clock for the timing of data delivery. Both the two bidirectional, serial communication wires get terminated with an open-drain I/O buffer circuit. This allows either the controller, or the connected slave to drive the data line. The devices have pull-up resistors, to the voltage supply, installed on the data and clock lines. To successfully establish a serial clock protocol transmission and allow this device to work, there needs to be an acknowledgement of the device’s address. Each device contains multiple addresses set using the pins A0, A1 and A2. The device can also be written in an address this is done by asserting some of these address pins to 8 or 9th address.

The memory contains an 8-bit control byte and uses 8-bit address pointer. In order to read from the device it is necessary to firstly address it by sending the control byte and then sending a pointer byte setting the designated address either reset to the start or a location stored in memory. After that followed the control byte for proceeding with a read operation which causes the device to output the contents of the designated address. The device includes two unique features, that being a Write Protect pin, and a special Byte Write Instruction. The Write Protect pin is used to physically protect against inadvertent manipulation of the device, whereas the special Byte Write Instruction allows periodic updates of the device’s data without having to rewrite the entire memory. Another of the AT24CS64-XHM-T devices advantageous features is its extremely low power consumption. It requires 6mA when reading and 12mA when writing, using a 3.3V supply voltage. This device operates within the temperature range 0-70C without failure. Additionally, the device also consumes less than 10mW of power in a sleep mode.

In conclusion, the AT24CS64-XHM-T is an efficient and reliable 2-wire serial interface EEPROM device that finds applications in digital devices and protocols where low power consumption, storage capacity and data integrity are highly regarded. It operates with a two-way synchronous data exchange protocol and features various features such as Write Protect, Byte Write Instruction and low power consumption, making it the ideal memory choice for a wide range of applications.
