AT24C64

The AT24C64 is a type of EEPROM (Electrically Erasable Programmable Read-Only Memory) chip produced by Microchip Technology. It offers a storage capacity of 64 kilobits, or 8 kilobytes, making it suitable for storing small amounts of non-volatile data in various electronic applications. The chip communicates using the I2C (Inter-Integrated Circuit) protocol, a two-wire serial interface that facilitates easy communication with microcontrollers and other devices.
Key features of the AT24C64 include low power consumption, a wide operating voltage range (typically 1.7V to 5.5V), and a high endurance rating of typically 1 million write/erase cycles. It also provides data retention for up to 100 years. The chip is used in applications such as consumer electronics, automotive systems, and industrial devices where reliable data storage is needed. With its small form factor and robust performance, the AT24C64 is a versatile solution for embedding non-volatile memory in electronic designs.

The AT24C64 is a 64-kilobit EEPROM chip commonly used for non-volatile storage. Equivalent products include the Microchip 24LC64, STMicroelectronics M24C64, and the Catalyst Semiconductor CAT24C64. These chips generally offer similar features, including I2C interface and comparable voltage and speed ratings. It’s important to verify specifications such as voltage range, operating temperature, and write cycle endurance to ensure compatibility with your application.

The AT24C64 is an EEPROM (Electrically Erasable Programmable Read-Only Memory) device with an 8-pin configuration. Below is a concise description of its pin count and function:
1. A0, A1, A2 (Pins 1-3): These are address pins used to set the hardware address of the device, allowing up to eight devices to be connected on the same I²C bus by configuring these pins differently.
2. VSS (Pin 4): This is the ground pin for the device.
3. SDA (Pin 5): The Serial Data pin is used for bidirectional communication between the EEPROM and the I²C bus controller. It acts as both input and output.
4. SCL (Pin 6): The Serial Clock pin is used to synchronize data transfer between the EEPROM and the controller.
5. WP (Pin 7): The Write-Protect pin is used to enable or disable write operations. When connected to VCC, the entire memory is write-protected.
6. VCC (Pin 8): This is the power supply pin for the device, typically connected to a 2.7V to 5.5V power source.
These pins facilitate the integration of the AT24C64 into microcontroller-based systems for storage and retrieval of data.
