24LC21AT-I/SN Typical application Circuitry

24LC21AT-I SN

An integrated circuit line of electrically erasable programmable read-only memory (EEPROM) is the 24LC series, which contains the 24LC21AT-I/SN. These devices are designed for storing data that must be preserved during power-off scenarios, making them ideal for applications that require non-volatile memory. The 24LC21AT-I/SN, in particular, offers a compact, reliable solution for data storage with the convenience of a serial interface for communication, typically using the I²C protocol. This model is tailored for applications that need a small amount of storage, such as storing configuration settings, calibration data, or small application data, where the ability to update content is necessary after the device has been deployed.

1. Operating Voltage: The 24LC21AT-I/SN operates within a voltage range of 2.5V to 5.5V, making it versatile for use in both 3.3V and 5V systems. This broad operating voltage range facilitates integration into a wide array of electronic systems without necessitating voltage level conversion, simplifying the design and reducing the overall component count.

2. Pin Configuration and Connectivity: This device is offered in an 8-pin SOIC (SN) package, with each pin assigned a specific function: 1. A0 (Address Input), 2. A1 (Address Input), 3. A2 (Address Input), 4. VSS (Ground), 5. SDA (Serial Data), 6. SCL (Serial Clock), 7. WP (Write Protect), 8. VCC (Power Supply). For integration into a circuit, VCC and VSS should be connected to the system's power supply and ground, respectively. The SDA and SCL pins are used for data and clock signals in accordance with the I²C protocol. The A0, A1, and A2 pins are address inputs that allow multiple devices to share the same I²C bus by assigning unique addresses to each device. The WP pin is used to enable or disable write operations to the memory.

3. Circuit Integration Guidelines: To integrate the 24LC21AT-I/SN, connect the VCC pin to the power supply within the specified operating voltage range and VSS to the ground. The microcontroller or processor's associated I²C data and clock lines should be connected to the SDA and SCL pins. Pull-up resistors are normally needed on both lines in order for the system to function properly. The A0, A1, and A2 pins can be connected to VCC or VSS to set the device address, allowing for up to eight devices on the same I²C bus by configuring each with a unique address. The WP pin can be tied to VSS to allow writing to the device, or to VCC to protect the EEPROM from unintended writes.

4. Protection and Reliability: Adding pull-up resistors to the SDA and SCL lines ensures reliable communication over the I²C bus by maintaining a high level when the bus is idle. A decoupling capacitor close to the VCC and VSS pins is recommended to filter out power supply noise, enhancing the stability and reliability of the EEPROM operation.

5. Usage Considerations: The 24LC21AT-I/SN is adept at providing non-volatile memory storage in a variety of applications, from simple device configurations to storing user preferences or operational data that must be retained between power cycles. Its low power consumption and compact size make it particularly suitable for portable devices, consumer electronics, and other applications where space and power efficiency are critical.

The 24LC21AT-I/SN exemplifies the 24LC series' commitment to providing robust, easy-to-integrate memory solutions for a plethora of electronic applications. Its flexibility in operating voltage, straightforward I²C communication, and the ability to prevent unwanted writes with the WP pin make it a highly versatile component for designs requiring reliable non-volatile storage.
