概要
Description
The device features a wide operating voltage range, typically from 1.7V to 5.5V, ensuring compatibility with various systems. It supports standard and fast I²C modes, with clock frequencies up to 1 MHz. The 24AA02E48T-I/OT is designed for industrial temperature ranges (-40°C to +85°C), making it suitable for harsh environments.
Key applications include networking equipment, IoT devices, and any system requiring a pre-programmed EUI-48 address. Its compact packaging options, typically 8-pin SOIC, TSSOP, or PDIP, allow for flexible design integration. The device’s small footprint, low power consumption, and reliable EEPROM technology make it a robust choice for embedded applications.
Equivalent
1. Atmel/Microchip AT24MAC402: Another EEPROM with a pre-programmed MAC address.
2. STMicroelectronics ST25TA02K: An NFC tag IC with similar memory and functionality.
3. NXP Semiconductors UCODE series: Offers unique IDs for identification applications, though not direct EEPROM.
Consider compatibility with your specific application requirements when choosing replacements.
Features
1. EEPROM Memory: It offers 2 Kbit (256 x 8) of Electrically Erasable Programmable Read-Only Memory, allowing for non-volatile storage.
2. Unique MAC Address: The device contains a globally unique 48-bit node address (MAC address), useful for network interfaces.
3. Communication Protocol: It supports I²C bus protocol, enabling easy integration with microcontrollers and other I²C-compatible devices.
4. Operating Voltage: It operates over a wide voltage range from 1.7V to 5.5V.
5. Low Power Consumption: The device features low standby current and operates efficiently, making it suitable for battery-powered applications.
6. Temperature Range: It is rated for operation in the industrial temperature range of -40°C to +85°C.
7. Write Protection: The EEPROM includes a write protection feature to prevent unauthorized data alterations.
8. Package Options: Available in standard packaging options like SOIC, TSSOP, and UDFN.
These features make it suitable for use in applications needing reliable, low-power memory and unique identifiers, such as in networking equipment and embedded systems.
Pinout
The 24AA02E48T-I/OT comes in an 8-pin package, with the following pin configuration:
1. VCC: Power supply pin.
2. GND: Ground reference.
3. WP: Write Protect pin; when connected to VCC, the entire memory array is write protected.
4. SDA: Serial Data; bidirectional for transferring addresses and data.
5. SCL: Serial Clock; input for clock synchronization.
6. A0, A1, A2: Device address inputs—these are typically hardwired or used to select the device address.
This EEPROM is ideal for use in applications where a unique, factory-programmed MAC address is required, reducing the time and effort associated with managing MAC addresses in the field.
