2. CAT24C256 by ON Semiconductor
3. M24C256 by STMicroelectronics
4. BR24G256 by ROHM Semiconductor
These equivalents offer similar functionality, such as 256Kb memory size and I2C interface, but ensure compatibility by checking specific electrical and timing specifications.
Features
1. Capacity: 32 KB of storage organized as 32,768 x 8.
2. Interface: I2C bus compatible, supports high-speed mode up to 1 MHz.
3. Voltage Range: Operates with a supply voltage from 2.5V to 5.5V.
4. Low Power: Features low power consumption with typical standby and active currents of 1 µA and 1 mA, respectively.
5. Page Write: Supports page write mode of up to 64 bytes.
6. Endurance: Offers over 1 million erase/write cycles with data retention of more than 200 years.
7. Package: Available in an 8-lead SOIC package.
8. Write Protection: Has a hardware write-protect pin to prevent inadvertent writes.
9. Temperature Range: Operates in a wide temperature range from -40°C to +85°C.
10. Reliability: Features robust data integrity with built-in hardware data protection.
These features make the 24LC256T-E/SN suitable for applications requiring reliable and low-power non-volatile memory.
Pinout
1. VCC (Pin 8): Power supply pin, typically 2.5V to 5.5V.
2. VSS (Pin 4): Ground pin.
3. SDA (Pin 5): Serial Data line; a bidirectional line for data transfer.
4. SCL (Pin 6): Serial Clock line; used for clock signal.
5. WP (Pin 7): Write Protect pin; when connected to VCC, write operations are disabled.
6. A0, A1, A2 (Pins 1, 2, 3): Device address pins; used to select one of up to 8 devices on the I²C bus.
The EEPROM supports standard I²C protocol for communication and is used to store data that needs to be retained when power is off. It is often used in applications like data logging, configuration settings storage, and other similar memory needs.
