Pinout
The 24LC256T-E/MS is a 256 Kbit I2C-compatible EEPROM (Electrically Erasable Programmable Read-Only Memory) with a 8-pin configuration. The pin count and their functions are as follows:
1. VCC (Pin 1): Power supply pin (typically +2.5V to +5.5V).
2. GND (Pin 2): Ground pin.
3. SDA (Pin 3): Serial Data Line for data communication.
4. SCL (Pin 4): Serial Clock Line for synchronization of data transfers.
5. WP (Pin 5): Write Protect pin; when high, it protects the memory from being written.
6. A0 (Pin 6): Address pin to set the least significant bit of the I2C address.
7. A1 (Pin 7): Address pin to set the middle bit of the I2C address.
8. A2 (Pin 8): Address pin to set the most significant bit of the I2C address.
This device allows for 32 pages of 8 bytes each for data storage, making it suitable for various applications requiring non-volatile memory.
