Description

The 24LC256-I/P is a 256-Kilobit (32KB) electrically erasable programmable read-only memory (EEPROM) from Microchip Technology. It operates on a wide voltage range from 2.5V to 5.5V, making it versatile for various applications. The device uses the I2C (Inter-Integrated Circuit) bus protocol for communication, allowing multiple devices to be connected in parallel while minimizing pin usage.
Key features include a 400 kHz clock frequency for fast data transfer, up to 1 million erase/write cycles, and data retention of over 200 years. The 24LC256-I/P supports both byte-level and page-level data writing, with a page size of 64 bytes, optimizing data handling efficiency. Its DIP (Dual In-line Package) form factor makes it suitable for through-hole mounting in traditional circuit boards.
With its low-power consumption, the 24LC256-I/P is ideal for portable and battery-powered devices, data logging, and memory expansion in embedded systems. The EEPROM's reliability and durability make it a popular choice for applications requiring non-volatile memory storage.

Pinout

The 24LC256-I/P is a 256 Kbit (32 Kbyte) I²C EEPROM manufactured by Microchip Technology. It has an 8-pin configuration and operates with a two-wire serial interface. Here are the functions of each pin:
1. A0, A1, A2 (Pins 1-3): These are address pins used to set the I²C device address, allowing up to eight 24LC256 devices on the same bus.
2. VSS (Pin 4): This is the ground pin.
3. SDA (Pin 5): The Serial Data line used for both input and output; this pin is open-drain and requires a pull-up resistor.
4. SCL (Pin 6): The Serial Clock line; this pin is used to synchronize the data transfer between the microcontroller and the EEPROM.
5. WP (Pin 7): The Write-Protect pin; when connected to VCC, write operations are disabled, providing hardware data protection.
6. VCC (Pin 8): The power supply pin, typically operating at 2.5V to 5.5V.
This configuration allows for efficient data storage and retrieval in embedded systems.
