Technical Specifications

The IS24C32A-2DLI communicates via a 2-wire I2C serial interface, supporting both standard (100 kHz) and fast (400 kHz) modes. The device incorporates a self-timed write cycle, eliminating the need for external timing components. A page write mode allows for writing up to 32 bytes in a single operation, reducing the number of write cycles and improving overall system performance. The write protect feature, controlled by a dedicated pin, prevents accidental writes to the memory array, ensuring data integrity. The device operates over a wide temperature range, typically -40°C to +85°C, making it suitable for various industrial and commercial applications.

The IS24C32A-2DLI is a reliable and versatile EEPROM solution for applications requiring non-volatile memory storage with a simple serial interface.
