STMicroelectronics M24C256-BWN6TP EEPROM

The M24C256-BWN6TP is a 256-Kbit I²C-compatible EEPROM (Electrically Erasable Programmable Read-Only Memory) produced by STMicroelectronics. This high-performance memory module is designed to deliver a reliable and flexible storage solution for a wide range of applications. It is based on advanced CMOS technology, which ensures low power consumption and high endurance, making it suitable for sophisticated electronic systems.

The M24C256-BWN6TP offers a substantial 256 kilobits of storage, which is organized as 32,768 x 8 bits. This allows for efficient storage and retrieval of data, which is crucial for applications that require frequent updating of stored information without wearing out the memory cells. The device operates across a voltage range of 2.5V to 5.5V, providing compatibility with both low-voltage and standard logic levels, and is thus adaptable to various system designs.

This EEPROM features a two-wire I²C serial interface which supports a bidirectional data transfer protocol. The bus is designed to be highly efficient, requiring only two wires: one for serial data (SDA) and another for the serial clock (SCL). This simplifies the integration into existing designs and reduces the overall system complexity and cost.

One of the key advantages of the M24C256-BWN6TP is its support for byte and page write, with up to 64 bytes per page, allowing for faster data management and more efficient use of the memory. Additionally, the device has a self-timed write cycle with automatic clear, which includes a built-in erase and write cycle completion signal. This feature ensures data integrity and simplifies the task of managing write operations.

To protect user data, the M24C256-BWN6TP comes with write control features such as hardware and software write protection. The hardware protection is implemented by the Write Protect pin (WP), which can be used to lock the entire memory array or just a portion of it, depending on the application's needs. Meanwhile, the software write protection is achieved through the use of write protect instructions in the device's command set.

The M24C256-BWN6TP is available in a narrow 8-pin plastic DIP package, which is commonly used in the industry and is suitable for through-hole PCB mounting. Its standard package and compatibility with I²C make it an ideal choice for applications in the automotive industry, consumer electronics, medical devices, and industrial automation.
