The M95256-DRMF3TG/K is a high-performance 256-Kbit EEPROM (Electrically Erasable Programmable Read-Only Memory) from the reputable semiconductor manufacturer, STMicroelectronics. This compact memory device is designed for a wide range of applications that require reliable data storage and retrieval with the convenience of electrical erasability.

The M95256-DRMF3TG/K operates over a wide voltage range from 2.5V to 5.5V, making it versatile for use in various electronic circuits and systems. Its 256-Kbit capacity is organized as 32,768 x 8 bits, which can be accessed through a high-speed SPI (Serial Peripheral Interface) bus. The SPI bus ensures compatibility with a broad array of microcontrollers and is known for its simplicity and efficiency in enabling fast data transfers.

One of the standout features of this EEPROM is its fast write cycle time, which is typically 5 ms for a full write cycle, including the auto-erase and auto-program functions. This quick write time is essential for applications that require frequent data updates without significant delays.

Data integrity is a critical aspect of any memory device, and the M95256-DRMF3TG/K addresses this with its 40-year data retention capability and support for more than 1 million write cycles per byte. These features ensure that data is preserved over an extended period, even under frequent usage conditions.

Additional functionalities include a Write Protect (WP) pin to prevent accidental data overwrite and a Hold pin to pause serial communication without resetting the serial sequence. This level of control is crucial for complex systems where data integrity during multi-tasking operations is paramount.

STMicroelectronics has packaged the M95256-DRMF3TG/K in an 8-pin ultra-thin small outline package (TSSOP), which is suitable for space-constrained applications. This miniature form factor, combined with the low-power consumption and high reliability, makes the M95256-DRMF3TG/K an excellent choice for portable devices, industrial controls, healthcare equipment, and other sophisticated electronic products.
