STMicroelectronics M27C4001-12C1 EPROM

The M27C4001-12C1 is a high-speed 4 Mbit (4,194,304 bits) EPROM (Erasable Programmable Read-Only Memory) from the renowned semiconductor manufacturer STMicroelectronics. This memory device is designed for applications that require fast access times and a non-volatile storage solution where data can be electrically erased and reprogrammed. It is particularly well-suited for use in embedded systems, microcontroller units, and various types of programmable logic devices where reliable and durable storage of firmware or software is essential.

With an access time of 120 ns, the M27C4001-12C1 offers quick data retrieval, which is crucial for high-performance computing tasks. The device operates within a single 5V power supply, making it compatible with a wide range of existing circuits and systems. Additionally, the EPROM comes in a convenient 32-pin DIP (Dual In-line Package), which ensures easy integration into socketed or PCB-mounted applications.

The M27C4001-12C1 features an organized memory array of 512K x 8 bits, allowing for a straightforward and efficient data management scheme. Its transparent lid allows for exposure to ultraviolet light to erase data, providing a way to recycle the chip for new programs and data sets. This characteristic is particularly useful for prototyping and testing environments where code frequently needs updating.

STMicroelectronics has designed the M27C4001-12C1 with several modes of operation, including read, program, and erase modes, adding to its flexibility. The device also incorporates programming and erase times that are competitive within the industry, ensuring quick turnaround during development cycles.

For data protection, the M27C4001-12C1 includes a feature that allows the user to define a block of memory as 'read-only,' which can prevent accidental overwriting or modification of critical code segments. This is especially important for the integrity of system-critical applications.

In summary, the M27C4001-12C1 from STMicroelectronics is a robust, reliable, and versatile memory solution that meets the needs of a wide array of electronic applications. Its combination of speed, power efficiency, and programming flexibility makes it an excellent choice for designers looking to leverage high-quality non-volatile memory in their products.
