STMicroelectronics M2716-1F1 EPROM

The M2716-1F1 is a vintage yet highly influential 16-kilobit Electrically Programmable Read-Only Memory (EPROM) chip produced by STMicroelectronics, a leader in semiconductor solutions. This EPROM is a testament to the evolution of memory technology and has played a crucial role in the development of early microprocessor-based systems.

Featuring a 16,384-bit (16Kb) storage capacity, the M2716-1F1 is organized as 2,048 words by 8 bits, making it suitable for storing firmware, boot code, or other small data sets that require long-term persistence without power. Its 24-pin dual in-line package (DIP) encapsulation ensures compatibility with a wide range of circuit board layouts and legacy systems.

One of the defining characteristics of the M2716-1F1 is its UV-erasable window, which allows the stored data to be erased by exposing the chip to ultraviolet light. This feature enables the chip to be reprogrammed and reused multiple times, making it a versatile choice for development and prototyping applications.

The M2716-1F1 operates with a single 5V power supply, which was standard for logic levels in the era of its production. It boasts fast access times, typically around 350 nanoseconds, allowing for efficient read operations. This is particularly impressive considering the technology of the time and reflects STMicroelectronics' commitment to high-performance memory solutions.

Programming the M2716-1F1 requires a special device called an EPROM programmer, which can provide the necessary voltage levels and programming sequences to store data onto the chip. Once programmed, the data remains reliable for years, with typical data retention figures quoted at a minimum of 10 years.

In summary, the STMicroelectronics M2716-1F1 EPROM is a piece of technological history that has paved the way for modern non-volatile memory solutions. Its robust design, ease of use, and reprogrammability have made it a favored choice for engineers and hobbyists alike who work with legacy systems or require a reliable storage medium for their applications.
