STMicroelectronics M27C4001-45XF1 EPROM

The M27C4001-45XF1 is a high-speed 4 Mbit (4,194,304 bits) EPROM (Erasable Programmable Read-Only Memory) from STMicroelectronics, renowned for its quality and reliability in the semiconductor industry. This particular model offers a large storage capacity suitable for applications that require data or code storage, such as embedded systems, personal computers, and various electronic devices.

Featuring an access time of 45ns, the M27C4001-45XF1 ensures swift data retrieval, making it an ideal choice for performance-critical applications. The device operates within a single 5V power supply, which is standard in the industry, thus simplifying the power design for the system it is incorporated into.

The memory is organized as 512K x 8 bits, which allows for efficient data management and easy access to stored information. The EPROM is packaged in a 32-pin Ceramic DIP (Dual In-line Package), which provides robust physical protection and offers reliable connectivity for through-hole mounting on printed circuit boards (PCBs).

One of the key features of the M27C4001-45XF1 is its programmability. Users can erase the stored data with exposure to ultraviolet (UV) light, and then reprogram the memory with new data. This capability makes the device extremely versatile for prototyping, testing, and iterative development processes. Additionally, the EPROM's non-volatility ensures that the data remains intact even when the power is turned off.

STMicroelectronics has equipped this EPROM with various modes such as standby mode to reduce power consumption when the device is not in active use. It also supports a temporary electronic chip identification mode that allows for device recognition and verification, enhancing system security and integrity.

In summary, the M27C4001-45XF1 from STMicroelectronics is a robust and reliable storage solution, suitable for a wide range of applications that demand a large memory capacity, fast access times, and the flexibility of data erasure and reprogramming.
