STMicroelectronics M27C1001-45C1 EPROM

The M27C1001-45C1 is a high-performance 1Mbit (1,048,576 bits) UV erasable and programmable read-only memory (EPROM) component from STMicroelectronics. It is designed to offer a flexible and cost-effective solution for a wide range of applications where reliable and non-volatile data storage is essential. With a 45 ns access time, this EPROM provides fast data retrieval, making it suitable for high-speed microprocessor systems.

Constructed with STMicroelectronics' innovative and reliable CMOS technology, the M27C1001-45C1 boasts low power consumption, with a typical standby current of 100 µA, which is ideal for energy-saving applications. Its single 5V power supply requirement simplifies the power design for electronic systems, and its programming voltage (VPP) of 12.75V is standard for EPROM devices of this class.

The M27C1001-45C1 comes in a compact 32-pin Ceramic Dual In-line Package (CDIP) or Plastic Leaded Chip Carrier (PLCC), providing robust physical protection and ease of integration into various circuit boards. The device's organization is 128K x8 bits, which allows for efficient data management and addressing.

For programming, the M27C1001-45C1 features two-line control functions: Chip Enable (E) and Output Enable (G). These functions ensure device security and prevent inadvertent data corruption during the high-voltage programming process. After programming, the EPROM can be erased by exposure to UV light, allowing it to be reused and reprogrammed multiple times, which is especially beneficial for prototyping and testing phases.

STMicroelectronics provides a guarantee for data retention with the M27C1001-45C1, ensuring that data remains intact for a minimum of 10 years after programming. This long-term reliability is crucial for applications that require stable and persistent data storage over extended periods.

In summary, the M27C1001-45C1 from STMicroelectronics is a versatile and reliable EPROM solution that offers fast access time, low power consumption, and the ability to be erased and reprogrammed. Its robust packaging and data retention capabilities make it a suitable choice for a diverse array of applications, including embedded systems, telecommunications, computing, and industrial controls.
