STMicroelectronics M27C512-90C6 EPROM

The M27C512-90C6 is a high-speed 512 Kbit EPROM (Erasable Programmable Read-Only Memory) produced by STMicroelectronics, a leader in the semiconductor industry. This integrated circuit is designed for applications where reliable and durable non-volatile memory storage is essential. With its 64K x 8 bit structure, this EPROM provides ample storage for firmware, bootstrap code, and other critical data that must be preserved across power cycles.

Key Features

• Memory Capacity: 512 Kbit (64K x 8)
• Access Time: 90 ns, enabling fast read operations and quick access to stored data.
• Package: The M27C512-90C6 comes in a convenient 28-pin Ceramic DIP (Dual In-line Package), offering robust physical protection and easy integration into a wide range of hardware designs.
• Single 5V Power Supply: Operates on a single 5V power supply, simplifying power management in the system design.
• Programming Voltage: 12.5V, which is standard for EPROM technology, ensuring compatibility with common programming equipment.
• Temperature Range: The device is specified for a wide operating temperature range, making it suitable for use in various environments.

Programming and Erasure

The M27C512-90C6 can be electrically programmed using a compatible EPROM programmer. It supports byte-by-byte programming, which is ideal for updating specific sections of the memory without affecting the entire array. For erasure, the device requires exposure to ultraviolet (UV) light, which clears the stored data, allowing the EPROM to be reused. The transparent quartz window on the top of the package facilitates this process, providing a pathway for UV light to reach the silicon die.

Applications

Thanks to its reliability and flexibility, the M27C512-90C6 is suitable for a wide array of applications, including but not limited to:

• Embedded systems
• Microcontroller-based applications
• Industrial control systems
• Telecommunication equipment
• Automotive electronics
• Medical devices

In summary, the M27C512-90C6 from STMicroelectronics is a versatile and reliable choice for applications requiring a robust non-volatile memory solution. Its fast access time, ease of integration, and proven technology make it a preferred choice for designers and engineers across various industries.
