STMicroelectronics M27C512-20XF1 Product Overview

The M27C512-20XF1 is a high-speed 512 Kbit EPROM (Erasable Programmable Read-Only Memory) manufactured by STMicroelectronics. This device is designed for applications that require fast access to non-volatile memory with the capability of being electrically erased and reprogrammed. It is particularly suitable for use in embedded systems, microcontroller-based applications, and various electronic products where reliable and durable storage of firmware or software is essential.

Key Features

• Memory Capacity: 512 Kbit (64K x 8)
• Access Time: 200 ns
• Single 5V Power Supply: The device operates on a single 5V power supply, making it compatible with many standard digital systems.
• Programming Voltage: 12.75V ± 0.25V
• Package: The M27C512-20XF1 comes in a 28-pin CFDIPW (Ceramic Frit-Seal Dual In-Line Package, Window) package, which provides environmental protection and allows for UV erasure of the memory content.
• Temperature Range: The device is specified for an extended temperature range from -40°C to +85°C, making it robust for use in harsh environments.

Applications

The versatility of the M27C512-20XF1 allows it to be used across a wide range of applications. Common uses include but are not limited to:

• Embedded systems and microcontrollers
• Automotive electronics
• Industrial control systems
• Telecommunication devices
