The AM27C010 is a 1 Megabit (128K x 8-bit) CMOS EPROM (Erasable Programmable Read-Only Memory) manufactured by Advanced Micro Devices (AMD). It is a non-volatile memory device that can be electrically programmed and erased using ultraviolet (UV) light.

Applications

• Embedded Systems: Used for storing firmware, boot code, and program code in embedded systems.
• Industrial Control Systems: Employed in programmable logic controllers (PLCs) and other industrial automation equipment.
• Computer Peripherals: Found in printer ROMs, video card BIOS, and other peripheral devices.
• Telecommunications Equipment: Utilized in network devices for storing configuration data and operating system code.
• Gaming Consoles: Used to store game code and system software in older gaming consoles.
• Medical Devices: Integrated into medical instruments for storing calibration data and program code.

Features

• 1 Megabit Capacity: Stores 1,048,576 bits of data (128KB).
• CMOS Technology: Low power consumption compared to NMOS EPROMs.
• UV Erasable: Can be erased using ultraviolet light, allowing for reprogramming.
• Fast Access Time: Provides quick access to stored data. Specific access times varied by speed grade (e.g., 150ns, 200ns).
• Single 5V Supply: Operates on a single 5V power supply.
• JEDEC Standard Pinout: Follows the JEDEC standard pinout for EPROMs, ensuring compatibility with other devices.

Benefits

• Non-Volatile Storage: Retains data even when power is removed.
• Reprogrammable: Can be erased and reprogrammed multiple times, allowing for firmware updates and corrections.
• High Reliability: Provides reliable data storage for critical applications.
• Easy to Use: Simple programming and erasing procedures.
• Cost-Effective: Provides a cost-effective solution for storing firmware and program code.

Additional Details

The AM27C010 is typically programmed using a dedicated EPROM programmer. The device must be exposed to UV light of a specific wavelength (typically 253.7 nm) through a quartz window to erase the data. The erased state is all bits set to '1'. Detailed information regarding programming voltages, erasing times, and operating temperature ranges can be found in the manufacturer's datasheet.
