The MCM68708L is an 8K (1K x 8) EPROM (Erasable Programmable Read-Only Memory) manufactured by Freescale Semiconductor (formerly Motorola, now NXP). It is a non-volatile memory device that can be electrically programmed and erased, making it suitable for storing firmware, boot code, and other data that needs to be retained even when power is off.

Applications:

• Firmware storage in embedded systems
• Boot code storage in microcontrollers
• Program storage for early microcomputers
• Data storage in programmable logic controllers (PLCs)
• Industrial control systems

Features:

• 8K (1K x 8) memory organization
• Erasable and reprogrammable
• Single 5V power supply
• TTL compatible inputs and outputs
• Fast access time (typically 450 ns)
• Three-state outputs for bus interfacing
• Available in a DIP package

Benefits:

• Non-volatile storage of data
• Easy to program and erase
• Compatible with standard TTL logic
• Suitable for a wide range of applications
• Reliable data storage

Technical Specifications:

The MCM68708L features an 8K memory organization, with 1024 bytes of storage. It requires a single 5V power supply for operation and is compatible with standard TTL logic levels. The typical access time is 450 ns, allowing for fast data retrieval. The device has three-state outputs, which enable it to be easily interfaced with microprocessor and microcontroller buses. The MCM68708L is available in a DIP (Dual In-line Package) package, which is easy to handle and socket.

Programming the MCM68708L requires specialized equipment, such as an EPROM programmer. The device is erased by exposing it to ultraviolet (UV) light through a quartz window on the top of the package. Once erased, the device can be reprogrammed with new data. The MCM68708L is commonly used in embedded systems for storing firmware and boot code. It is also used in older microcomputers and industrial control systems for program storage.

The non-volatile nature of EPROM makes it ideal for applications where data must be retained even when power is lost. The ability to erase and reprogram the device allows for easy updating of the stored data. The MCM68708L is a reliable and versatile memory device that is suitable for a wide range of applications.
