The MBM27C1001A15Z is a 1 Mbit (128K x 8) EPROM (Erasable Programmable Read-Only Memory) manufactured by Fujitsu Electronics America, Inc. EPROMs are non-volatile memory devices that can be electrically programmed and erased using ultraviolet light. They were commonly used in embedded systems and applications where firmware needed to be updated occasionally.

Applications

• Embedded Systems
• Microcontroller Firmware Storage
• Industrial Control Systems
• Legacy Computer Systems
• BIOS Storage

Features

• 1 Mbit (128K x 8) Memory Capacity
• Erasable Programmable Read-Only Memory (EPROM)
• Fast Access Time (150ns)
• Single +5V Power Supply
• TTL Compatible Inputs and Outputs

Benefits

• Non-volatile storage, retaining data even without power.
• Reprogrammable, allowing for firmware updates.
• Fast access time for quick data retrieval.

Additional Details

The MBM27C1001A15Z has an access time of 150ns (nanoseconds), indicated by the '15' in the part number. It operates on a single +5V power supply. The memory array is organized as 131,072 bytes (128K x 8). Erasing the memory requires exposure to ultraviolet light through a quartz window on the package. The device is typically packaged in a DIP (Dual In-line Package). Consult the datasheet for detailed programming specifications, timing diagrams, and electrical characteristics.
