The AM27C64-200/BXA is a 64K (8K x 8) CMOS EPROM (Erasable Programmable Read-Only Memory) manufactured by AMD. This memory device is designed for applications requiring non-volatile storage of data and program code. It operates on a single +5V power supply and offers a relatively fast access time, making it suitable for various embedded systems and microprocessor-based applications.

Applications:

• Firmware storage in embedded systems
• Program storage for microcontrollers
• Boot loaders
• Character generators
• Lookup tables

Features:

• 64K (8K x 8) memory organization
• CMOS technology for low power consumption
• Fast access time (200ns)
• Single +5V power supply
• TTL compatible inputs and outputs
• Three-state output for OR-tying
• Programmable using standard EPROM programmers
• Erasable with ultraviolet light

Benefits:

• Non-volatile storage ensures data retention even when power is off.
• Fast access time allows for quick retrieval of stored information.
• Low power consumption makes it suitable for battery-powered applications.
• Easy programmability simplifies the development and prototyping process.
• TTL compatibility enables seamless integration with existing logic circuits.

Additional Details:

The AM27C64-200/BXA is typically packaged in a 28-pin DIP (Dual In-line Package). The device is erased by exposing it to ultraviolet light of a specific wavelength for a specified duration. After erasure, the memory can be reprogrammed with new data. The operating temperature range is typically from 0°C to +70°C. The EPROM is designed to withstand a certain number of erase/program cycles, ensuring reliability over its lifespan. The output enable (OE) and chip enable (CE) pins provide control over the output and device selection, respectively.
