The AM27C512-120/BXA is a 512K (64K x 8) CMOS EPROM (Erasable Programmable Read-Only Memory) supplied by Rochester Electronics. The '120' indicates an access time of 120ns, and 'BXA' is a specific package or processing code. As Rochester Electronics specializes in continuing the supply of discontinued parts, this EPROM is likely one they currently offer.

Applications

• Firmware storage in embedded systems
• Program storage in microcontrollers
• Boot loaders
• Data storage in electronic devices
• Configuration memory for programmable logic devices (PLDs)

Features

• 512K (64K x 8) memory organization
• CMOS technology for low power consumption
• 120ns access time
• Single 5V power supply
• TTL compatible inputs and outputs
• Programmable using standard EPROM programmers
• Erasable with ultraviolet (UV) light

Benefits

• Non-volatile storage: Data is retained even when power is removed.
• Low power consumption: Suitable for battery-powered devices.
• Fast access time: Enables quick retrieval of stored data.
• Easy to program: Can be programmed using readily available EPROM programmers.

• High reliability: Proven technology for reliable data storage.

Additional Details

The AM27C512-120/BXA operates on a single 5V power supply and is typically found in a 28-pin DIP or similar package. The 120ns access time allows for faster data retrieval compared to slower EPROMs. Being CMOS, it consumes significantly less power than older NMOS EPROMs. It is programmed using an EPROM programmer and erased using UV light. Rochester Electronics' involvement indicates continued availability and support for this part, which is crucial for maintaining legacy systems.
