The AM28F020-120PC is a 2 Mbit (256K x 8) Flash memory device manufactured by Advanced Micro Devices (AMD). This memory device provides non-volatile storage that can be electrically erased and reprogrammed. The '120' in the part number denotes an access time of 120 nanoseconds, which determines the speed at which the memory can be read.

Applications:

• Embedded Systems: Used to store firmware and configuration data in a variety of embedded applications, such as microcontrollers.
• Networking Equipment: Stores boot code and configuration settings in routers, switches, and network interface cards.
• Industrial Control Systems: Employed in programmable logic controllers (PLCs) and other industrial automation equipment.
• Telecommunications: Used in telecommunications equipment for storing configuration and control data.
• Consumer Electronics: Integrated into devices such as set-top boxes, digital cameras, and gaming consoles for firmware storage.

Features:

• 2 Mbit (256K x 8) Memory Organization: Provides a storage capacity of 2,097,152 bits organized as 262,144 bytes of 8 bits each.
• Fast Access Time: 120ns access time ensures quick and efficient data retrieval.
• Electrically Erasable and Programmable: Allows for in-system reprogramming, enabling firmware updates without removing the device.
