The AM28F020-200JC is a 2-Megabit (256K x 8) CMOS Flash memory device manufactured by Advanced Micro Devices (AMD). The '200' in the part number indicates a 200ns access time, slower than the AM28F020-150EC. The 'JC' typically specifies the package type and temperature range.

Applications

• Embedded systems for code and data storage
• BIOS storage in older computer systems
• Industrial control systems
• Networking equipment
• Data logging devices

Features

• 2-Megabit (256K x 8) organization
• Access time: 200 ns
• Single 5V power supply
• Sector Erase Capability
• In-system programmability
• TTL Compatible Inputs/Outputs
• Low power consumption

Benefits

• Non-volatile storage, retaining data even when power is off
• Electrically erasable and programmable for easy updates
• In-system programmability allows for firmware updates without device removal
• Sector erase enables selective data modification
• Low power consumption is suitable for portable devices

Additional Details

The AM28F020-200JC is a reliable flash memory solution for a variety of embedded applications. Its electrical erase and program capabilities provide flexibility for updating firmware or data in the field. The sector erase function allows portions of the memory to be erased and reprogrammed without affecting other data. The single 5V power supply simplifies system design.

While its 200ns access time is slower than some other flash memory devices, it is adequate for many embedded applications where high-speed access is not critical. The in-system programmability simplifies maintenance and upgrades.

The device is typically available in a PDIP (Plastic Dual In-line Package), PLCC (Plastic Leaded Chip Carrier) or TSOP (Thin Small Outline Package). It is crucial to handle the device with care to prevent electrostatic discharge (ESD) damage. Follow manufacturer's programming guidelines for reliable operation.
