The NEC D43256AGU-10LL is a 262,144-bit (256K x 1) Dynamic Random Access Memory (DRAM) designed for temporary data storage in various electronic devices. As a DRAM, it requires continuous power and periodic refresh cycles to retain the data stored in its memory cells. This particular model is known for its low power consumption and relatively fast access time.

Applications

• Personal Computers: Used as main memory in older personal computer systems.
• Graphics Cards: Utilized in older graphics cards for frame buffer memory.
• Printers: Incorporated into printer memory for buffering print data.
• Industrial Control Systems: Integrated into industrial automation equipment.
• Embedded Systems: Suited for embedded applications requiring low-power memory solutions.

Features

• Capacity: 262,144 bits (256K x 1 organization).
• Access Time: 100ns (nanoseconds).
• Refresh Cycle: Requires periodic refresh cycles to maintain data.
• Power Consumption: Very low power consumption (indicated by the 'LL' suffix).
• Package: DIP (Dual In-line Package) or other similar package.
• Single 5V Supply: Operates on a single 5V power supply.

Benefits

• Very Low Power Consumption: The 'LL' suffix indicates extremely low power consumption, ideal for battery-powered or energy-sensitive applications.
• Fast Access Time: 100ns access time allows for quick data retrieval and storage.
• Cost-Effective: Provides a cost-effective memory solution.
• Easy Integration: The DIP package simplifies integration into existing systems.

Additional Details

The D43256AGU-10LL is a volatile memory device and loses its stored data when power is removed. The 'AGU' in the part number may indicate specific packaging or manufacturing details unique to NEC. The '-10' denotes the access time of 100 nanoseconds. The 256K x 1 organization means the memory is structured as 262,144 individual memory locations, each capable of storing one bit of data. The 'LL' suffix signifies an extremely low-power version compared to standard or 'L' versions, making it suitable for applications prioritizing energy efficiency. Proper handling is required to prevent electrostatic discharge (ESD) damage, and the correct refresh timing must be implemented to maintain data integrity. It's crucial to consult the manufacturer's datasheet for precise specifications and application notes.
