• Video cards
• Industrial control systems

Features

• Capacity: 16Mbit (4M x 4)
• Organization: 4M words x 4 bits
• Access Time: -6, indicating an access time of 60ns (nanoseconds)
• Interface: Standard asynchronous DRAM interface
• Package: SOJ (Small Outline J-lead) package for surface mount assembly
• Refresh: Requires periodic refresh cycles to maintain data integrity
• Voltage: Operates on a 5V power supply

Benefits

• Cost-Effective Memory Solution: DRAM technology offers a balance between performance and cost.
• Moderate Speed: 60ns access time provides adequate speed for many applications.
• Simplified Integration: Standard DRAM interface simplifies design-in.
• Widespread Availability: Established DRAM technology with broad market support.
• Compact Form Factor: SOJ package enables efficient use of board space.

Additional Details

The HM5116400S-6 utilizes a standard asynchronous DRAM interface, meaning that data transfers are not synchronized to a clock signal, unlike SDRAM. Refresh cycles are necessary to prevent data loss due to the charge leakage inherent in DRAM cells. The 60ns access time indicates the time required for the memory to output valid data after an address is applied. Detailed specifications regarding refresh timings, power consumption, and operating conditions are available in the official Hitachi datasheet for the HM5116400S-6.
