Descriptions:

• The IS61LV25616AL-10TL is a low-voltage, high-performance SRAM designed for applications requiring fast access times and low power consumption.
• It features a 16-bit wide data bus, making it suitable for high-bandwidth systems.
• The device supports asynchronous operation with separate byte controls (UB, LB) for flexible data handling.
• It is fully static, meaning no refresh cycles are required.

Features:

• High-Speed Access: 10 ns maximum access time.
• Low Power Consumption:
• Active current: 80 mA (typical)
• Standby current: 10 µA (typical)
• 3.3V Single Power Supply (compatible with LVTTL/LVCMOS).
• Tri-State Outputs for bus compatibility.
• Byte Control (UB/LB) for independent upper/lower byte access.
• Industrial Temperature Support (-40°C to +85°C).
• TSOP-II Package for space-efficient PCB designs.

This SRAM is commonly used in networking, telecommunications, embedded systems, and high-performance computing applications where fast and reliable memory access is critical.
