• It features fully static operation, meaning no clock or refresh cycles are required.
• The device is TTL-compatible and supports asynchronous operation.
• Ideal for embedded systems, industrial controls, networking, and telecommunications.

Features:

• High-speed access time: 35ns
• Low power consumption:
• Active: 40mA (typical)
• Standby: 10µA (typical, CMOS level)
• Directly replaces AS6C1008 and similar SRAMs
• Fully static operation (no refresh needed)
• Tri-state outputs for bus compatibility
• Single 5V power supply
• Industrial-grade temperature range available

This SRAM is commonly used in legacy systems, industrial automation, and other applications requiring reliable, fast-access memory.
