• Supports burst mode operation for high-performance sequential data access
• Includes self-timed write cycles with global write control and byte write enable capabilities
• Features power-down functionality controlled by the ZZ input pin

Applications

• High-speed digital signal processing systems
• Network communication equipment requiring fast buffer memory
• Industrial automation controllers

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as historical records indicate non-compliance for some variants. Check for end-of-life notices and obsolescence announcements prior to procurement. Ensure packaging specifications match design requirements.

Selection Notes

Select this component for applications requiring synchronous SRAM with 18-bit data width. Verify that the system operates at 3.3V logic levels. Consider the 100-pin TQFP package constraints for PCB layout. Evaluate thermal performance within the specified operating temperature range.
