• Embedded systems requiring simultaneous bidirectional data flow

Memory IC Procurement Notes

Verify current manufacturing status as this component may be subject to discontinuation notices. Confirm package availability and moisture sensitivity levels prior to ordering. Ensure compatibility with existing board layouts regarding the 208-pin CABGA footprint. Check for updated RoHS compliance documentation if required for specific regional regulations.

Memory IC Selection Notes

Select this component when simultaneous read/write operations are required across two distinct interfaces. Consider the 166 MHz speed grade for applications demanding high throughput. Verify that the 3.3V I/O voltage levels match the host system requirements. Evaluate the need for JTAG support if board-level testing infrastructure is utilized.

Memory IC Part Context

This part belongs to the 70T3339/19/99 series of synchronous dual-port SRAMs. It shares architectural similarities with the 70V3399S166BFG but differs in specific electrical characteristics and package options. The series is optimized for applications involving unidirectional or bidirectional data bursts.

Memory IC Replacement Considerations

Direct substitutes include variants within the same family such as the 70T3319S166BF or 70V3399S166BFG, provided pinouts and electrical specifications align. Verify functional equivalence regarding interleaved I/Os and control signals before implementation.
