Overview
The IDT71V3577S80BGI is a high-speed Synchronous ZBT SRAM organized as 128K x 36, providing a total storage capacity of 4.5 Mbit. It operates with a maximum clock frequency of 100 MHz and features an access time of 8 ns. The device utilizes a parallel interface and supports a supply voltage range of 3.135 V to 3.465 V. It is housed in a 119-pin PBGA package measuring 14x22 mm.
Feature Summary
- Supports high-performance system speeds through synchronous operation at up to 100 MHz.
- Features Zero Bus Turnaround (ZBT) technology to eliminate dead cycles between write and read operations.
- Includes an internal burst address counter that accepts the first cycle address from the processor to initiate sequential data access.
Applications
- High-speed cache memory systems
- Network infrastructure equipment
- Telecommunications hardware
Procurement Notes
Verify component authenticity due to potential availability issues. Confirm RoHS compliance status as some variants may not meet current environmental standards. Check for moisture sensitivity level requirements during handling. Ensure the specific suffix matches design specifications. Validate lead times as production status may vary.
Selection Notes
Select this component for designs requiring fast synchronous memory with low latency. Consider the 128K x 36 organization for wide data path applications. Evaluate the 119-PBGA package constraints for PCB layout. Compare against newer generations if power consumption or pin count optimization is critical.
Part Context
This part belongs to the IDT 71V3577 family of Synchronous ZBT SRAMs. It shares architectural similarities with other devices in the series, such as the 71V3579, which offers different memory organizations like 256K x 18. These components are designed for embedded applications demanding high throughput and deterministic timing.
Replacement Considerations
The 71V3577S80BGI is obsolete. A confirmed substitute is the 71V3577S80BGI8. Verify pin compatibility and electrical characteristics before integration.
