Overview
The IDT71V3577S85PFG is a high-speed Synchronous ZBT SRAM organized as 128K x 36, providing 4.5 Mbit of storage capacity. It operates with an access time of 8.5 ns and supports clock frequencies up to 87 MHz. The device utilizes a parallel interface and functions on a 3.3V power supply (3.135V to 3.465V). It is housed in a 100-pin LQFP package (14x20 mm) and is designed for surface mount installation.
Feature Summary
- Supports high-performance system speeds through synchronous burst operations
- Eliminates dead cycles between write and read operations via ZBT architecture
- Features flow-through output architecture without registers in the data output path
Applications
- High-speed cache memory systems
- Network infrastructure equipment
- Telecommunications base stations
Procurement Notes
Verify component authenticity by checking manufacturer markings against official datasheets. Confirm package integrity and pin alignment prior to assembly. Ensure ESD protection protocols are followed during handling. Validate voltage levels match the 3.3V specification before powering the circuit.
Selection Notes
Select this component for applications requiring fast synchronous access with low latency. The 128K x 36 organization suits wide-data bus architectures. Verify that the 100-pin LQFP footprint matches the PCB design constraints. Ensure the operating temperature range meets the specific environmental requirements of the target application.
Part Context
This part belongs to the IDT 71V3577/79 series of 3.3V Synchronous ZBT SRAMs. It shares architectural similarities with other members of the family but differs in memory organization and speed grades. The series is characterized by its ability to provide four cycles of data for a single address presentation.
Replacement Considerations
Publicly confirmed substitute part numbers for this specific component were not identified in the provided documentation.
