Memory IC Overview

The IDT71V3558S100PFGI is a 4.5Mb synchronous single data rate zero bus turnaround SRAM manufactured by Renesas Electronics Corporation. Organized as 256K x 18, this volatile memory IC supports parallel interfaces with a maximum clock frequency of 100 MHz and an access time of 5 ns. It operates within a supply voltage range of 3.135V to 3.465V and is housed in a 100-TQFP (14x14) surface-mount package. The device functions at temperatures between 0°C and 70°C.

Memory IC Feature Summary

Supports high-speed synchronous operations with zero bus turnaround capability for efficient bidirectional data transfer.
Features pipelined outputs to eliminate dead bus cycles during read-to-write or write-to-read transitions.
Designed for low power consumption using 3.3V CMOS technology.

Memory IC Applications

High-performance computing systems requiring fast data buffering
Network infrastructure equipment needing rapid packet processing
Industrial automation controllers demanding reliable real-time memory

Memory IC Procurement Notes

This component has reached end-of-life status and is officially discontinued by the manufacturer. Procurement must rely on existing stock from authorized distributors or secondary market suppliers. Verify RoHS compliance status carefully, as the product documentation indicates it does not meet current RoHS specifications. Ensure compatibility with legacy system designs before sourcing replacement units.

Memory IC Selection Notes

Select this part when designing systems requiring 4.5Mb capacity with 18-bit word width and 100MHz synchronous performance. It is suitable for applications needing ZBT SRAM characteristics to maximize bus efficiency. Consider alternative packages like CABGA if higher pin counts are required, or verify if lower speed variants suffice for cost-sensitive designs.

Memory IC Part Context

Part of the 71V3558 family of 3.3V Synchronous ZBT SRAMs, which includes variants such as 71V3558SA100BQ8 in different packages. This series is engineered for high-throughput applications where minimizing bus turnaround latency is critical. The IDT branding reflects its origin prior to Renesas acquisition.
