IDT71V3557SA85BQGI

Memory IC Overview

The IDT71V3557SA85BQGI is a synchronous static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics. It features a storage capacity of 4.5 Mbit, organized as 128K words by 36 bits. The device supports parallel interface operation with an access time of 8.5 ns and a maximum clock frequency of 87 MHz. It operates within a supply voltage range of 3.135 V to 3.465 V and has a maximum power current of 180 mA. The component is housed in a 165-CABGA package measuring 13x15 mm.

Memory IC Feature Summary

Synchronous Single Data Rate (SDR) Zero Bus Turnaround (ZBT) architecture for high-performance data transfer
Flowthrough output mode providing immediate data availability upon address presentation
Self-timed write cycle controlled by global write control and byte write enable signals

Memory IC Applications

High-speed data buffering in telecommunications equipment
Cache memory implementation in network processing systems

Memory IC Procurement Notes

Verify the specific suffix BQGI against the manufacturer's official datasheet to confirm pinout compatibility and RoHS status. Confirm lead-free compliance requirements. Check for obsolescence notices or production lifecycle changes directly from Renesas documentation before finalizing procurement plans.

Memory IC Selection Notes

Select this component when a 36-bit wide synchronous SRAM interface is required. Ensure the system design accommodates the 165-pin CABGA package dimensions. Verify that the 8.5 ns access time meets the timing constraints of the target application bus speed.

Memory IC Part Context

This part belongs to the IDT 71V3557 family of synchronous ZBT SRAMs. It shares architectural similarities with other members like the IDT71V3557S75BQ but differs in access speed and package type. The family is designed for applications requiring fast, burst-mode memory access with low standby power consumption.
