71V3559S75PFGI

Memory IC Overview

The 71V3559S75PFGI is a synchronous single data rate (SDR) static random-access memory (SRAM) manufactured by Renesas Electronics. It features a storage capacity of 4.5 Mbit organized as 256K x 18 bits. The device supports parallel interface operation with a maximum access time of 7.5 ns and a maximum clock frequency of 100 MHz. It operates within a supply voltage range of 3.135 V to 3.465 V, with a maximum power supply current of 260 mA. The component is designed for surface-mount installation in a TQFP-100 package and functions reliably across an industrial temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Supports synchronous SDR burst mode operations for high-speed data transfer
• Provides independent port control with separate address, data, and command lines
• Includes global write control and byte write enable capabilities for flexible data management

Memory IC Applications

• High-performance embedded systems requiring fast random access memory
• Industrial automation controllers needing reliable data buffering
• Telecommunications equipment utilizing synchronous memory interfaces

Memory IC Procurement Notes

Verify the specific suffix PFGI to confirm the TQFP-100 package type and industrial temperature grade. Ensure compatibility with 3.3V logic levels and check for RoHS compliance status through official documentation. Confirm availability as distribution channels may vary. Validate moisture sensitivity level requirements for surface-mount assembly processes before procurement.

Memory IC Selection Notes

Select this component when a 4.5 Mbit synchronous SRAM with 18-bit width is required. The 7.5 ns access time suits applications demanding moderate to high-speed data processing. The TQFP-100 package offers a balance between pin count and board space. Consider the 3.3V I/O compatibility with existing system buses. Evaluate thermal performance within the specified -40°C to +85°C operating range for environmental suitability.
