71V547S100PFGI8

Overview

The 71V547S100PFGI8 is a synchronous static random access memory (SRAM) device manufactured by Renesas Electronics. It features a storage capacity of 4 Mbit organized as 128 k x 36 bits. The component supports a maximum clock frequency of 66 MHz with an access time of 10 ns. It operates on a parallel interface and requires a supply voltage between 3.135 V and 3.465 V, with a maximum power current of 200 mA. The device is housed in a TQFP-100 surface-mount package and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Supports synchronous single data rate (SDR) operations for high-speed data transfer
• Provides 36-bit wide data output capability for efficient bus utilization
• Features flow-through architecture for predictable timing performance

Applications

• High-performance computing systems requiring fast memory access
• Network infrastructure equipment utilizing parallel interfaces
• Industrial control systems operating within commercial temperature ranges

Procurement Notes

Verify the specific suffix PFGI8 to confirm the TQFP-100 package and industrial/commercial grade designation. Ensure compatibility with 3.3V logic levels and check moisture sensitivity handling requirements during assembly. Confirm that the 1000-unit reel packaging aligns with production volume needs. Validate lead times as manufacturing cycles may vary.

Selection Notes

Select this component when a 36-bit data width is required for system bus architectures. The 10 ns access time suits applications needing moderate speed synchronous memory. Consider the TQFP-100 footprint for PCB layout constraints. Verify that the 66 MHz clock limit meets the target system's timing specifications before integration.

Part Context

This part belongs to the 71V547 series of synchronous SRAMs from Renesas. It is functionally related to legacy IDT products, often sharing pinouts and specifications. The device serves as a volatile memory solution for embedded applications where fast read/write cycles are essential but do not require the complexity of DRAM controllers.
