7005S35PFGI

Overview

The Renesas Electronics Corporation 7005S35PFGI is a high-speed, 64K-bit (8K x 8) dual-port static random-access memory (SRAM). It operates asynchronously with a maximum access time of 35 nanoseconds. The device supports a single 5V power supply within the 4.5V to 5.5V range and features TTL-compatible I/O levels. It is housed in a 64-pin Thin Quad Flat Package (TQFP) with a 14x14mm footprint and is rated for an industrial operating temperature range of -40°C to +85°C.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent reads from both ports.
• Integrated hardware semaphore signaling and port arbitration logic for master/slave configurations.
• Automatic power-down mode controlled by chip enable signals to minimize standby current.
• Supports battery backup operation with data retention down to 2V.

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded systems
• Data acquisition systems requiring concurrent host and peripheral access
• Industrial control networks utilizing master/slave port architectures

Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status as older batches may not meet current environmental directives. Validate package marking accuracy against official datasheet specifications. Ensure storage conditions adhere to moisture sensitivity level requirements prior to soldering.

Selection Notes

Select this component when asynchronous dual-port functionality is required for shared memory access. Consider the 35ns speed grade relative to system timing constraints. Evaluate the TQFP package suitability for PCB layout density. Verify that the 5V logic interface matches the target system voltage levels without additional level shifting.
