7008S55PFGI

Memory IC Overview

The Renesas Electronics Corporation 7008S55PFGI is a high-speed, asynchronous dual-port static random-access memory (SRAM) integrated circuit. It provides a total storage capacity of 512 kilobits, organized as 64K words by 8 bits. The device features parallel interface access with a maximum access time of 55 nanoseconds. It operates on a single 5V power supply within the voltage range of 4.5V to 5.5V. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm and supports surface-mount installation.

Memory IC Feature Summary

• Supports simultaneous independent read/write operations from two separate ports without conflict.
• Includes on-chip hardware for semaphore signaling to manage data integrity between ports.
• Features automatic power-down mode controlled by chip enable signals for low standby power consumption.
• Provides TTL-compatible logic levels for direct interfacing with standard digital systems.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data acquisition systems requiring concurrent port access
• Industrial control units needing reliable volatile storage

Memory IC Procurement Notes

Verify the exact suffix designation against official manufacturer documentation, as variations such as PFGI may indicate specific package or temperature grades. Confirm RoHS compliance status, as older variants often lack environmental certification. Ensure the source document explicitly lists the 7008S55PFGI part number to avoid confusion with similar models like the 7008L series which differ in speed and temperature range.

Memory IC Selection Notes

Select this component when a system requires true dual-port architecture for concurrent master-slave or peer-to-peer communication. It is suitable for applications needing fast 55ns access times with a 512Kb density. Consider the 100-pin TQFP footprint for PCB layout constraints. Verify that the operating environment falls within the commercial temperature range if industrial ratings are not required.

Memory IC Part Context

This device belongs to the Renesas 7008S family of asynchronous dual-port SRAMs. It is designed to expand data bus widths to 16 bits or more when combined in master/slave configurations. The technology utilizes CMOS processes to ensure high speed and low power consumption compared to earlier bipolar implementations.
