7027L55PF8/2909

Memory IC Overview

The Renesas Electronics Corporation 7027L55PF8/2909 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 512 kilobits, organized as 32K words by 16 bits. The device utilizes an asynchronous parallel interface with a maximum access time of 55 nanoseconds. It operates on a single 4.5V to 5.5V power supply and supports surface-mount installation in a 100-lead Thin Quad Flat Pack package measuring 14x14 millimeters. The component functions within a commercial temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations from two separate ports without external arbitration logic.
• Features fully asynchronous operation allowing flexible timing control for both port interfaces.
• Integrates automatic power-down capabilities controlled by chip enable signals to minimize standby current consumption.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in industrial control systems
• Data logging applications requiring rapid sequential access

Memory IC Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact packaging configuration and lead-free status. Confirm RoHS compliance requirements prior to integration. Ensure the selected variant matches the required thermal grade for the intended operating environment. Cross-reference part numbers with authorized distributors to avoid obsolete or counterfeit inventory sources.

Memory IC Selection Notes

Select this component when a system requires true dual-port memory architecture for concurrent data handling between independent processors. The 55-nanosecond access speed suits moderate-to-high throughput applications where deterministic latency is critical. Evaluate the 100-pin TQFP footprint against available board space constraints. Consider the 5-volt logic compatibility for direct interfacing with standard microcontrollers.

Memory IC Part Context

This device belongs to the Renesas 7027L series of dual-port SRAMs, designed for high-performance embedded applications. The series offers various access speeds and organization options to accommodate different bandwidth requirements. The 7027L family maintains pin compatibility across certain variants to simplify design upgrades.

Memory IC Replacement Considerations

Consult official substitution guides for equivalent dual-port SRAM devices with matching 512Kb capacity and 100-pin TQFP packages. Verify electrical parameter alignment before replacing existing components in production hardware.
