7008L20PFGI8

Memory IC Overview

The Renesas Electronics Corporation 7008L20PFGI8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) IC. It provides a total storage capacity of 512 kilobits, organized as 64K words by 8 bits. The device features true dual-ported memory cells that allow simultaneous independent reads and writes from two separate ports without conflict. It operates with a single 5V power supply within a voltage range of 4.5V to 5.5V. The component supports parallel interface communication with an access time of 20 nanoseconds. It is housed in a 100-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm, suitable for surface-mount assembly.

Memory IC Feature Summary

• True dual-ported architecture enabling simultaneous independent access to the same memory location from both ports.
• On-chip hardware support for semaphore signaling and port arbitration logic to manage data integrity between ports.
• Automatic power-down feature controlled by chip enable signals to achieve low standby power consumption.
• TTL-compatible inputs and outputs designed for straightforward integration with standard digital logic systems.

Memory IC Applications

• Master/slave dual-port configurations for expanding data bus widths to 16 bits or more.
• High-speed data buffering in telecommunications equipment requiring concurrent port access.
• Industrial control systems operating within the specified industrial temperature range.
• Battery-backed memory applications utilizing the device's 2V data retention capability.

Memory IC Procurement Notes

Verify current availability status as this part number may be subject to end-of-life restrictions. Confirm package authenticity and moisture sensitivity level handling requirements upon receipt. Ensure design compatibility with the 100-TQFP footprint and 5V logic levels. Check for any recent product change notices regarding labeling or assembly site modifications before finalizing procurement plans.

Memory IC Selection Notes

Select this component when simultaneous independent access to shared memory is required without external arbitration circuitry. It is appropriate for designs needing 512Kb capacity with 20ns speed in a 100-pin surface-mount package. Consider the 5V supply requirement and industrial temperature range suitability. Evaluate if the asynchronous operation mode meets the system timing constraints compared to synchronous alternatives.

Memory IC Part Context

This device belongs to the 7008L series of dual-port SRAMs manufactured by Renesas Electronics. It is functionally equivalent to the IDT7008L20 variant under previous branding. The series is designed for standalone use or cascaded master/slave arrangements. It shares architectural similarities with other members of the 7008 family but differs in pinout and specific speed grades.
