7008L20PFGI

Memory IC Overview

The Renesas Electronics Corporation 7008L20PFGI is a high-speed, asynchronous dual-port static random-access memory (SRAM) IC. It features a storage capacity of 512 kilobits organized as 64K words by 8 bits. The device utilizes a parallel interface with a maximum access time and write cycle time of 20 nanoseconds. It operates on a single 5V power supply within a voltage range of 4.5V to 5.5V. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm, designed for surface-mount installation. It supports an industrial operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous independent reads and writes to the same memory location from either port.
• 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 minimize standby power consumption.
• TTL-compatible operation with a single 5V power supply requirement.

Memory IC Applications

• Stand-alone 512k-bit dual-port memory systems
• Master/slave dual-port configurations for 16-bit or wider word systems
• Battery-backed memory applications requiring low-voltage data retention

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm package marking and date codes against official datasheets. Check for RoHS3 compliance if required by current assembly standards. Ensure proper ESD handling during storage and installation. Validate pin compatibility with existing PCB footprints before procurement.

Memory IC Selection Notes

Select this component when simultaneous bidirectional data access is required without external arbitration logic. Suitable for systems needing fast, deterministic memory access times under 20ns. Consider thermal management for TQFP packages in enclosed environments. Verify voltage tolerance matches system power rails. Evaluate alternative packages like PLCC if leaded soldering is preferred over surface mount.

Memory IC Part Context

This part belongs to the IDT 7008 series of dual-port SRAMs, originally developed by Integrated Device Technology and later acquired by Renesas. The series is known for its true dual-port capability and hardware semaphore support. The 7008L20 variant specifically denotes the 20ns speed grade within the 512Kb density family.
