7008L15PFG8

Memory IC Overview

The Renesas Electronics Corporation 7008L15PFG8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) IC. It provides a storage capacity of 512 kilobits organized as 64K words by 8 bits. The device features a parallel interface with a maximum access time of 15 nanoseconds. It operates on a single 5-volt 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 and supports surface-mount installation. It is designed for industrial temperature ranges from 0°C to 70°C.

Memory IC Feature Summary

• True dual-ported architecture enabling simultaneous independent reads and writes from two separate ports without external arbitration logic.
• On-chip hardware support for semaphore signaling and port arbitration to manage concurrent access conflicts between the two ports.
• Automatic power-down feature controlled by chip enable signals to reduce standby power consumption during inactive periods.
• TTL-compatible single 5V power supply operation allowing direct interfacing with standard digital logic systems.

Memory IC Applications

• High-speed data buffering in telecommunications equipment requiring low-latency memory access.
• Master/slave configurations in 16-bit or wider microprocessor systems for expanded word width operations.
• Real-time signal processing applications where simultaneous data access from multiple processors is required.
• Industrial control systems utilizing asynchronous communication protocols for reliable data exchange.

Memory IC Procurement Notes

Verify the specific suffix 'G8' against official Renesas documentation to confirm tape-and-reel packaging and RoHS compliance status. Confirm current production status as previous listings indicated obsolescence for similar variants. Ensure compatibility with existing PCB footprints for 100-TQFP packages. Check for moisture sensitivity level requirements during storage and handling. Validate that the 15ns access time meets system timing constraints.

Memory IC Selection Notes

Select this component when a true dual-port SRAM with 512Kb density and 15ns speed is required. It is suitable for designs needing independent port access without external bus controllers. Consider the 100-pin TQFP package if space allows for surface-mount assembly. Evaluate power consumption needs as the device offers automatic power-down modes. Compare against single-port alternatives if only one active master is present in the design.

Memory IC Part Context

The 7008 series represents Renesas's line of high-performance asynchronous dual-port SRAMs. These devices are engineered for applications demanding fast, conflict-free data sharing between two independent masters. The 7008 variant specifically targets 512Kb capacity needs with an 8-bit data bus width. This family supports flexible system architectures by eliminating the need for complex external arbitration circuitry.

Memory IC Replacement Considerations

Official substitutes include the IDT7008L15PF and IDT7008S15PF8. Verify pinout compatibility and electrical specifications before substitution. Note that some variants may differ in packaging type or environmental compliance. Consult Renesas datasheets for exact functional equivalence and mechanical dimensions.
