7007L20PFI8

Memory IC Overview

The Renesas Electronics Corporation 7007L20PFI8 is a dual-port static random access memory (SRAM) device with a storage capacity of 256 kbit, organized as 32k x 8. It features an asynchronous parallel interface with a maximum access time of 20 ns. The component operates on a single 4.5V to 5.5V power supply and supports surface mount installation in a PLCC-68 package. It is rated for industrial operating temperatures ranging from -40°C to +85°C.

Memory IC Feature Summary

• True dual-port architecture enabling simultaneous independent access by two processors
• Fully asynchronous operation from either port without clock synchronization requirements
• On-chip hardware support for semaphore signaling and automatic power-down modes

Memory IC Applications

• High-speed data buffering between microprocessors and peripherals
• Master/slave dual-port RAM configurations for 16-bit or wider systems
• Industrial control systems requiring reliable data exchange under varying loads

Memory IC Procurement Notes

Verify the specific suffix PFI8 against official Renesas documentation to confirm package type and lead-free status. Confirm RoHS compliance and moisture sensitivity level prior to assembly. Check for end-of-life notices or obsolescence warnings, as availability may be restricted. Ensure voltage levels match system requirements before integration.

Memory IC Selection Notes

Select this component when a 256 kbit dual-port SRAM with 20 ns speed is required. The PLCC-68 package suits applications needing robust surface-mount connectivity. Verify that the 4.5V to 5.5V supply range aligns with the target system's power rails. Consider thermal management within the specified -40°C to +85°C industrial temperature range.

Memory IC Part Context

This part belongs to the Renesas 7007L series of high-speed dual-port SRAMs. These devices are designed for standalone use or as master/slave combinations. The series emphasizes low standby power and TTL-compatible logic levels, making them suitable for complex embedded architectures requiring fast, non-blocking memory access.

Memory IC Replacement Considerations

Consult official Renesas cross-reference guides for verified substitutes. Generic equivalents may not match the specific pinout or arbitration logic. Verify that any replacement maintains the 32k x 8 organization and 20 ns access time.
