7006L25PF

Overview

The Renesas Electronics Corporation 7006L25PF is a high-speed 128 kbit (16K x 8) dual-port static random access memory. It features asynchronous parallel interface operation with a maximum access time of 25 ns. The device operates on a single 5V power supply within a voltage range of 4.5 V to 5.5 V, drawing a maximum current of 280 mA. It is housed in a 64-pin TQFP surface-mount package and supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• True dual-ported architecture enabling simultaneous independent read/write operations by two separate processors
• On-chip hardware support for semaphore signaling and port arbitration logic
• Automatic low standby power mode controlled by chip enable inputs

Applications

• Stand-alone 128K-bit dual-port RAM systems
• Master/Slave dual-port configurations for 16-bit or wider word systems
• Battery backup applications requiring data retention

Procurement Notes

Verify the exact suffix against official documentation, as 'PFGI' and 'PFI' variants exist with distinct packaging and environmental ratings. Confirm lead times directly with the manufacturer due to reported long delivery periods. Ensure compatibility with existing PCB footprints for the 64-pin TQFP package before procurement.

Selection Notes

Select this component when simultaneous bidirectional data transfer between two masters is required without bus contention. The 25 ns speed grade suits moderate-to-high frequency asynchronous interfaces. Verify that the industrial temperature range (-40°C to +85°C) meets system environmental requirements compared to commercial grades.

Part Context

This part belongs to the 7006L series of high-speed CMOS dual-port SRAMs manufactured by Renesas Electronics. The series provides flexible memory solutions for complex embedded systems requiring shared memory resources. It serves as a direct replacement for legacy IDT 7006 family components in established designs.
