7006L35PF8

Overview

The Renesas Electronics Corporation 7006L35PF8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) IC. It provides a storage capacity of 128 kilobits organized as 16K words by 8 bits. The device features a parallel interface with a maximum access time of 35 nanoseconds. It operates on a single 4.5V to 5.5V power supply and supports battery backup for data retention down to 2V. The component is housed in a 64-pin Thin Quad Flatpack (TQFP) package measuring 14x14 mm.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent reads from both ports.
• On-chip hardware support for semaphore signaling and port arbitration logic.
• Automatic power-down mode controlled by chip enable signals for low standby power.
• TTL-compatible inputs and outputs with full interrupt flag functionality.

Applications

• Stand-alone 128K-bit dual-port memory systems
• Master/Slave configurations for 16-bit or wider word systems
• Industrial control applications requiring hardware semaphore support

Procurement Notes

Verify the specific suffix 'PF8' against official Renesas documentation to confirm package and tape-and-reel specifications. Confirm RoHS compliance status as legacy variants may differ. Check for End-of-Life notices or discontinuance announcements prior to procurement planning.

Selection Notes

Select this component when true dual-port capability with hardware arbitration is required. Ensure the system voltage aligns with the 4.5V to 5.5V range. Consider the 35ns access speed relative to system clock requirements. Verify that the 64-TQFP package fits the PCB layout constraints.

Part Context

This part belongs to the 7006L series of dual-port SRAMs from Renesas. It shares architectural similarities with other members like the 7006L15 and 7006L20, differing primarily in access speed and packaging options. The series is designed for high-speed data buffering and sharing between two processors.

Replacement Considerations
