7005L20PF8

Overview

The Renesas Electronics Corporation 7005L20PF8 is a high-speed, asynchronous dual-port static random access memory (SRAM) IC. It provides a storage capacity of 64 kbit organized as 8k x 8 bits. The device features parallel interface operation with a maximum access time of 20 ns. It operates on a single 5V power supply within a voltage range of 4.5 V to 5.5 V. The component is housed in a 64-pin Thin Quad Flat Package (TQFP) suitable for surface mount technology. It supports simultaneous independent reads and writes from either port.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent read/write operations from both ports without conflict.
• On-chip hardware support for semaphore signaling and interrupt flags to facilitate data synchronization between processors.
• Automatic power-down feature controlled by chip enable inputs to minimize standby power consumption during idle periods.

Applications

• Stand-alone 64K-bit dual-port RAM systems
• Master/Slave dual-port configurations for 16-bit or wider word systems
• Battery-backed memory applications requiring low standby current

Procurement Notes

Verify the specific suffix PF8 confirms the 64-TQFP package and commercial temperature range. Confirm RoHS compliance status as legacy variants may differ. Check manufacturer lifecycle status for obsolescence notices. Validate pinout compatibility against existing PCB layouts before integration.

Selection Notes

Select this component when simultaneous bidirectional data transfer is required without external arbitration logic. Ensure the design accommodates the 64-pin TQFP footprint and 5V logic levels. Consider thermal dissipation requirements based on the maximum operating current specifications provided in the datasheet.

Part Context

This part belongs to the Renesas 7005 series of dual-port SRAMs. It shares architectural similarities with other members like the 7005S20J8 but differs in package type and speed grade. The series is designed for applications requiring high-speed data sharing between two independent masters.

Replacement Considerations

IDT7005L20PF8 is a confirmed equivalent part number under the Integrated Device Technology brand, which merged into Renesas. Verify pin-to-pin compatibility and electrical parameters before substitution.
