7005L45J8

Overview

The Renesas Electronics Corporation 7005L45J8 is a high-speed asynchronous dual-port static random access memory (SRAM) with a storage capacity of 64 kbit, organized as 8k x 8. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum access time of 45 ns. The device supports parallel interface communication and draws a maximum power current of 210 mA. Designed for surface-mount installation, it is housed in a PLCC-68 package. The component functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Supports simultaneous independent reads from both ports without conflict
• Includes on-chip hardware semaphore signaling for port arbitration
• Features automatic low standby power mode controlled by chip enable

Applications

• Stand-alone 64K-bit dual-port memory systems
• Master/Slave dual-port RAM configurations for 16-bit or wider data buses
• Battery-backed applications requiring 2V data retention

Procurement Notes

Verify the End-of-Life status before design finalization, as discontinuance notices may apply. Confirm RoHS compliance requirements against specific project standards, as this variant is marked non-compliant. Validate that the PLCC-68 package aligns with available PCB footprint libraries and assembly capabilities. Ensure the 45 ns access speed meets system timing constraints.

Selection Notes

Select this component when a 45 ns access time is sufficient for the target application architecture. The PLCC-68 package is suitable for surface-mount processes requiring J-leads. Verify that the 4.5 V to 5.5 V supply range matches the system power rails. Consider the industrial temperature range if operation exceeds standard commercial limits.

Part Context

This part belongs to the Renesas 7005 series of dual-port SRAMs. It shares architectural similarities with variants like the 7005S20J8 and IDT7005L45J8, differing primarily in access speed and manufacturer branding. The series provides true dual-ported memory cells allowing concurrent access to the same location.

Replacement Considerations

IDT7005L45J8 is a documented alias for this component.
