7005S20J8

Overview

The Renesas Electronics Corporation 7005S20J8 is a high-speed, asynchronous dual-port static random access memory (SRAM) device. It provides a storage capacity of 64 kbit organized as 8k x 8 bits. The component features parallel interface communication with an 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, drawing a maximum current of 290 mA. The device is housed in a 68-pin PLCC surface-mount package and supports an operating temperature range from 0°C to +70°C.

Feature Summary

• Supports simultaneous independent reads and writes at either port without bus contention
• Includes on-chip hardware logic for semaphore signaling and interrupt flags between ports
• Features automatic power-down mode controlled by chip enable signals for low standby power

Applications

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

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package integrity upon receipt, ensuring no damage to the PLCC-68 leads. Check datasheet revisions for any pinout or electrical specification updates prior to integration into new designs.

Selection Notes

Select this component when true dual-port functionality with hardware arbitration is required. Ensure the 20 ns access time meets system timing constraints. Verify that the 68-pin PLCC package fits the PCB layout. Consider thermal management for the specified operating temperature range. Evaluate alternative packages if different form factors are needed for the same memory architecture.

Part Context

This device belongs to the Renesas 7005 series of dual-port SRAMs. It shares architectural similarities with other variants like the 7005L45J8 and 7005S25J8, differing primarily in access speed and package type. The series is designed for applications requiring concurrent access to shared memory resources without external arbitration logic.

Replacement Considerations

Public confirmed substitute part numbers include IDT7005S20J8.
