7005S35JI8

Overview

The Renesas Electronics Corporation 7005S35JI8 is an asynchronous dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 64 kbit, organized as 8k x 8 words. The device features a parallel interface with a maximum access time of 35 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 68-PLCC package. The component functions within an ambient temperature range of 0°C to +70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation for flexible system integration
• Parallel data interface for standard memory bus connectivity

Applications

• High-speed data buffering in embedded systems
• Cache memory implementation in microcontroller architectures
• Data logging applications requiring rapid write cycles

Procurement Notes

Verify the specific suffix 'I8' against official Renesas documentation to confirm package and environmental specifications. Confirm RoHS compliance status as legacy variants may differ. Check current lifecycle status as older SRAM models are frequently discontinued. Ensure ESD handling protocols are followed during procurement and assembly due to moisture sensitivity classification.

Selection Notes

Select this component when dual-port functionality is required for concurrent processor access. Compare access times and power consumption against single-port alternatives if only one master exists. Verify that the 68-PLCC footprint matches the target PCB layout. Consider thermal dissipation requirements given the parallel interface characteristics and operating voltage constraints.

Part Context

This part belongs to the Renesas 7005S series of dual-port SRAMs. It shares architectural similarities with other members like the 7005S15 and 7005L35, differing primarily in speed grades and package types. The series is designed for applications requiring high-speed memory sharing between multiple masters without complex arbitration logic.

Replacement Considerations

Official substitutes include IDT7005S35J8. Verify pin compatibility and electrical parameters before substitution.
